Lipid Transport

LIPOPROTEINS

Once lipids are disassembled in the intestinal lumen and mucosal cell (enterocyte) they are reassembled in the mucosal cell as chylomicrons (CM's) and very low density lipoproteins (VLDL's). These vehicles contain primarily nonpolar cholesterol esters and triglycerides in the core and polar cholesterol, protein, and phospholipids in their membranes. (Fig. 20)

[ Lipoproteins Image ]

http://www.wysong.net/articles/lipid/figures/figure20.jpg

They are transported via the lymph and blood circulation to the liver, fat depots, and muscles. There the endothelial enzyme lipoprotein lipase removes the lipid contents.

Lipid carrying vehicles are also made by the liver primarily as very low density lipoproteins (VLDL) and these function to move lipids made by the body itself into tissues. On the other hand, high density lipoproteins (HDL), which are made in the intestines and liver, function primarily to reverse this process and transport lipids from tissue to liver hepatocytes.1 HDL's are of two types: HDL3 and HDL2. HDL3 is an empty package composed of a bilayer lipid membrane plus proteins. Lysolecithin cholesterol acyl transferase (LCAT) and apoprotein A associated with HDL3 remove free cholesterol from the blood, esterify it and fill the HDL3 package.

The LCAT enzyme uses the fatty acid in the number two position of lecithin to esterify to cholesterol. If this fatty acid is saturated, the process is inhibited: if it is unsaturated, the process is enhanced. Thus, cholesterol blood clearing by HDL3 is linked to dietary intake of saturated and unsaturated fatty acids. High saturated triglycerides are often clinically associated with high blood cholesterol levels.

As HDL3 swells with cholesterol ester, it becomes HDL2, which in the liver releases its cholesterol through the action of hepatic lipase. Released cholesterol is conjugated with the amino acids glycine (predominantly in most species) and taurine (predominantly in cats) to form bile salts which are then excreted in the bile into the small intestine.2,3 Some cholesterol is then reabsorbed via the enterohepatic circulation and some passes with the feces. The less reabsorbed, the lower the blood levels of cholesterol. A variety of complex factors influences the reuptake of bile cholesterol. For example, some of the beneficial effects of fiber and certain bowel microorganisms can be related to decreasing cholesterol uptake.4,5

Characterization of lipid transport vehicles is based on physical density, size and ratios of constituents. Chylomicrons are the largest particles, the very low density lipoprotein (VLDL) is the next largest, the intermediate density lipoprotein (IDL) is the next largest, the low density lipoprotein (IDL) is the next largest, and then high density lipoproteins (HDL) are the smallest. In terms of their constituents, as the particle becomes smaller as it is hydrolyzed by lipoprotein lipase on capillary endothelial cells, its protein and cholesterol content becomes greater, triglyceride content becomes smaller and its density increases.6 Thus chylomicrons are laden with lipid but lean of protein, whereas high density lipoproteins contain smaller amounts of lipid and larger measures of protein. (Fig. 21)

Diagnostically the measure of these lipid carriers in the blood is important as indicators of risk particularly to cardiovascular disease. If there are high levels of LDL's, this would be unfavorable whereas high levels of HDL's would be favorable. High levels of LDL's mean that there is a large amount of circulating cholesterol which may have atherogenic potential. On the other hand, a high level of HDL's would mean that lipid stores are being mobilized from tissue and metabolized in the liver to be excreted in the bile.7

APOPROTEINS

The proteins associated with lipid carriers help solubilize the lipids, and identify them for enzymatic action. There are a host of these apoproteins. Some of those believed to be most important diagnostically are B, found on LDL's and VLDL's, E, found on IDL's, and A. found on HDL's. Apoprotein B on LDL's and VLDL's tags lipids for uptake by liver cells or scavenger cells in blood vessel walls. Apoprotein A tags HDL's for liver uptake. Another apoprotein, C-2, serves as a cofactor for lipoprotein lipase which hydrolyzes the contents of low density lipid carriers on the endothelial wall. (Fig 22)

[ Lipoprotein Metabolism Image ]

http://www.wysong.net/articles/lipid/figures/figure22.jpg

This is a very brief overview of some increasingly complex biochemistry coming to light.8-l0 Diagnostically, identifying apoproteins may be most revealing since they are more specific than simply measuring cholesterol or lipoproteins. High apoprotein A, for example, indicates high levels of HDL's whereas high levels of B indicate high levels of LDL's.

Lipoprotein (a) (different than A) may be one of the best independent markers for both cardiovascular risk and severity of existing disease. It is comprised of LDL and apoproteins B-100 and (a). Lp(a) is genetically controlled and due to the homology between apo (a) and plasminogen, a blood clot lysing factor, it interferes with clot lysis and adheres LDL to the endothelial surface where it can initiate atherosclerosis. Lp(a) levels greater than 50 mg/ell, plus high LDL levels can increase cardiovascular disease risk six fold. 11-14

TARGET BLOOD LEVELS

Blood cholesterol is increasingly used as a screening tool for cardiovascular risk. One third of all adults in the U.S. now know their blood cholesterol level. How much is the right amount? Looking at just LDL cholesterol, it is argued that since newborns have levels of approximately 30 mg/dl and that 25 mg/dl is sufficient to nourish the body's tissue with cholesterol, and that species which do not experience cholesterol-related cardiovascular disease consistently have LDL cholesterol levels of less than 80 mg/dl, a recommended level of 25-80 mg/dl is considered to be in the healthy range. This is 1/5 the level normally seen in Western societies.15 Other tests measuring HDL, total cholesterol, triglycerides, apoproteins and cholesterol/HDL and Apo A/Apo B ratios are also used to determine cardiovascular risk.

[ Blood Lipid Levels Image ]

http://www.wysong.net/articles/lipid/figures/figure22a.jpg

By measuring various lipid factors it is possible to compile a composite lipid risk score.16 Diagnostic values, however, are subject to error both in testing and interpretation. We are far from being able to accurately quantitate health. A false "positive" risk could create anxiety and disease (convert a normal person to a patient) where none was present, and a false "negative" risk could lead to complacency and exacerbation of existing disease. Therefore, laboratory results and "normal" values should always be viewed with suspicion and used only as leads for further diagnostic evaluation.17-20

CHOLESTEROL

The level of various lipids in the blood, including cholesterol, is dependent upon cholesterol ingested and the amount of cholesterol being synthesized within the body. Cholesterol is an extremely important compound that makes up part of cellular membranes, is a substrate for the synthesis of a variety of hormones and vitamin D, and also is a component of bile acids which permit the digestion of lipids.

