menopause

 
 

Definition

Menopause represents the end of menstruation. While technically it refers to the final period, it is not an abrupt event, but a gradual process. Menopause is not a disease that needs to be cured, but a natural life-stage transition. However, women have to make important decisions about "treatment," including the use of hormone replacement therapy (HRT).

Description

Many women have irregular periods and other problems of "pre-menopause" for years. It's not easy to predict when menopause begins, although doctors agree it is complete when a woman has not had a period for a year. Eight out of every 100 women stop menstruating before age 40. At the other end of the spectrum, five out of every 100 continue to have periods until they are almost 60. The average age of menopause is 51.

There's no mathematical formula to figure out when the ovaries will begin to scale back either, but a woman can get a general idea based on her family history, body type, and lifestyle. Women who began menstruating early will not necessarily stop having periods early as well. It is true that a woman will likely enter menopause at about the same age as her mother. Menopause may occur later than average among smokers.

Dictionary: men·o·pause   (mĕn'ə-pôz') pronunciation
Top
n.

The period marked by the natural and permanent cessation of menstruation, occurring usually between the ages of 45 and 55.

[New Latin mēnopausis : MENO– + Greek pausis, pause; see pause.]

menopausal men'o·paus'al adj.
 
Sci-Tech Encyclopedia: Menopause
Top

The irreversible cessation of regular monthly uterine bleeding in the adult human female, marking the end of her ability to become pregnant. Menopause commonly occurs in the United States between the ages of 47 and 53. It probably occurs because the ovary runs out of eggs and the cyclic rise and fall of brain and ovarian hormones designed to prepare the uterus to receive and nourish pregnancy no longer occur.

Menopause is one event in the climacteric, the period of time during which the reproductive machinery slows down and finally stops. The biochemical hallmark of this period is a reduction in estrogen production by the ovary. Some estrogen continues to be produced by the adrenal gland and the fatty tissues throughout the body, but this amount is very small compared with premenopausal levels. Estrogen has widespread effects on both genital and extragenital systems, and the withdrawal of estrogen accounts for many of the signs and symptoms attributed to menopause, although these are influenced by both hereditary and social factors. Many psychological problems have been attributed to estrogen deprivation, but well-documented proof of those relationships is lacking.

While estrogen can reverse or halt many of the physical changes described, it will not prevent aging or restore reproductive ability. Treatment of menopausal symptoms should be undertaken on an individual basis, with careful discussion of the risks and benefits currently known. See also Estrogen; Menstruation.


 

Definition

Menopause represents the end of menstruation. While technically it refers to the final menstrual period, it is not an abrupt event, but a gradual process. Menopause is not a disease that needs to be cured, but a natural life-stage transition. However, women have to make important decisions about managing its symptoms, including the use of hormone replacement therapy (HRT).

Description

Many women have irregular periods and other problems of perimenopause for years. It is not easy to predict when menopause begins, although doctors agree it is complete when a woman has not had a period for a full year. Eight out of every 100 women stop menstruating before age 40. At the other end of the spectrum, five out of every 100 continue to have periods until they are almost 60. The average age of menopause is 51.

There is no method to determine when the ovaries will begin to scale back but a woman can get a general idea based on her family history, body type, and lifestyle. Women who began menstruating early will not necessarily stop having periods early. A woman will likely enter menopause at about the same age as her mother.

Causes & Symptoms

Once a woman enters puberty, each month her body releases one of the more than 400,000 eggs that are stored in her ovaries, and the lining of the womb (uterus) thickens in anticipation of receiving a fertilized egg. If the egg is not fertilized, progesterone levels drop and the uterine lining sheds and bleeds.

By the time a woman reaches her late 30s or 40s, her ovaries begin to produce less estrogen and progesterone and release eggs less often. The gradual decline of estrogen causes a wide variety of changes in tissues that respond to estrogen—including the vagina, vulva, uterus, bladder, urethra, breasts, bones, heart, blood vessels, brain, skin, hair, and mucous membranes. Over the long term, the lack of estrogen can make a woman more vulnerable to osteoporosis (which can begin in the 40s) and heart disease.

