Hormone Replacement Therapy
Hormone Replacement Therapy
Essentially, hormone replacement therapy is the substitution of an exogenous hormone when there is a deficiency state. Most commonly, hormone replacement therapy refers to the use of female hormones to ease the transition of menopause, due to either surgery or the natural aging process, as well as to reduce post-menopausal health risks, notably osteoporosis.
Hormone replacement therapy (HRT) has existed in some form for more than a century. Examples include: insulin, thyroid and corticosteroids.
Estrogen became available about fifty years ago although initial therapies with diethylstilbestrol (DES) may have had a negative impact upon the health of generations of children and their families. Both sons and daughters of women who took DES (usually to overcome a problem of infertility) have genital disorders and daughters have an increased susceptibility to cancer of their reproductive organs.
More recently, two forms of treatment have reached prominence: ERT (estrogen replacement therapy) and HRT.
ERT uses lower doses of estrogen and will generally be used for women who have undergone surgical menopause. The major benefit sought is to decrease complications of osteoporosis, namely hip and spine fractures.
For women who go through menopause, naturally, there is some concern that estrogen, by itself, will overstimulate the uterine lining, possibly causing endometrial hyperplasia which might lead to uterine cancer. Consequently, estrogen must be combined with progesterone. HRT, therefore, combines estrogen and progesterone.
In describing hormone replacement therapy (HRT), it was accepted that menopause is followed by a deficiency of female hormones.
Surgical procedures may remove the uterus and ovaries, or the ovaries can cease to function, naturally. There is some debate whether being menopausal requires the replacement of estrogen because there is a true deficiency.
There are arguments on both sides of this issue. Some women are happy to avoid many of the distressing symptoms associated with their "change of life" (the climacteric) and gain some immunity from long term consequences, notably osteoporosis.
However, other women are alarmed at now being subjected to hormonal drugs for most of their whole lives, either to protect them against conception, or against the ravages of time. Are women being betrayed by their natural hormonal cycles? Are women being exploited by doctors and the pharmaceutical industry?
Signs & Symptoms
The classic sign of menopause is the cessation of menstruation which usually takes place before 55 years of age, In Western countries a host of symptoms are now reported by the majority of women during this stage of their lives, including: 'crawly' skin sensations, depression, dizziness, fatigue, 'hot flashes' or 'flushes' (episodes of sudden skin flushing and perspiration in 70% of women, lasting between 1 and 5 years), insomnia, irritability, shortness of breath, strange pains and vaginal dryness.
These symptoms aren't serious, by themselves but certainly uncomfortable, even incapacitating. Of greater significance are the loss of bone mass and changes in the heart and blood vessels, both of which have high morbidity and mortality rates.
HRT has the potential to alleviate and, in many cases, eliminate these symptoms, as well as reducing the progression of the chronic diseases.
Estrogen improves the condition of the vagina and decreases the risk of heart disease and strokes. Overall, women taking HRT live longer than women who do not.
ERT may also play a role in the prevention of senile dementia.
On the other hand, HRT can increase breast density, making it more difficult to diagnose breast cancer by mammography. Some references report an increased incidence of breast and endometrial cancer in HRT populations studied. A recent study has reported a 2.5-fold increase in gallbladder disease in ERT populations.
There is also some breakthrough bleeding but most women have preferred to deal with this inconvenience than forego the other benefits.
Unraveling the precise risks and benefits for each woman is quite a complex issue for patients and their physicians. In an attempt to shed some light upon this, one study interviewed women physicians. In Britain, where this study was undertaken, the average use of HRT is quite low (1 5%) in the general population but increases within the younger set of postmenopausal women physicians to around 60%. The American rate is around one-third of all eligible women.
Some definite contraindications to HRT have also been established, including: acute liver disease, breast or cervical cancer, fluid retention, high blood fats, phlebitis, or uncontrolled hypertension.

Note: All amounts are in addition to those supplements having a Recommended Dietary Allowance (RDA). Due to individual needs, one must always be aware of a possible undetermined effect when taking nutritional supplements. If any disturbances from the use of a particular supplement should occur, stop its use immediately and seek the care of a qualified health care professional.
Long term, continuous use of "the Pill" is also associated with expansive vitamin and mineral depletion, notably:
Biotin, Choline, Folic acid, pyridoxine (vitamin B6), Niacin (vitamin B3), Riboflavin (vitamin B2), Vitamin B12 and Vitamin C; as well as minerals: Calcium, Magnesium, Manganese and Zinc.
Since it is most likely that a woman who has been on "the Pill" would switch to HRT, the same depletions might be anticipated.
Additional risk factors among patients using oral contraceptives include: malabsorption states (e.g. gluten-sensitive enteropathy) and inflammatory bowel disease. [Roe, 1994] In which case, Vitamin K deficiency is quite high in individuals with chronic gastrointestinal disorders or poor fat absorption.

A healthful diet may provide a smoother menopausal transition. Indeed, the Japanese culture, apparently, has no term for "hot flash", which is credited to the predominance of phytoestrogens, notably in soy products.
Several foods may be contraindicated: notably caffeine, as well as highly spiced, or hot, foods. Alcohol should also be avoided and sugar, too, according to some authorities. Certainly, highly refined and sweetened processed products have little to contribute nutritionally.
Over-the-counter homeopathic remedies may be single strength (of fairly weak potency e.g. 6X ) or a blend of several weaker strengths (6X, 8X, 1 OX).
This may comprise a single remedy, or several remedies.
Doses are administered on a 3 times daily (tid), between meals,schedule and continued for 3 days.
Liquid preparations usually use 8-1 0 drops per dose.
Solid preparations are usually 2 or 3 pellets per dose.
Children use 1/2 dose i.e. 1 pellet.
If there is aggravation of the symptoms, stop taking the remedy and consult a homeopath.

Angelica (Dong Quai)
Chaste tree (berries)
Note: The misdirected use of an herb can produce severely adverse effects, especially in combination with prescription drugs. This Herbal information is for educational purposes and is not intended as a replacement for medical advice.
Phytoestrogens (also isoflavones) have not been associated with the side-effects of pharmaceutical preparations, usually synthetic hormones, derived from e.g. mare's urine. Licorice root, Red clover and Wild yam have been featured, while the accompanying list adds several more (although there are some 300 altogether).
Angelica (Dong Quai) is known as the "female ginseng", however, while Oriental women may not experience as many problems with menopause as their modern, Western counterparts, it has been found useful for "hot flashes".
Black cohosh is reputed to relieve hot flashes, insomnia and irritability. A Native American herb, the standardized extract has been in use in Germany since 1956 and this form is now gaining popularity in America. The Latin name is used: Cimicifuga racemosa, In 1994 over 6.5 million units were sold in Europe.
Chaste tree is deemed to be helpful to those who begin menopause early (in their early forties).
Horsetail is important for hair, nails and the skeleton as it is rich in silica.