If cholesterol is a normal and healthy physiological compound, why such an uncomplimentary reputation? Government, through the National Cholesterol Education Program (NCEP) seeks to decrease the nation's blood cholesterol levels. This is the largest medical intervention in the history of the U.S.A. It has not been done without cause. Heart disease takes the life of one of every two in this country. Cholesterol is an integral part of the atherosclerotic plaque and major studies such as the federally supported Framingham (Mass.) Heart Study following thousands of subjects since 1948 show significant correlations between cholesterol and heart disease.

Simply lowering blood cholesterol is not a panacea, however. If the diet were totally depleted of cholesterol, the body would be forced to produce that which is necessary to sustain life. If blood cholesterol is unusually low (less than 160 mg/dl) the risk of stroke increases three fold and the risk of cancer increases two fold.21, 22 Thus dietary cholesterol, although perhaps a contributing factor to disease, is not likely a "poison" in its natural food form. The body has elaborate biochemical systems designed to synthesize approximately 80% of the cholesterol found within normal tissue. The body evidently thinks cholesterol is important. Cholesterol synthesis uses foods such as sugar, alcohol and starch to form the precursor acetate. A host of enzymes specifically designed to assure cholesterol availability then builds the complex molecule from acetate.

Cholesterol has been a part of the diet since the beginning of life yet cholesterol-linked disease is recent, reportedly being of significant consequence only since about the 1930's. The Masai in Tanzania consume up to 2,000 mg of cholesterol per day yet their serum levels remain low, 115-145 mg/dl.23 A study of South African egg farm workers who consume large numbers of eggs resulting in a cholesterol intake of 1,200 mg per day have serum cholesterol levels of 180 mg/dl.

So why would cholesterol cause cardiovascular disease, the number one killer in many developed nations, when:

1. Cholesterol has been a part of the natural diet of humans and animals for millennia:

2. Cardiovascular disease is not significant in many so societies consuming high levels of cholesterol:

3. As cardiovascular disease increased, cholesterol and saturated fat levels have remained relatively constant: (Fig. 24) and,

4. As deaths from heart attacks decreased by 42% from 1963 to 1986, average cholesterol levels decreased only 3%.24

Some argue that the apparent paradox of increased cardiovascular disease is a result of increased life span creating an older population naturally more given to degenerative diseases. But contrary to popular belief, life span (the length of life one can expect to live, life potential) has not increased significantly since actuarial data has been reliably tabulated. Life expectancy (the average length of life of a population), on the other hand, has increased (47 years in 1900, 73 years today) due to decreased infant mortality resulting from better public hygiene and food distribution. Thus although at birth our chance of survival to a natural old-age death is increased, our age at the time of a natural death has not increased over that of our distant ancestors.25 Increased cardiovascular disease rates are therefore not simply a function of the increasing average age of our population.

The evidence is, however, quite convincing that cardiovascular disease is linked to diet in some way. Additionally, atherosclerotic plaques in vessel walls (particularly carotid and coronary) do indeed contain cholesterol although it may be difficult to prove that cholesterol's presence is a cause rather than a result of atherosclerosis. The issue is not closed. There is evidence that cardiovascular disease is ancient and that genetics and the stresses of modern living. particularly. may be more important than diet.26

It is likely that atherosclerosis is a consequence of the influence of a variety of modern factors. These include but are not limited to sedentary living, stress, environmental pollution and diet. Looking only at diet, correlations between cardiovascular disease and increased consumption of proinflammatory omega-6 oils, processed (hydrogenated, oxidized) polyunsaturated fatty acids found in manufactured margarines and a wide range of other commercial processed products and oxidized cholesterol are far more logically convincing as etiologic factors than natural cholesterol or saturated fats.

[ The Cause Of Cardiovascular Disease Image ]

http://www.wysong.net/articles/lipid/figures/figure23.jpg

The early 1900's, marking a seemingly rapid rise in cardiovascular disease, also marked the rise in the consumption of the fabricated, fractionated processed diet.27-30 (Fig. 23) Cholesterol as a part of raw, whole, natural foods (natural here would also mean food animals in the wild, not factory farmed) has not been demonstrated to be linked to any disease conditions. The putative relationship between cholesterol and disease confuses definitions. The cholesterol referred to and shown through metanalysis, retrospective studies and prospective controlled clinical trials to be positively associated with atherosclerosis is not "natural" cholesterol. For example, in animal studies which induce atherosclerosis, an oxidized ("activated") cholesterol is used.31,32 Additionally, human studies measure the effects of processed fats and oils as they occur in processed foods, not lipids as they occur in raw, natural, whole, fresh foods. Cholesterol in a homogenized, pasteurized butter, scrambled egg, fastfood burger or a grilled steak is a whole different creature than the cholesterol found in the living tissue of a wild antelope. (Fig.24)

Not only is the form of the cholesterol different (there are over 60 different cholesterol oxide species alone) but its context is totally different. The value of food is not only determined by its individual components, but by the company kept, the kind and relative amounts of neighbors -- its synergonic nature. Processed foods are made from fractionated ingredients which are modified and then reassembled to create taste, shelf life and profit. Afresh, raw, natural food is entirely different, it is a complex milieu of interrelationships. It is a whole more than an assemblage of parts. A real food is no more X% protein, fat, minerals, vitamins and carbohydrates than a novel is X% ink, cellulose and glue.

Although experiments have yet to be devised to measure the effects of natural cholesterol by means of an all raw diet, the results are predictable. The grandest experiment of all, that of the development and sustenance of life on the planet prior to the roller mill, extruder, solvent extractor and hydrogenator, has already given the answer. Life owes its very existence to the presence of whole raw natural food. Such food is not the cause of disease, it is the cause of life.

[ Cholesterol Forms Image ]

http://www.wysong.net/articles/lipid/figures/figure24.jpg

Natural food was the only food available until the technological era. The new food, the new cholesterol, hydrogenated and oxidized fatty acids and their new artificial combinations, were born out of technology. Also, it is argued, born at that time was the plaque of atherosclerosis. Thus the relationship of "cholesterol" and "saturated fats" to atherosclerosis is an indictment of food processing and not true food cholesterol as a part of whole, raw, natural foods.