As the levels of hormones fluctuate, the menstrual cycle begins to change. Some women may have longer periods with heavy flow followed by shorter cycles and very little bleeding. Others will begin to miss periods completely. During this time, a woman also becomes less able to get pregnant.

The most common symptom of menopause is a change in the menstrual cycle, but there are various other symptoms as well, including:

  • hot flashes
  • night sweats
  • insomnia
  • mood swings/irritability
  • memory or concentration problems
  • vaginal dryness
  • heavy bleeding
  • fatigue
  • depression
  • hair changes
  • hadaches
  • heart palpitations
  • sexual disinterest
  • urinary changes
  • weight gain

Diagnosis

The clearest indication of menopause is the absence of a period for one full year. It is also possible to diagnose menopause by testing hormone levels. If it has been at least three months since a woman's last period, a follicle-stimulating hormone (FSH) test might be helpful in determining whether menopause has occurred. FSH levels rise steadily as a woman ages. The FSH test alone cannot be used as proof that a woman has entered early menopause. A better measure of menopause is to determine the levels of FSH, estrogen, progesterone, testosterone, and other hormones.

Treatment

Some women also report success in using natural remedies to treat the unpleasant symptoms of menopause. Not all women need estrogen and some women cannot take it due to adverse side effects. Many doctors do not want to give hormones to women who are still having their periods, however erratically. Only a third of menopausal women in the United States try HRT and of those who do, eventually half of them drop the therapy. As for alternative therapies, most have only received attention in the United States in the past decade or so. Debate continues until scientific studies can prove these treatments' effectiveness on menopausal symptoms. As interest in alternative therapies for menopause continues, so will research. In the meantime, women should consult their physicians when adding alternative therapies to treatment of menopause symptoms.

General dietary recommendations include raw foods, fruits, fresh vegetables, whole grains, nuts, seeds, and fresh vegetable juices. Some foods are recommended because they contain phytoestrogens. Intake of dairy products and meats should be reduced. Pork and lunch meats should be avoided.

Herbs

Herbs have been used to relieve menopausal symptoms for centuries. Women who choose to take herbs for menopausal symptoms should learn as much as possible about herbs and work with a qualified practitioner (an herbalist, a traditional Chinese doctor, or a naturopathic physician).

The following list of herbs include those that herbalists recommend to treat menopausal symptoms:

  • black cohosh (Cimicifuga racemosa): shown to reduce hot flashes, other menstrual complaints at a recommended dose of 20 mg twice daily
  • black currant: breast tenderness
  • chaste tree/chasteberry (Vitex agnus-castus): hot flashes, excessive menstrual bleeding, moodiness
  • chickweed (Stellaria media): hot flashes
  • evening primrose oil (Oenothera biennis): mood swings, irritability, breast tenderness
  • fennel (Foeniculum vulgare): hot flashes, digestive gas, bloating
  • flaxseed (linseed): excessive menstrual bleeding, breast tenderness, and other symptoms, including dry skin and vaginal dryness
  • ginkgo (Ginkgo biloba): memory problems
  • ginseng (Panax ginseng): hot flashes, fatigue, vaginal thinning
  • hawthorn (Crataegus laevigata): memory problems, fuzzy thinking
  • horsetail (Equisetum arvense): osteoporosis
  • lady's mantle: excessive menstrual bleeding
  • Licorice (Glycyrrhiza glabra) root: general menopausal symptoms
  • Mexican wild yam (Dioscorea villosa) root: vaginal dryness, hot flashes, general menopause symptoms
  • motherwort (Leonurus cardiaca): night sweats, hot flashes
  • oat (Avena sativa) straw: mood swings, anxiety
  • passionflower (Passiflora incarnata): insomnia, pain
  • raspberry leaf: normalizes hormonal system
  • sage (Salvia officinalis): mood swings, headaches, night sweats
  • skullcap (Scutellaria lateriflora): insomnia
  • sesame oil: vaginal dryness (applied topically)
  • valerian (Valeriana officinalis): insomnia
  • violet (Viola odorata): hot flashes.

Phytoestrogens

Proponents of plant estrogens (including soy products) believe that phytoestrogens are better than synthetic estrogen, but this has not been proven. The results of small preliminary trials suggest that the estrogen compounds in soy products can relieve the severity of hot flashes and lower cholesterol. It has not been proven that soy can provide all the benefits of synthetic estrogen without its negative effects.

