Female Menopause References
The term menopause refers to a decline in female hormones in women, often with a significant drop when in their 40s or 50s-including estrogens, progesterone and testosterone. Menopause is defined as no menstrual cycle for 12 months; yet "perimenopausal" symptoms may begin up to 10-15 years before true menopause. Every day in the United States, approximately 3,500 women begin menopause. Due to longer lifespans, many women can expect to spend 3 decades or longer in menopause.
Oral estrogens increase a protein called "CRP" (C-reactive protein), which is an independent risk factor for stroke, heart attacks, diabetes, blindness (due to macular degeneration) and certain cancers. Therefore it is not surprising that the "Premarin only" arm of the Women’s Health Initiative study published in April 2004 in the Journal of the American Medical Association revealed a significant increase in stroke risk. Bio-identical (same type that exists in women) estrogen (estradiol) cream applied on the skin does not increase CRP.
Oral horse estrogen (conjugated equine estrogen, Premarin) has estrogens that are natural to horses, but unnatural to humans, because they are not “bio-identical” to the estrogens found in women. Therefore it is not surprising that these foreign hormones ("equilin" "equilenin") lead to unwanted symptoms and effects. PRE-MAR-IN is derived from the PREgnant MARe urINe. Bio-identical estrogen (estradiol) applied on the skin, in the correct dose, and when balanced with the correct dose of bio-identical progesterone avoids most, if not all, of unwanted side effects from Premarin.
Oral estrogens decrease blood levels of IGF-1, an active form of natural Growth Hormone that your own body makes. IGF-1 is involved in helping to maintain muscle and bone mass, while decreasing fat mass. Bio-identical estrogen (estradiol) cream applied on the skin does not decrease IGF-1 levels.
Oral estrogens decrease the level of free testosterone, due to an increase in a protein made by the liver called "sex hormone binding globulin." Women normally have some testosterone (more abundant in men), which helps maintain libido (interest in sex), helps the intensity of orgasms, helps maintain muscle and bone mass, and has a number of beneficial mental benefits. Bio-identical estrogen (estradiol) cream applied on the skin does not affect levels of testosterone or sex hormone binding globulin.
Oral equine estrogen increases fat mass and decreases muscle mass. Bio-identical estrogen (estradiol) cream applied on the skin does not increase fat mass and does not decrease muscle mass.
Oral estrogens increase blood clotting factors, a risk for abnormal clotting and therefore increase the risk for heart attack, stroke and possibly dementia (decline in brain function) and Alzheimer’s disease. Bio-identical estrogen (estradiol) does not significantly increase these factors.
Oral estrogens increase blood pressure, the risk of gallstones and sometimes abnormally increase liver enzymes in the blood. Bio-identical estrogen (estradiol) does not have these effects.
Taking into account all these factors, it is no wonder that Premarin prescriptions in the US have plunged by almost half between 1999 and 2003!
The common synthetic progesterone MPA (medroxyprogesterone acetate) is called Provera and is combined with Premarin to make a 2-drug pill called PremPro. MPA is associated with a number of bad health outcomes, as demonstrated by the results of the PremPro arm of the Women’s Health Initiative (WHI) Study. While the Premarin only arm had an increased risk of stroke and a mild increased risk (trend) of dementia (loss of brain function), the PremPro arm had a significant increased risk of stroke, heart attack, breast cancer, blood clots in the lungs, and (for those older than 65 years) dementia. Therefore, adding MPA (synthetic progesterone) to Premarin (horse estrogen) led to a number of bad health outcomes that did not occur with Premarin alone. No wonder PremPro prescription sales in the U.S. have plummeted by 75% from 1999 to 2003! (The drugs are not necessarily all bad, since both arms showed a significant decrease in colon cancer and hip and other bone fractures). Before the WHI study, MPA has been shown to have several adverse effects on body functions and measurements, including in the heart, other blood vessels and in the brain. On the other hand, natural, bio-identical progesterone is not associated with these same negative effects that MPA has. Bio-identical progesterone balances out some of the effects of estradiol, just as what happens to normal, healthy women in the 20s and 30s (who are not taking oral contraceptives). The benefits are in the brain, heart, breast and possibly other organs at risk of developing cancer. Note that MPA and bio-identical progesterone each have beneficial effects for balancing estrogen in the uterus (womb).