REGULATING BLOOD LIPIDS

The level of cholesterol in the blood is regulated by a wide array of feedback mechanisms. If there is an excessive amount of LDL cholesterol in the bloodstream, receptors in the liver responsible for taking up these transport units will become saturated. When high blood levels of LDL are reached, the liver cells decrease the number of LDL receptors thus decreasing the liver's ability to clear the blood of cholesterol. Thus when the liver is saturated with cholesterol and it needs no more, it simply shuts down the production of LDL receptors. At the same time, cholesterol excretion of bile acids would be increased to capacity. If the diet is low in fiber, or digestive tract microflora are out of balance, much of this cholesterol would be reabsorbed thus contributing to escalating blood levels of cholesterol. The cycle perpetuates itself continuing to build higher and higher blood levels of cholesterol. A familial hyperlipidemic condition whereby receptors for taking up LDL are defective can also contribute to exaggerated blood levels of cholesterol in some individuals.33 (Fig. 25)

High blood cholesterol and saturated fat levels and unfavorable lipoprotein ratios are a reality for many individuals and may place them at risk of life threatening disease. Improvements in lifestyle can decrease the absorption of cholesterol, increase its excretion, and change the ratio of LDL's to HDL's resulting in blood levels which are more conducive to

[ Cholesterol Metabolism Image ]

http://www.wysong.net/articles/lipid/figures/figure25.jpg

the healthy state. Such improvements include: (1) increasing the consumption of fresh fruits and vegetables, and: (2) consuming a variety of high fiber foods containing various sterols which compete for uptake of cholesterol in the intestinal tract combined with: (3) a lower consumption level of processed cholesterol combined with: (4) increased exercise: (5) and perhaps increased consumption of omega-3 and omega-9 fatty acid containing foods. Omega-3's are extremely effective in mixed hyperlipidemias, and omega-9's are reported to have the ability to decrease LDL's while increasing HDL's.34-37 Decreasing saturated fat consumption also may help since saturated triglycerides are hydrophobic and encourage the formation of the higher fat and cholesterol carrying LDL's and VLDL's and retard cholesterol uptake by HDL's.

Additionally, certain drugs (Probucol, Cholestyramine, Colestipol, Clofibrate, Gemfibrozil, Lovastatin and others) have been devised to decrease the hepatic synthesis of cholesterol and decrease the amount of cholesterol that is intestinally absorbed or reabsorbed from bile into the enterohepatic circulation which may be required if more natural modifications are not effective. (These are not without significant dangers, however.) 38-42

Diet modification and lifestyle changes are sensible tools to improve health and will offer the greatest chance of optimizing health and preventing disease. Careless hedonistic living based on the presumption that early diagnosis and heroic invasive procedures, such as transplants, angioplasty, bypasses, or drugs will provide forgiveness is a poor second to thoughtful preventive practices.

Hairy Problems

"Dearest granddaughter, come close and look into my eyes." Grandmother Growth beckons and her voice grows deeper and more resonant. "Look deep into my eyes and acknowledge the beauty there.

"Yes, my skin is wrinkled. My face is the face of age, and to many, that is fearful. But my beauty, like my wise blood, now resides inside of me. Can you see it? Can you feel it? Can you look beyond the hair on my chin?" she says grinning, flicking her fingers under her chin in a most unladylike manner.

"Can you forgive the places where my scalp shines through? Can you find the truth of my beauty, the beauty of age, which is so different from the beauty of youth?" Her eyes grow fierce, but sparkle with amusement. "I know you can, for I know how beautiful I am."

Grandmother Growth takes your chin in her strong hand and looks at you with eyes so intense you fear you may catch on fire. She commands: "When you look into your mirror, I ask you to look deep into your own eyes and to acknowledge your own inner beauty.

"I know, I know, metamorphosis is changing you and you don't like it. Like a teenager, you peer and peer into the looking glass, noting every new wrinkle, every hair on your face (and other new places). Counting each grey hair as it grows. Worrying that your hair seems to fall out by the handful.

"Dear one, my most precious child, take care, but do not fret. And do not tell yourself that you are becoming ugly. I know it is difficult, in fact it may be one of the most difficult tasks of your menopause, but you must recast your own opinion of beauty so that it includes old women who have hairy problems and live well with them - like you!"

Too much hair (on the chin), too little hair (on the scalp), falling hair, thinning hair, greying hair - no matter what the complaint, many women notice something happening to their hair during menopause. As hormone levels shift during the menopausal years, hair responds to the changing hormones by changing texture, falling out, or by growing in "odd" places. Here are remedies for those who want more hair, and for those who want less.

HAIR LOSS (ALOPECIA) & GREY HAIR

STEP 1. COLLECT INFORMATION

Menopause does not cause grey hair; taking hormones doesn't stop it. Greying, thinning hair is a normal part of aging. Women whose menopause is induced in their 20s and 30s do not suddenly go grey.

Hair loss at mid-life (androgenic alopecia) is more strongly linked to genes than diet or lifestyle. Those of European origins are far more likely to experience it than Asians, Native Americans, Africans, or African-Americans. Hair loss starts earlier and becomes more extreme on men's heads, but just as many women deal with receding hairlines and balding patches. Roughly half of all women experience some hair loss during their menopausal years. Two-thirds of post-menopausal women deal with thinning hair or bald spots. And no one likes it. Americans spend a billion dollars a year trying to regrow their hair!

Normal hair loss (50-100 hairs a day) is gradual. Sudden unexplained loss is not normal. Events which can trigger hair loss include pregnancy, childbirth, menopause, severe emotional stress, rapid or profound weight loss, thyroid disorders, pituitary problems, malnutrition, iron deficiency, lack of protein, large doses of vitamin A, chemotherapy, radiation, general anesthesia, chronic illness, scarlet fever, syphilis, certain medications (see Step 5), and hair abuse including bleaching, permanents, tight braids, tight pony tails, tight wigs, and tight hats.

(The National Alopecia Areata Foundation, 710 C St, Ste 11, San Rafael, CA 94901 (415-456-4644) can help you contact a local hair loss support group, and gather more information.)