Women in other countries who eat foods high in plant estrogens (especially soy products) have lower rates of breast cancer and report fewer symptoms of menopause. While up to 80% of menopausal women in the United States complain of hot flashes, night sweats, and vaginal dryness, only 15% of Japanese women have similar complaints. When all other things are equal, a soy-based diet may make a difference (and soy is very high in plant estrogens). One study showed positive effects from soy, but they only lasted about six weeks.

Several studies have shown that a black cohosh extract (Remifemin) relieved menopausal symptoms as well as or better than estrogen and that it showed the greatest promise among alternative treatments. Side effects were rare. Flaxseeds also are a good source of phytoestrogens. Other sources include red clover leaf, licorice, wild yam, chick peas, pinto beans, french beans, lima beans, and pomegranates. In 2003, red clover leaf was thought to offer relief for hot flashes, but in two short clinical trials, it failed to demonstrate hot flash relief.

Herbal practitioners recommend a dose based on a woman's history, body size, lifestyle, diet, and reported symptoms. In one study at Bowman-Gray Medical School in North Carolina, women were able to ease their symptoms by eating a large amount of fruits, vegetables, and whole grains, together with 4 oz of tofu four times a week.

Many women think that natural or plant-based means harmless. In large doses, phytoestrogens can promote the abnormal growth of cells in the uterine lining. Unopposed estrogen of any type can lead to endometrial cancer. However, a plant-based progesterone product sometimes can be effective alone, without estrogen, in assisting the menopausal woman in rebalancing her hormonal action throughout this transition time.

Homeopathy

Homeopathic remedies for menopausal symptoms have been clinically successful. For best results, the patient should consult a homeopathic physician. However, the following remedies can be tried to alleviate specific groups of symptoms:

  • lachesis: hot flashes, irritability, talkativeness, tightness around abdomen, dizziness, fainting
  • sepia: bleeding between periods, chilliness, tearfulness, withdrawal from loved ones, sinking feeling in stomach
  • pulsatilla: tearfulness, thirstless, feels better with others, avoids heat, hot flashes, varicose veins, hemorrhoids
  • sulfur: philosophical personality, feeling hot, itching and burning of vagina and rectum
  • lycopodium: low self esteem, bloated after eating, infrequent menstruation, low blood sugar, weak digestion, belching
  • Argentum nitricum: gas, indigestion, craving for sweets and chocolate, panic attacks, fear of crossing bridges
  • Magnesium phosphoricum: severe cramping
  • transitional formula: hot flashes, night sweats, insomnia, skin-crawling sensation
  • women's formula: perimenopause, PMS, irregular cycles, infertility, absent or excessive bleeding, menopausal discomfort
  • vital formula: anxiety, headaches, palpitations, PMS, mood swings

Yoga

Many women find that yoga can ease menopausal symptoms. Yoga focuses on helping women unite the mind, body, and spirit to create balance. Because yoga has been shown to balance the endocrine system, some experts believe it may affect hormone-related problems. Studies have found that yoga can reduce stress, improve mood, boost a sluggish metabolism, and slow the heart rate. Specific yoga positions deal with particular problems, such as hot flashes, mood swings, vaginal and urinary problems, and other pains.

Exercise

Exercise helps ease hot flashes by lowering the amount of circulating FSH and LH and by raising endorphin levels (which drop during a hot flash). Even exercising 20 minutes three times a week can significantly reduce hot flashes. Weight bearing exercises help to prevent osteoporosis.

Elimination

Regular, daily bowel movements to eliminate waste products from the body can be crucial in maintaining balance through menopause. The bowels are where circulating hormones are gathered and eliminated, keeping the body from recycling them and causing an imbalance.

Acupuncture

This ancient Asian art involves placing very thin needles into different meridian points on the body to stimulate the system and unblock energy. It usually is painless and has been used for many menopausal symptoms, including insomnia, hot flashes, and irregular periods.