Every woman’s body is unique and different. Therefore the specific dosing of hormones to be replaced is different for each and every woman during menopause and "perimenopause." Part of this is due to genetic factors, body shape differences, nutrition (diet), lifestyle factors, other medical conditions, and other medications. In addition, over time, a woman’s hormonal needs may shift, necessitating a modulation in hormone dosing. Thus, monitoring of the hormone levels in body fluids regularly is important. Testing frequency may be decreased after a woman is completely stabilized. In summary, menopause is different for each woman and approaches to treating menopause must be individualized.
Estrone is one of three main types of estrogens in women. It is weaker than estradiol, and it comes in several forms. The beneficial "2-hydroxy" estrone is the good type, while the "16-hydroxy" and "4-hydroxy" are associated with cancer-inducing effects. Part of balanced hormone replacement therapy includes treatments and approaches to maximize the "2", while minimizing the "16" and "4."Estradiol is the strongest of the 3 major estrogen types. Interestingly, estradiol can be converted to estrone in the body and vice versa.
Estriol is the weakest of the three major estrogen types. There is good evidence in the medical literature that it has some anti-cancer benefits, particularly in the breast. It is also very good in treating the "hot flashes," other "vasomotor" symptoms of menopause, vaginal dryness, and recurrent urinary bladder infections that may occur.
There are a number of studies that had shown that estrogen therapy was beneficial in delaying or avoiding Alzheimer's Disease (decline in brain function), cognitive (ability to understand) decline, and possibly memory loss. This is not too surprising, since there are numerous estrogen receptors in the brain-they must be there for a reason. Also estrogen decreases the production of amyloid beta proteins (occur in Alzheimer's) in brain nerve cells. In addition, estrogen increases the production of the enzyme "choline acetyltransferase" that makes the brain transmitter "acetylcholine." A-C (for short) deficiency is a major abnormal characteristic in the brains of people with Alzheimer's disease. (The first FDA-approved drugs to treat Alzheimer's all increase A-C.)
Yet both arms of the Women’s Health Initiative Study have shown some evidence of dementia or cognitive. This is likely associated with an increase in CRP (see above), due to the oral route of administration, and possibly due to other risk factors for brain decline, including elevated homocysteine, insulin resistance (pre-diabetes), high blood pressure, and increased body weight. Since topical (on the skin) estrogens due not increase CRP, that risk factor for brain decline would no longer be present. Preventive Neurology incorporates several strategies to avoid brain decline and illness at California Longevity and Vitality Medical Institute®. However, the beneficial aspects of estrogen on the brain can be achieved with the transdermal route, specifically, increasing choline acetyltransferase and decreasing amyloid deposits in the brain.
Most women will have a decline in their normal blood levels of androgen hormones (male-like effects) before or during the menopause. Many people are not aware that women have androgens, although at levels only 5-10% of that in men. (Similarly, men have estrogens and even progesterone!) As defined in the April 2004 supplement of Mayo Clinic Proceedings, symptoms of the Androgen Deficiency Syndrome in women include (not all are necessarily required for the diagnosis):
- Decreased libido (interest in sex), sexual receptivity and pleasure
- Low energy and persistent, unexplained fatigue
- Dysphoric (unhappy) mood
- Diminished psychological well-being
- Blunted motivation
- Decrease in bone mineral density
- Decreased muscle mass and strength
- Fat tissue redistribution (away from hips towards abdomen, trunk)
- Decreased pubic and armpit hair
- Changes in cognition (ability to comprehend) or memory
Note that some of these are non-specific, meaning they might be due to other causes or some may have several underlying causes.
A blood test would usually reveal a low "bioavailable" (not tightly bound to protein) or free testosterone. Other androgens include DHEA (dehydroepiandrosterone, from the adrenal glands), DHT (dihydrotestosterone, converted from testosterone) and androstenedione.
Common symptoms of low estrogen include: fatigue, low energy, lack of stamina, lack of sexual drive, painful intercourse, depression, hot flushes, sweats, menstrual irregularities or lack (no or poor menstrual blood loss), headaches, lack of resistance to physical efforts, increase in urinary bladder infections, urinary loss with straining, coughing or laughing (stress incontinence), increase in vaginal infections, hair/skin changes, new hair on face, breast changes, possible weight change, and possible joint aches. Note that some of these are non-specific, meaning they might be due to other causes other than female menopause.
Common symptoms of low progesterone include: nervousness, superficial and restless sleep, anxiety, irritability, excessive emotions, painful or swollen breasts (often before menstrual flow), swelling in hands, feet and sometimes in abdomen area, excessive menstruation, headaches, and possible weight change. Note that some of these are non-specific, meaning they might be due to other causes.