STEP 2. ENGAGE THE ENERGY

Homeopathic remedies for women with hair loss include:

  • Lycopodium: loss precipitated by hormonal fluctuations.


  • Sepia especially for menopausal women who have sweaty flushes and heavy bleeding


  • Phosphoric acid: loss after grief or extreme emotion, accompanied by exhaustion.

STEP 3. NOURISH AND TONIFY

  • Infusion of stinging nettle, 2-4 cups a day, strengthens hair and checks falling hair with its superb supplies of protein, B vitamins, vitamin E, iron, and other minerals. Regular use restores thickness, body, shine and sheen to hair. If you have any infusion left over, pour it on your head and rub it into your scalp for faster results.

  • "Every grey hair represents a day with too few minerals," a wise woman said to me. Actually, the color of hair is produced by special cells which gradually die as we age. But it is true that hair is loaded with minerals, and getting extra minerals may keep those color cells alive longer. To increase my mineral intake, and keep my hair healthy, I eat more yogurt, drink more nourishing herbal infusions, prepare more mineral-rich soups, use more herbal vinegars, and increase the amount of seaweed in my diet.

  • Lack of minerals, especially iron, can cause hair loss. Yellow dock is one of my favorite iron-tonics.

  • Natural hair dyes can cure the grey blahs. Henna (Lawsonia inermis) is a plant that is easily purchased ready-to-use to change the color of your hair, and you are not limited to carrot-top red. So long as it is not overused (less than four times a year) henna is strengthening to the scalp and hair.

    Other natural hair dyes include coffee, black walnut hulls, or infusions of sage or rosemary herb.

  • Herbalist Amanda McQuade Crawford suggests using lemon balm or lemon grass infusion as a hair rinse to prevent hair loss.

  • Burdock seed oil, one of the best selling hair tonics in Russia, is especially recommended for those with thinning hair or hair loss. Apply to your hair and scalp, leave on overnight and shampoo it out the following day. Repeat as needed.

  • Just plain olive oil is also a tremendous hair tonic. So is jojoba oil. Apply a handful of either to hair and scalp, wrap well and leave on overnight, washing it out the next morning.

  • I know you know, but let me say it again, exercise! Yes, it can make your hair healthier too.

STEP 4. SEDATE/STIMULATE

  • While some temporary loss of hair at menopause is considered normal, something worse may be brewing. Thin, dry hair is one of the first signs of an underactive thyroid. Hair loss is also an early sign of lupus, an autoimmune disease.

    Chugging down a gulp of cod liver oil or wheat germ oil every day for six weeks could help your hair.

  • Menopause sends lots of energy to the crown of your head. That can overstimulate the scalp and cause hair loss (and/or headaches). Get your energy moving with a scalp massage. Let your head calm down and your hair cool off.

  • Blow dryers, dyes, perms, and other harsh treatments damage hair and scalp. Rosemary essential oil, a few drops rubbed into the scalp several times a week, repairs the damage, increases hair growth, and improves hair texture.

    Other essential oils which improve hair growth and reduce hair loss include lavender oil, lemon oil, thyme oil, sage oil, and carrot seed oil. You can mix 10-20 drops of any of these into 4 ounces of plain olive oil, infused burdock seed oil, or jojoba oil. Other essential oils said to reduce hair loss include birch, calendula, chamomile, cypress, rose, and yarrow.

  • Avoid chlorinated water on your hair. A shower filter is more important than a drinking water filter. And cut down on the number of times you wash your hair. Once every 5-10 days is ideal for healthy hair.

  • Avoid cayenne. Heroic herbalists say it increases hair growth by improving blood circulation to the scalp. But when there is hair loss, says Janet Roberts MD, specialist in women's hair loss and member of the Oregon Menopause Network, there are inflamed follicles. Cayenne increases inflammation, ultimately increasing hair loss.

STEP 5A. USE SUPPLEMENTS

  • Dry, brittle, thin hair is often due to a deficiency in one or more of these nutrients: protein, vitamin A, vitamin B12, vitamin C, iron, zinc, essential fatty acids. Food and herbal sources of these nutrients are preferable to pills.

  • Avoid hair weaving, a cosmetic treatment that weaves replacement hair in with the still existing hair; it actually causes more loss (by creating traction alopecia).

STEP 5B. USE DRUGS

  • Hair loss can be caused by drugs, including: birth control pills, anticoagulants, diet pills, thyroid medications; non-steroidal anti-inflammatory drugs including aspirin, ibuprofen, and Aleve; cholesterol-lowering drugs such as clofibrate and Gemfibrozil; arthritis medications such as gold salts (auranofin), indomethacin, naproxen, sulindac, and methotrexate; beta-blockers such as atenolol (Tenormin), metoprolol (Lopressor), nadolol (Corgard), propranolol (Inderal), and timolol (Blocadren); and ulcer drugs such as cimetidine (Tagamet), ranitidine (Zantac), and famoridine (Pepcid). And, of course, chemotherapy.

  • Minoxidil (Rograine) dilates blood vessels, encouraging baby-fine hair. Only the 2% solution is approved for women. Of those who use it only 19% achieve even moderate regrowth; 40% have minimal regrowth. Meanwhile, 40% of the women using the placebo had regrowth! CAUTION: Side effects in women include unwanted hair growth on the face, heart disturbances, and dizziness.

  • Fertile women are not allowed to use (or even touch) finasteride (Propecia) for fear of the severe birth defects it causes. This is probably a blessing in disguise, as the side-effects (loss of libido, lip swelling, breast engorgement, birth defects) are not pleasant. Finasteride is completely ineffective in reversing hair loss for postmenopausal women. Tell your men friends a dose of 0.2 mg (one-fifth the normal dose) works just as well, costs less ($10 a month instead of $50), and is gentler on the liver.

  • Hormones, including ERT, HRT, birth control pills, and anti-androgens (cypoterone acetate, spironolactone, and fluramide) are used singly or in combination to treat women with androgenic alopecia.

STEP 6. BREAK AND ENTER

  • Hair transplants can cover a bald spot but are far less successful on women than on men. Micrografts do a better job of dealing with women's diffuse pattern of hair loss.

  • "Scalp lifts" tighten the scalp, making hair appear thicker and fuller.