Acupressure and Massage

Therapeutic massage involving acupressure can bring relief from a wide range of menopause symptoms by placing finger pressure at the same meridian points on the body that are used in acupuncture. There are more than 80 different types of massage, including foot reflexology, Shiatsu massage, and Swedish massage, but they all are based on the idea that boosting the circulation of blood and lymph benefits health. Breast massage (rubbing castor oil or olive oil on the breasts for five minutes thrice weekly) balances hormone levels, helps the uterus contract during menstruation, and prevents cramping pains.

Biofeedback

Some women have been able to control hot flashes through biofeedback, a painless technique that helps a person train her mind to control her body. A biofeedback machine provides information about body processes (such as heart rate) as the woman relaxes her body. Using this technique, it is possible to control the body's temperature, heart rate, and breathing.

Other Treatments

Therapeutic touch, an energy-based practice, may relieve menopausal symptoms. Cold compresses on the face and neck can ease hot flashes. Sound or music therapy may relieve stress and other menopausal symptoms. Prayer or meditation can help improve coping ability.

Supplementation with magnesium, calcium, vitamin D, vitamin K, boron, manganese, and phosphorous is used to prevent osteoporosis. Vitamin E supplementation may reduce hot flashes and risk of heart disease.

Allopathic Treatment

When a woman enters menopause, her levels of estrogen drop and troublesome symptoms begin. Hormone replacement therapy (HRT) can suppress symptoms by boosting the estrogen levels while also providing protection against heart disease and osteoporosis (bone weakening). There are two types of hormone treatments: hormone replacement therapy (HRT) and estrogen replacement therapy (ERT). HRT is the administration of estrogen and progesterone; ERT is the administration of estrogen alone. Only women who have had a hysterectomy (removal of the uterus) can take estrogen alone, since taking this "unopposed" estrogen can cause uterine cancer. The combination of progesterone and estrogen in HRT eliminates the risk of uterine cancer.

Experts once disagreed on whether HRT increases or decreases the risk of developing breast cancer. A Harvard study concluded that short-term use of hormones carried little risk, while HRT used for more than five years among women 55 and over seemed to increase the risk of breast cancer. In 2002, the Women's Health Initiative (WHI) quieted much of the disagreement, particularly concerning long-term use of HRT. Use of combined estrogen and progestin therapy was stopped in the large trial when invasive breast cancer risk hit a threshold among participants. The risks of HRT were determined to outweigh the benefits. Use of combined HRT also increased risk of coronary heart disease, stroke and even dementia.

Following the WHI, many physicians have cautioned women to discuss the benefits and risks of HRT with their doctors on an individual basis. In some cases, the benefits of short-term use of HRT still may outweigh the risks.

Women remain poor candidates for hormone replacement therapy if they:

  • have ever had breast or endometrial cancer
  • already have heart disease
  • have a close relative (mother, sister, grandmother) who died of breast cancer or have two relatives who got breast cancer before age 40
  • have had endometrial cancer
  • have had gallbladder or liver disease
  • have blood clots or phlebitis

Women would make a good candidate for HRT if they:

  • need to prevent osteoporosis
  • have had their ovaries removed
  • have significant symptoms
  • need short-term symptom relief

Aside from the findings of the WHI concerning risks of HRT, side effects of treatment include bloating, breakthrough bleeding, headaches, vaginal discharge, fluid retention, swollen breasts, or nausea. A 2001 study reported that HRT might worsen asthma in post-menopausal women who had asthma prior to menopause. Some side effects can be lessened or prevented by changing the HRT regimen.

The decision should be made by a woman and her doctor after taking into consideration her medical history and situation. Women who choose to take hormones should have an annual mammogram, breast exam, and pelvic exam and should report any unusual vaginal bleeding or spotting (a sign of possible uterine cancer).

Anti-Estrogens

This new type of hormone therapy offers some of the same protection against heart disease and bone loss as estrogen, but without the increased risk of breast cancer.

The best known of these anti-estrogens is raloxifene (Evista), which mimics the effects of estrogen in the bones and blood, but blocks some of its negative effects elsewhere. It is called an anti-estrogen because for a long time these drugs had been used to counter the harmful effects of estrogen that caused breast cancer. Oddly enough, in other parts of the body these drugs mimic estrogen, protecting against heart disease and osteoporosis without putting a woman at risk for breast cancer.

Testosterone Replacement

The ovaries also produce a small amount of male hormones (about 300 micrograms), which decrease slightly as a woman enters menopause. Most women never need testosterone replacement. Testosterone can improve the libido, and decrease anxiety and depression; adding testosterone is especially beneficial to women who have had hysterectomies. Testosterone also eases breast tenderness and helps prevent bone loss. Side effects include mild acne and some facial hair growth.

Birth Control Pills

Women who are still having periods but who have annoying menopausal symptoms may take low-dose birth control pills to ease the problems; this treatment has been approved by the FDA for perimenopausal symptoms in women under age 55. HRT uses lower doses of estrogen, however.

Expected Results

Menopause is a natural condition of aging. Some women have no problems with menopause, while others notice significant unpleasant symptoms. Results of allopathic and alternative treatments vary from one woman to another.

Prevention

Menopause can't be prevented, though some of the symptoms can be relieved by the treatments listed above.

[Article by: Belinda Rowland; Teresa G. Odle]

 

Final cessation of menstruation, ending female fertility. It usually begins between ages 45 and 55. A gradual decline in function of the ovaries reduces estrogen production. Ovulation becomes irregular and gradually ceases. The length of the menstrual cycle and periods may vary; flow may lessen or increase. Adjustment of the endocrine system to estrogen reduction causes hot flashes, often at night, with a warm sensation, flushing, and sweating; other symptoms, such as irritability and headaches, may be related more to reactions to aging. Removal or destruction of the ovaries to treat disease causes artificial menopause, with similar but more sudden effects. Changes in hormone balance usually cause no physical or mental disturbances. However, the protective effect of estrogen against osteoporosis and atherosclerosis is lost, and risks of fracture and coronary heart disease increase.

Columbia Encyclopedia: menopause

menopause (mĕn'əpôz) or climacteric (klīmăk'tərĭk, klī'măktĕr'ĭk) , transitional phase in a woman's life when the ovaries stop releasing eggs, ovarian production of estrogen and other hormones tapers off, and menstruation ceases. It results from declining ovarian function due to aging of the ovaries and is usually a gradual process. In the United States, natural menopause occurs at age 51 on average. Premature menopause (due to premature aging of the ovaries, debilitating disease, or infection) and artificial menopause (due to destruction of the ovaries by surgery, irradiation, or purposeful hormone therapy, as in severe premenstrual syndrome) may occur much earlier.

Menopause may pass with no signs other than cessation of menstruation, or it may be accompanied by menstrual changes (heavy or erratic periods), night sweats, hot flashes, and vaginal dryness. There is some debate as to whether emotional symptoms and “mood swings” are any more common during menopause than at any other age. Lower levels of estrogen following menopause may be accompanied by a variety of physical changes. For example, the risk of osteoporosis, in which the bones lose elasticity and become brittle, increases. In addition, levels of high-density lipoproteins (HDLs) decrease as low-density lipoproteins (LDLs) increase, arteries lose elasticity, and more body weight is redistributed to the waist area—all heightening the risk of heart disease. Other possible estrogen-related changes include stress incontinence due to loss of muscle tone in the pelvis, loss of elasticity in the skin, and hair thinning.

Estrogen replacement therapy (ERT) is a controversial treatment introduced in the 1970s for bodily changes that occur in menopause; beginning in the 1980s progestins were added to reduce the risk of uterine cancer. Although ERT eases hot flashes and other physical changes and appears to decrease the risk of osteoporosis, it has been linked to increases in breast cancer, heart disease, and stroke.

Other approaches to dealing with the physical changes include exercise to help circulation, increase bone density and HDL levels, and lower stress; lubricants for vaginal dryness; avoidance of smoking and excess alcohol; and dietary changes limiting protein and fat and increasing fiber and calcium. Natural remedies such as vitamins E and B6 or ginseng and other foods that contain or mimic estrogen are sometimes recommended, but research as to their efficacy has been limited.

Menopause is the permanent cessation of reproductive fertility some time before the end of the natural lifespan. The term was originally used to describe this reproductive change in human females, where the end of fertility was traditionally indicated by the permanent stopping of menstruation or "menses". The word "menopause" literally means the "end of monthly cycles" from the Greek words pausis (cessation) and the word root men (month).