HIRSUTISM/TOO MUCH HAIR

STEP 0. DO NOTHING

A few brazen souls just grin and bear it. Seriously, does anyone else notice that extra hair? Ask a few people who will tell you the truth. Perhaps you are making a mountain (beard/moustache) out of a molehill (a couple of extra hairs)?

STEP 1. COLLECT INFORMATION

It is not at all unusual to find extra hairs growing on the chin, upper lip, breasts, and legs during or after menopause. It is thought that menopause makes some hair follicles more sensitive to Testosterone's hair-promoting effects. However, sudden hair growth can be caused by a tumor on the ovaries, thyroid, adrenals, or pituitary.

STEP 2. ENGAGE THE ENERGY

Visualize a large mirror. Look at yourself in this mirror. When you see something you don't like, ask the mirror how you can change. Finish by telling your image how much you love her. Repeat frequently.

STEP 3. NOURISH AND TONIFY

Oatstraw infusion tends to increase the activity of Testosterone; increased levels of Testosterone contribute to excess hair growth during menopause. It's a long shot, but avoiding oats, oatmeal, and oatstraw infusion may help eliminate or reduce those extra hairs.

STEP 4. SEDATE/STIMULATE

  • Natural bleaches, like lemon juice or sunlight (or both together), are generally safe even for use on the sensitive skin of the face.

  • Shaving, plucking, and waxing are minimally invasive means of removing excess hair. Such means may increase the rate of hair growth, however, or make the texture of the hair coarser, or cause hair follicle inflammation and ingrown hairs.

STEP 5B. USE DRUGS

  • Hirsutism may be caused by corticosteroids and medications for high blood pressure. (Rograine was originally a blood pressure drug.)

  • Drug treatments - which are 80% successful according to one MD - include the corticosteroids prednisone and dexamethasone. Hormones, including birth-control pills and anti-androgens such as spironolactone, are occasionally used.

STEP 6. BREAK AND ENTER

Electrolysis is expensive, painful, tedious, must be done several times over, and can cause scarring. Most sources advise against home electrolysis.

Cholesterol- Getting Down to the Basics

Blood cholesterol levels have been proven to be a major, modifiable risk factor for the development of heart disease. A risk factor is a condition that increases your chance of getting a disease. The fact that high cholesterol is a modifiable risk factor is important. Unlike your gender or your age, the cholesterol level in your blood is something you have the ability to change. High cholesterol levels can be treated with lifestyle modifications, supplements and/or prescription medication. Treatment to change blood cholesterol levels have been shown to lower your risk of getting heart disease or having a heart attack or stroke.

Cholesterol builds up in the walls of your arteries. Over time, this buildup causes "hardening of the arteries" so that arteries become narrowed and blood flow to the heart is slowed down or blocked. You can imagine what that looks like if you think about the pipes under your kitchen sink. As they get clogged with food, grease and hair over time, the drainage of water slows and eventually stops completely. Since blood travels through these arteries, or pipes, to carry oxygen to your muscles, organs and tissues including your heart, a blockage could reduce enough blood and oxygen to your heart that you may suffer chest pain, called angina. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack. If this blockage occurs in your brain, the result is a stroke.

High blood cholesterol itself does not cause symptoms; so there are a lot of people that are completely unaware that their cholesterol level is too high. It is important to find out what your cholesterol numbers are because lowering cholesterol levels that are too high lessens the risk for developing heart disease and reduces the chance of a heart attack or stroke. Even if you have already had a heart attack or stroke, lower cholesterol will reduce your chance of having second one. Cholesterol lowering is important for everyone--younger, middle age, and older adults; women and men; and people with or without heart disease.

There are different kinds of cholesterol in your blood that can measured through a simple blood test preformed at your doctor's office. This blood test must be preformed fasting, which means you can not eat or drink anything but water or black coffee for 8-12 hours before your blood test for them to be accurate.

What is LDL?

LDL (bad) cholesterol is the main source of buildup and blockage in the arteries. The majority of LDL is created by your body in your liver. A smaller percentage of it is absorbed through your diet. An easy way for patients to remember LDL is the "bad cholesterol" is to think the L in LDL stands for Lousy cholesterol, or the one you want to Lower.With this form of cholesterol, studies have shown the lower the better. Babies are born with an LDL of 30-40, so it is hard to lower the LDL too much. Since physicians and various guidelines have different goals for different patients, ask your doctor what your personal goal is for LDL.

What is HDL?

HDL (good) cholesterol helps keep bad cholesterol from building up in the arteries. An easy way for patients to remember this is the good cholesterol is the H in HDL stands for Healthy cholesterol or the one you want to be Higher. Studies show that with this form of cholesterol, the higher the better. If your HDL is below 40, it becomes an additional risk factor for heart disease. If your HDL is above 60, it actually allows you to subtract one of your other risk factors.

What Is Triglicerides?

Triglycerides are another form of fat in your blood which is often high in patients with diabetes, but can be high in anyone. Some patients may only have high triglycerides while all other cholesterol values remain normal. If you have both high triglycerides and high cholesterol, the condition is called "mixed dyslipidemia".

What Does Total Cholesterol To HDL Ratio Mean?

Another number that clinical studies have shown to be important in determining your risk of heart disease is the ratio of Total Cholesterol to HDL Cholesterol. In general, it should be less than 4.0. Ask your doctor what your value is, and what your specific goal should be. Again this is a number where the lower it is, the better.

The level of your LDL or "bad cholesterol " along with the number of other risk factors that you may have for developing heart disease will help your doctor decide not only your individual cholesterol goals, but if necessary what your individual treatment will include.Other risk factors for heart disease include age, gender (males), cigarette smoking, high blood pressure, diabetes, HDL levels below 40, and a family history of early heart disease. Even though physical activity (sedentary lifestyle) and obesity are not included on this list, these are conditions that need to be corrected as well.

There are several treatment options for patients depending on individual test results and goals. All treatments should include a diet designed to lower cholesterol intake and an exercise plan. Many treatment plans will include dietary supplements and/or prescription medication(s). There are a variety of prescription medications that can target your specific treatment needs, including but not limited to lowering the amount of LDL created by the liver, lowering the amount of LDL that is absorbed from your intestines, increasing levels of HDL or lowering levels of triglycerides.Your doctor may put you on one, or a variety of medications to meet your individual treatment goals.