The meaning of the word menopause has in more recent times been expanded to indicate the permanent discontinuation of female fertility in many other species, such as some matrilineal whales, despite the fact that such animals experience no menstrual cycles.

Contents

Menopause in humans

In adult human females who still have a uterus, and who are not pregnant or lactating, postmenopause is identified by a permanent (at least one year's) absence of monthly periods or menstruation. In women without a uterus, menopause or postmenopause is identified by a very high FSH level.

In human females, menopause usually happens more or less in midlife, signaling the end of the fertile phase of a woman's life. Menopause is perhaps most easily understood as the opposite process to menarche, the start of the monthly periods. However, menopause in women cannot satisfactorily be defined simply as the permanent "stopping of the monthly periods", because in reality what is happening to the uterus is quite secondary to the process; it is what is happening to the ovaries that is the crucial factor.

As an illustration of this point: for medical reasons, the uterus must sometimes be surgically removed (hysterectomy) in a younger woman; her periods will cease permanently, and the woman will technically be infertile, but as long as at least one of her ovaries is still functioning, the woman will not have reached menopause. Even without the presence of the uterus, ovulation and the release of the sequence of reproductive hormones will continue to cycle on, until menopause is reached. But in circumstances where a woman's ovaries are removed (oophorectomy), even if the uterus were to be left intact, the woman will immediately be in "surgical menopause".

Thus menopause is based on the natural or surgical cessation of hormone production by the ovaries, which are a part of the body's endocrine system of hormone production, in this case the hormones which make reproduction possible and can influence sexual behavior. The resultant decreased levels of circulating estrogen impacts the entire cascade of a woman's reproductive functioning, from brain to skin.

The menopause transition, and post-menopause itself, is a natural life change, not a disease state or a disorder. The transition itself can be challenging for a number of women, but for others it is not difficult.

Age of onset

In the Western world, the most typical age range for the occurrence of menopause is between the ages of 45 and 55[1] and the average age for last period ever is 51 years[2]. In some developing countries however, such as India and the Philippines, the median age of natural menopause is considerably earlier, at 44 years[3].

In the Western World, a woman's last period ever occurring between the ages of 55 to 60 is known as a "late menopause". An "early menopause" is defined as having the final period somewhere between the age of 40 to 45.

Rarely a woman's ovaries stop working at a very early age, anywhere from the age of puberty to age 40, and this is known as premature ovarian failure (POF). POF is not considered to be due to the normal effects of aging. Some known causes of premature ovarian failure include autoimmune disorders, thyroid disease, diabetes mellitus, chemotherapy, and radiotherapy. However, in the majority of spontaneous cases of premature ovarian failure, the cause is unknown.

Premature ovarian failure is diagnosed or confirmed by measuring the levels of follicle stimulating hormone (FSH) and luteinizing hormone (LH); the levels of these hormones will be abnormally high if menopause has occurred. Rates of premature menopause have been found to be significantly higher in fraternal and identical twins; approximately 5% of twins reach menopause before the age of 40. The reasons for this are not completely understood. Transplants of ovarian tissue between identical twins have been successful in restoring fertility.

On average, women who smoke cigarettes experience menopause significantly earlier than non-smokers.[4]

Menopause in other species

Menopause in the animal kingdom appears perhaps to be somewhat uncommon, although the incidence in different species has not been thoroughly researched. However, it is already quite apparent that humans are not the only species that experience it. Menopause has been observed in rhesus monkeys[5] and all other primates, elephants [2], some cetaceans[6], as well as in a variety of other vertebrate species including the guppy[7], the platyfish, the budgerigar, the laboratory rat and mouse, and the opossum.

Menopause in human evolution

The Grandmother hypothesis suggests that menopause evolved in humans because it promotes the survival of grandchildren. According to this hypothesis, post reproductive women feed and care for children, adult nursing daughters, and grandchildren whose mothers have weaned them. Human babies require large and steady supplies of glucose to feed the growing brain. In infants in the first year of life, the brain consumes 60% of all calories, so both babies and their mothers require a dependable food supply. Some evidence suggests that hunters contribute less than half the total food budget of most hunter-gatherer societies, and often much less than half, so that foraging grandmothers can contribute substantially to the survival of grandchildren at times when mothers and fathers are unable to gather enough food for all of their children. In general, selection operates most powerfully during times of famine or other privation. So although grandmothers might not be necessary during good times, many grandchildren cannot survive without them during times of famine. Arguably, however, there is not a firm consensus on the evolutionary advantages of menopause. However, considering the demands of childbirth upon the mother, a view of the human body as an engineering system design would reasonably include the cessation of reproductive capability in time to prevent unnecessary risk to the health of either mother or child due to age of the mother during childbirth and nursing.