Blood cholesterol levels have been proven to be a major, modifiable risk factor for the development of heart disease. A risk factor is a condition that increases your chance of getting a disease. A modifiable risk factor is something you have the ability to change. High cholesterol levels can be treated with lifestyle modifications, supplement and/or prescription medication. Treatment to change blood cholesterol levels have been shown to lower your risk of getting heart disease or having a heart attack or stroke.

There are many different types of cholesterol lowering medications that your doctor may prescribe, however these prescriptions can cause certain nutritional deficiencies that may increase your risk for side effects or diminish the risk reduction you would otherwise get from the cholesterol lowering medications. NutraMD Cholesterol Essential Nutrients(R) supplement was designed to work with your cholesterol lowering medications by replacing lost nutrients reducing the risk of dangerous side effects, and promote better health.

Medications for treatment of High Cholesterol:

The three main classes include statins, fibrates, and bile acid sequestrants.

Statins include the following medications:


Lipitor (Atorvastatin)


Zocor (simvastatin)


Pravachol (pravastatin).


Mevacor (lovastatin)


Crestor (rosuvastatin)


Advicor (lovastatin + niacin).


Caduet (Atorvastatin + amlodipine).

The main function of statins is to reduce an individual��s risk for cardiovascular disease (i.e., heart attack, stroke, peripheral vascular disease, atherosclerosis, arteriosclerosis, and plaque development in arteries) by reducing the total and LDL cholesterol levels as well as by reducing certain plaque promoting factors and increasing artery dilating factors.Your doctor may prescribe a statin if you have high cholesterol or have had heart attack or stroke in the past. If you have been diagnosed with high blood pressure or diabetes but do not have high cholesterol, your doctor may still prescribe a statin to reduce your risk for cardiovascular disease. Statins help lower cholesterol by blocking it's direct synthesis throughout the body but primarily in the liver, however the action of the medication also blocks the synthesis of Coenzyme Q10 (CoQ10) and has a potential negative effect on the synthesis of vitamin D.

* CoQ10 deficiency has been linked to the following diseases and symptoms:

Congestive heart failure, high blood pressure, rhabdomyolysis (muscle break down), muscle and joint pain, and fatigue.

Therefore to achieve maximum benefit from the statin medication and minimize potential side effects of nutrient deficiencies, you should compliment your prescription medication by taking NutraMD Cholesterol Essential Nutrients(R) supplement. By doing this you will balance the risk/benefit ratio further in your favor.

Fibrates include the following medications:

Tricor, Antara, and Lofibra (fenofibrates)


Lopid (Gemfibrozil).

The main functions of fibrates are to lower triglycerides and raise HDL (good cholesterol). These medicines also have a mild lowering effect on LDL (bad cholesterol) and total cholesterol. Your doctor may prescribe fibrates in combination with a statin or bile acid sequestrants. The down side of fibrates is there ability to increase muscle pain and myalgia (including rhabdomyolysis).11-15 These medications also have the ability to raise homocysteine levels.11-15 Homocysteine is a chemical (amino acid metabolite) which when elevated is a risk factor for heart disease, atherosclerosis, stroke, cancer, Alzheimer's disease, and osteoporosis. The only substances known to lower homocysteine levels are the B-vitamins (folate, riboflavin, cobalamin, and pyridoxine).Therefore to reduce the potential risks while taking fibrates, you should also be taking NutraMD Cholesterol Essential Nutrients(R) supplement.

Bile Acid Sequestrants include the following medications:

Questran or Questran Light (cholestyramine)


Welchol (colesevelam HCl).

The main functions of bile acid sequestrants are to lower cholesterol by binding to it in the intestine and preventing its absorption thus allowing its excretion in the feces. Your doctor may prescribe this type of medicine in combination with fibrates and statins. Unfortunately, bile acid sequestrants will also bind to vitamins A, D, E, and K as well as essential fats in the intestine preventing their absorption into the blood stream thus leading to their deficiencies. A few of the problems which arise from deficiencies of vitamins A, D, E, K, and essential fatty acids include the following: Heart disease, high cholesterol, stroke, high triglycerides, cancer, thyroid disease, autoimmune disease, bone disease, arthritis, joint pain, muscle pain, cataracts, skin lesions, allergies, and many other.Therefore, to reduce potential side effects of nutrient deficiencies you should take NutraMD Cholesterol Essential Nutrients(R) supplement as long as you are on bile acid sequestrants.

In summary, cholesterol-lowering medications prescribed by your doctor are necessary to treat your condition; however, you should also be aware that the long term potential nutritional side effects can be just as big a risk factor for your condition as well as other conditions. Put the odds in your favor and maintain your health with NutraMD Cholesterol Essential Nutrients(R) supplement.

High Cholesterol Level: Risk Factors, Treatment Options

What is cholesterol?

Cholesterol is a type of fat (lipid) made by the body. About 80% of cholesterol is made by the body, the other 20% comes from the diet. Cholesterol is a building block for cell membranes. Our body uses cholesterol to produce many hormones (e.g., progesterone, estrogen, Testosterone), vitamin D, and the bile acids that help to digest fat.

Many foods contain cholesterol and high intake of these foods can increase the level of cholesterol in the blood. Having too much cholesterol in the blood is not a disease in itself, but high cholesterol (hypercholesterolemia) can cause the formation and accumulation of plaque deposits in the arteries. Plaque is composed of cholesterol, other fatty substances, fibrous tissue, and calcium. When it builds up in the arteries, it results in the hardening and narrowing of the arteries (atherosclerosis) in the major vascular systems.

Narrowing of the arteries around the heart (coronary heart disease) can prevent the heart from getting as much oxygen-rich blood as it needs, increasing the risk of a heart attack. Decreased blood flow to the brain can cause a stroke, and less blood flowing to the lower limbs may result in exercise-related pain or even gangrene.

Having a high cholesterol level does not cause symptoms and does not make you feel sick. If there is a huge excess, some people develop soft, yellowish skin growths called xanthomas, usually in the area near the eyes. Most people find out they have high cholesterol when they have their blood cholesterol measured as part of a medical check-up.

Types of Cholesterol

Cholesterol is not soluble in water and doesn't mix easily with blood. In order to be able to travel in the bloodstream, the cholesterol made in the liver is combined with protein and other substances. This cholesterol-protein package is called a lipoprotein. Lipoprotein then carries the cholesterol through the bloodstream.