Social and psychological significance: the three ages

The end of fertility in midlife ushers in the third part of a woman's life, also known as the "third age". Generally, women raised or living in Western countries live long enough so that half of their adult life is spent in post-menopause. For some women, the menopausal transition represents a major life change, similar to menarche in the magnitude of its social and psychological significance.

In the ancient past, menarche and menopause were considered to mark the transitions from "maiden" to "matron", and from "matron" to "crone", (in other words, from little girl to reproductive woman and then to older woman.) Although the significance of the changes that surround menarche is still fairly well recognized, in countries such as the USA, the social and psychological ramifications of the menopause transition are frequently ignored or underestimated.

Terminology, definitions and commentary

Menopause

Clinically speaking, menopause is a date. For those women who still have a uterus, menopause is defined as the day after a woman's final period finishes. This date is fixed retrospectively, once 12 months have gone by with no menstrual flow at all. At this point a woman is considered to be a year into postmenopause, is considered to be infertile, and no longer needs to take into consideration the possibility of pregnancy.

In common everyday parlance however, the word "menopause" is usually not used to refer to one day, but to the whole of the menopause transition years. This span of time is also referred to as the change of life, the change, or the climacteric and more recently is known as "perimenopause", (literally meaning "around menopause").

The word menopause is also often used in popular parlance to mean all the years of postmenopause.

Perimenopause

In biomedicine, perimenopause is the term describing the menopause transition years. In women who have a uterus, perimenopause describes the years both before and after the final period (although it is only possible to determine in retrospect which episode of flow was indeed the final period).

During perimenopause, the production of most of the reproductive hormones, including the estrogens, progesterone and testosterone, diminish and become more irregular, often with wide and unpredictable fluctuations in levels. During this period, fertility diminishes, but is not considered to reach zero until the official date of menopause. This is however determined retroactively, 12 months after the last appearance of menstrual blood. Signs and effects of the menopause transition can begin as early as age 35, although most women who become aware of the transition do so about 10 years later, often in their mid to late 40s. The duration of perimenopause with noticeable bodily effects can be a few years, ten years or even longer. The actual duration and severity of perimenopause in any individual woman cannot currently be predicted in advance, or during the process.

In the perimenopause years, many women undergo bodily changes resulting from hormonal fluctuation. The most well-known effect of menopause is the "hot flash" or "hot flush", a sudden increase in body temperature; the "flash" sensation in a "hot flash" occurs as the body temperature peaks and begins a rapid return to normal. Hot flashes can become so strong that they can raise the body temperature multiple degrees in a very short period of time and cause the sufferer to feel weak and break out in heavy sweating. Despite the discomfort to the woman, hot flashes are not considered harmful by physicians. Although flashes are not harmful, they can be treated in an attempt to ease discomfort, using prescription medications such as hormone treatment, or SSRI medications, or by using over-the-counter plant estrogens and herbal remedies.

Other common effects encountered during the perimenopausal period include mood changes, insomnia, fatigue, and memory problems. Some of these complaints may not be related to the actual hormonal fluctuations involved in menopause, but if this is indeed the case, not enough research has been done to determine why some women in menopause report these effects.

Even women who are free of any troublesome physical effects of perimenopause may nonetheless find themselves suffering from psychological issues related to societal perceptions of aging; these issues also lend themselves to medical treatment to lessen their overall impact on a woman's life.

One piece of recent research shows that melatonin supplementation in perimenopausal women can produce a significant improvement in thyroid function and gonadotropin levels, as well as restoring fertility and menstruation and preventing the depression associated with the menopause.[8]

Premenopause

Premenopause is a word used to describe the years leading up to the last period ever, when the levels of reproductive hormones are already becoming lower and more erratic, and the effects of hormone withdrawal may be present.