Lipoproteins can be high density (HDL), low density (LDL) or very low density (VLDL), depending on how much protein there is in relation to fat.

LDL (low density lipoprotein)

Low-density lipoprotein (LDL) is called the "bad" cholesterol. About 70% of cholesterol is transported as LDL. This is mostly fat and not much protein. LDL causes cholesterol to be deposited in the arteries. High levels of LDL are associated with an increased risk of coronary heart disease.

HDL (high density lipoprotein)

High-density lipoprotein (HDL) is called the "good" cholesterol. It carries cholesterol from the body's tissues back to the liver. About 20% of cholesterol is transported as HDL, which is mostly protein and not much fat. HDL cholesterol may help protect against atherosclerosis by preventing cholesterol from depositing on arterial walls as it circulates in the bloodstream.

Risks factors

There are several factors that may contribute to high cholesterol level in the blood:



  • Genetic predisposition. People are at a higher risk of high cholesterol if they have a direct male relative aged under 55 or female relative aged under 65 affected by coronary heart disease.


  • Diet high in saturated fat. Saturated fat and cholesterol come from animal foods such as beef, pork, veal, milk, eggs, butter, and cheese.


  • Sedentary lifestyle. Lack of exercise may increase LDL cholesterol and decrease HDL cholesterol. Regular physical activity may lower triglycerides and raise HDL cholesterol levels.


  • Overweight. Excess weight may modestly increase your LDL (bad) cholesterol level.


  • Age and sex. Cholesterol generally rises slightly with increasing age, and men are more likely to be affected than women.


  • Drinking alcohol excessively. Drinking too much alcohol can damage the liver and heart muscle.


  • Diabetes. Diabetes is a significant risk factor for all cardiovascular diseases.


  • Smoking. This applies not only if you smoke, but also if you live or work every day with people who smoke.


Treatment options

Lifestyle changes such as changing diet, managing weight, increasing exercise, and quitting smoking are the first steps to improving blood levels of cholesterol. If these changes are not enough, your physician might recommend cholesterol-lowering prescription medication.

Medications to improve blood cholesterol levels include:



  • Statins - are the most widely used, and also the most powerful medications for lowering LDL cholesterol. They work by reducing the production of cholesterol in the liver. Statins not only lower blood LDL cholesterol levels, they also modestly increase HDL cholesterol levels and modestly decrease triglyceride levels. These medications are usually well tolerated, have few side effects, and are taken once or twice a day. Currently, six statin drugs are available: Atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and rosuvastatin (Crestor).


  • Bile acid sequestrants - these drugs bind with cholesterol-containing bile acids in the intestines and are then eliminated in the stool. They typically lower cholesterol by 10 to 20%. Small doses of sequestrants can produce useful reductions in LDL cholesterol. Cholestyramine (Questran, Questran Light), colestipol (Colestid), and colesevelam (WelChol) are the 3 main bile acid sequestrants currently available. Bile acid resins are mainly used in young adults with hypercholesterolemia or in combination with another cholesterol-lowering medication.


  • Cholesterol absorption inhibitors - are a new class of cholesterol lowering agents approved in 2002. Drugs in this class work to lower blood cholesterol levels by absorbing excess cholesterol in the intestines and thus blocking cholesterol's entry into the bloodstream. Ezetimibe (Zetia) is the first drug in this class. Ezetimibe reduces LDL cholesterol by 18-20%. It is probably most useful in people who cannot take statins or as an additional drug for people who take statins but who notice side effects when the statin dose is increased. Adding ezetimibe to a statin is equivalent to doubling or tripling the statin dose.


  • Nicotinic acid or niacin - this water-soluble B vitamin improves all lipoproteins when given in doses well above the vitamin requirement. Nicotinic acid lowers total cholesterol, LDL cholesterol, and triglyceride levels, while raising HDL cholesterol levels. Niacin also widens blood vessels, making flushing and hot flashes frequent side effects.


  • Fibrates - these cholesterol-lowering drugs are primarily effective in lowering triglycerides and, to a lesser extent, increasing HDL cholesterol levels. These drugs include fenofibrate (Tricor) and Gemfibrozil (Lopid).

Ultimate Guide To Avoiding Hair Loss

Hair loss (Androgenetic alopecia) refers to the reason of hair loss that is influenced by the androgen hormone, the genetic tendency for balding and aging. Because hair loss is caused by these hormones, treatment is available to immediately and dramatically prevent the loss of hair.

Androgenic Hormones

In general, normal men including women make male hormones. Testosterone, underestimation, and dihydroTestosterone (DHT), are the most common that they produce. Androgens are manufactured by the men's adrenals and testicles, and in women, by their adrenal glands and ovaries. In both sexes, these hormones are important but take place in different concentrations and amounts.

When hair follicles are exposed to DHT, a genetically prone individual, over time, leads to androgenetic alopecia, or female and male pattern baldness.

In particular cells of the hair follicle, as with in the sebaceous glands, there are enzymes called 5-alpha-reductase that are in high levels, converting Testosterone which is then carried to these areas by the blood, and into DHT.

Hair loss myths:

Myth #1: Hair loss of an individual is inherited from the mother side.

Not true. Genetics is one factor of hair loss, it can be inherited from either the father's or the mother's side.

Myth #2. Frequent cutting of hair will make it grow thicker.

Not true. Although when the hair is cut, it would appear thicker at first, after three days or so, your hair would drop off and new hair would grow, having the same diameter as the pre cut hair.

Myth #3. Wearing a Hat Can Cause Hair Loss.

Not true. The hat can help by blocking off the sun's harmful rays. Although wearing a hat for a very long period of time may cause sebum accumulation due to temperature changes and can react with cholesterol creating a hardened sebum plug that will cut off oxygen circulation causing the hair to fall out.

Myth #4. DHT is the reason for hair loss.

Not true. Although an over production of DHT is a significant reason for hair loss, it is not the only cause.

Myth #5. Frequent shampooing and blow drying lead to hair loss.

Not true. Heat can damage the hair, reason for brittle hair; it does not harm the roots of the hair.

Even worse, some perscription drugs are known to cause hair loss. Avoid if at all possible the following drugs:

- Cholesterol-lowering drugs:

- clofibrate (Atromis-S)

- Gemfibrozil (Lopid)

- Antidepressants:

- tricyclics, amphetamines

- High blood pressure:

- atenolol (Tenormin)

- metoprolol (Lopressor)

- nadolol (Corgard)

- propranolol (Inderal)

- timolol (Blocadren)

- Antithyroid:

- carbimazole

- Iodine

- thiocyanate

- thiouracil

- Ulcer drugs:

- cimetidine (Tagamet)

- ranitidine (Zantac)

- famotidine (Pepcid)

- Anticoagulents:

- Coumarin

- Heparin

Actions you can take to prevent hair loss:

- Stop coloring or perming your hair very often for it can damage it

- Limit exposure of your hair to chlorine

- Avoid exaggerated brushing or combing wet hair

- Use a conditioner every after shampoo to make grooming manageable and easier

- Regulate heat exposure. Blow-drying, hot-curling and exposure to straightening irons may damage your hair over time

- Avoid medications that can lead hair loss such as Vitamin A, Testosterone products, beta blockers, certain antidepressants and certain cholesterol-lowering agents

- Too much alcohol should be avoided. Be careful in choosing your hair care products as some contain alcohol and can contribute to hair dryness, brittle and hair that is prone to breakage.

- Tight ponytails and braids can lead to hair damage

- Maintain a healthy diet, eating lots of fruits and vegetables and drinking enough water

- Birth control pills can contribute to hair loss

- Consult your doctor if should you notice abnormal hair loss, as certain medical conditions such as lupus or having polycystic ovaries, or hyperthyroidism can cause hair loss

Vitamins you can take to prevent hair loss:

- Thiamin ( B1)

Containing the mineral sulfur, this is the essential element of the hair that gives gloss and shine.

- Riboflavin (B2)

This vitamin is vital for body cell breathing, ensuring efficient oxygen utilization for cell repair and production.

- Niacin (B3)

Helps to widen capillaries and vessels thereby increasing the blood circulation to the scalp to help stimulate hair growth. It also may reduce the cholesterol build up which is essential since cholesterol on the scalp will convert to the enzyme 5 alpha reductase.

- Pahtothenic Acid (B5)

This vitamin helps in restoring hair color and brightness. It works with the amino acid Tyrosine Folic Acid, PABA and Copper in the deterrence white and gray hair.

- Biotin (B7)

Biotin is a widely used ingredient in hair products due to its hair promoting properties. Biotin increases hair cortex elasticity , prevents breakage, and thickens hair cuticle.

- Cobalamin (B12)

Regenerates red blood cells for healthy hair.

- Pyridoxine (B6).

Responsible for protein intake balance, it helps in transporting amino acids to the proper tissues. This is also essential in the conversion of one amino acid to another like the conversion of Methionine to Cysteine. With Inositol, they regulate oil flow to the scalp and the skin.

Why People Become Bald

Are you becoming bald? Don't panic. It's not the end of the world yet. Before you blame your barber or hairdresser, try to find the cause of your problem.

Baldness can either be temporary or permanent. Temporary hair loss can occur one to three months after a high fever or severe infection. It may follow surgery or radiation treatment. Some women lose large amounts of hair within two to three months after giving birth when many hair follicles enter the resting phase of the hair cycle. However, not all new mothers will experience this nor does hair loss occur with each delivery.

In others, baldness is caused by an underlying condition like an overactive or underactive thyroid, syphilis or systemic lupus erythematosus. Obese people who go on crash diets, malnourished individuals, and those suffering from a protein or iron deficiency may also experience hair loss. In these people, hair can easily be pulled out by the roots.

"What you eat - or don't eat - may be the reason why you're losing hair, especially if your diet is deficient in iron or protein. Dietary iron and iron metabolism are especially important in a woman's hair cycle. Often women who crash diet or who have eating disorders like bulimia or anorexia nervosa suffer from hair loss," according to the editors of "The Women's Book of Home Remedies" published by Consumer Guide.

Certain medications can cause hair to become thin and break off. These include cancer drugs, blood thinners, aspirin, steroids, blood pressure medications, antidepressants, herbal medicines, and vitamin supplements, especially high doses of vitamin A or D or selenium.

"Hair loss may be related to taking a wide range of medications or herbs with heavy metals in them. Chemotherapy drugs, of course, are notorious for causing hair to fall out, but more common drugs like some cholesterol-lowering drugs (clofibrate, Gemfibrozil), most arthritis medications, beta-blocking drugs for high blood pressure, and some ulcer drugs can also cause distressing hair loss," said the editors of "The Women's Book of Home Remedies."

Excessive hair care and over-styling are other causes of temporary baldness. Tight ponytails, a sharp comb or brush, and hand curlers can make your hair thin and ugly. The same goes with bleaching, teasing, and straightening if they're not done right or if they are done too frequently. As Dr. Fredric Haberman of the Albert Einstein College of Medicine and Denise Fortino point out in "Your Skin: A Dermatologist's Guide to a Lifetime of Beauty and Health":

"Paradoxically, paying too much attention to your hair may also increase your chances of losing it. Coloring, straightening, drying, frequent shampooing, brushing or conditioning, using tight curlers or clasps, or repeated pulling and twisting can be bad for your hair. Cold wave solutions without a built-in neutralizer can have a depilatory (hair-removing) effect if they are left on too long."

"Forget the 100 brush strokes at night, too. The less you do to your scalp and hair, the better. If you can't give up those styling treatments, at least try to space them out to reduce the trauma," added the editors of "The Women's Book of Home Remedies."

In others, hair loss may be a reaction to severe psychological stress. This may happen one to three months after a stressful situation. So if you've been under too much pressure lately, don't be surprised if your hair falls out.

If baldness takes the form of hairless patches that resemble a quarter or larger, you probably have alopecia areata. This is characterized by circular bald patches and affects about two percent of the population. Its cause is unknown and it may involve the entire scalp (alopecia totalis) or the whole body (alopecia universalis).

Baldness can make you look older so take good care of your hair. To preserve your youthful looks, use Dermaxin, a popular skin cream that contains special ingredients to reduce fine lines and wrinkles by as much as 45 percent. Dermaxin repairs and rejuvenates the skin so you'll look young, fresh, and wrinkle-free! It's your best defense against the signs of aging. For details, visit http://www.dermaxin.com.