Postmenopause

Postmenopause is all of the time in a woman's life that take place after her last period ever, or more accurately, all of the time that follows the point when her ovaries become inactive.

A woman who still has her uterus (and who is neither pregnant nor lactating) can be declared to be in postmenopause once she has gone 12 full months with no flow at all, not even any spotting. When she reaches that point, she is one year into postmenopause.

The reason for this delay in declaring a woman postmenopausal is because periods are usually extremely erratic at this time of life, and therefore a reasonably long stretch of time is necessary to be sure that the cycling has actually ceased completely.

At this point a woman is considered infertile, and no longer needs to factor in the possibility of becoming pregnant. However the possibility of becoming pregnant has usually been very low (but not zero) for a number of years before this point is reached.

In women who have no uterus, and therefore have no periods, post-menopause can be determined by a blood test which can reveal the very high levels of Follicle Stimulating Hormone (FSH) that are typical of post-menopausal women.

A woman's reproductive hormone levels continue to drop and fluctuate for some time into post-menopause, so any hormone withdrawal symptoms that a woman may be experiencing do not necessarily stop right away, but may take quite some time, even several years, to disappear completely.

Any period-like flow that might occur during postmenopause, even just spotting, must be reported to a doctor. The cause may in fact be minor, but the possibility of endometrial cancer must be checked for and eliminated.

The causes of menopause

The causes of menopause can be considered from complementary proximate (mechanistic) and ultimate (adaptive evolutionary) perspectives.

Ultimate perspective

One possible ultimate perspective on menopause is outlined above in the "Menopause in human evolution" section.

Proximate perspective

A natural or physiological menopause is that which occurs as a part of a woman's normal aging process. It is the result of the eventual atresia of almost all oocytes in the ovaries. This causes an increase in circulating follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels as there are a decreased number of oocytes responding to these hormones and producing estrogen. This decrease in the production of estrogen leads to the perimenopausal symptoms of hot flashes, insomnia and mood changes, as well as post-menopausal osteoporosis and vaginal atrophy.

However, menopause can be surgically induced by bilateral salpingo-oophorectomy (removal of both ovaries and both fallopian tubes), which is often, but not always, done in conjunction with hysterectomy. Cessation of menses as a result of removal of the ovaries is called "surgical menopause". The sudden and complete drop in reproductive hormone levels usually produces extreme hormone-withdrawal symptoms such as hot flashes, etc.

As mentioned above, removal of the uterus, hysterectomy, does not itself cause menopause, although pelvic surgery can often precipitate a somewhat earlier menopause, perhaps because of a compromised blood supply to the ovaries. Removing the ovaries however, causes an immediate and powerful "surgical menopause", even if the uterus is left intact.

Cigarette smoking has been found to decrease the age at menopause by as much as one year, and women who have undergone hysterectomy with ovary conservation go through menopause 3.7 years earlier than average. However, premature menopause (before the age of 40) is generally idiopathic.

Possible effects of perimenopause, the menopause transition time

During the menopause transition years, as the body responds to the rapidly changing levels of natural hormones, a number of effects may appear.

Not every woman experiences bothersome levels of these effects, and even in those women who do experience strong effects, the range of effects and the degree to which they appear is very variable from person to person.

Those effects that are due to low estrogen levels (for example vaginal atrophy and skin drying) remain present even after the menopause transition years are over; however, many of the effects that are caused by the extreme fluctuations in hormone levels (for example hot flashes and mood changes) usually disappear or improve significantly once the perimenopause transition time has been completed.

Both users and non-users of hormone replacement therapy identify lack of energy as the most frequent and distressing effect.[9] Other effects can include vasomotor symptoms such as hot flashes and palpitations, psychological effects such as depression, anxiety, irritability, mood swings, memory problems and lack of concentration, and atrophic effects such as vaginal dryness and urgency of urination.

The average woman also has increasingly erratic menstrual periods, due to skipped ovulations. Typically, the timing of the flow becomes unpredictable. In addition the duration of the flow may be considerably shorter or longer than normal, and the flow itself may be significantly heavier or lighter than was previously the case, including sometimes long episodes of spotting. Early in the process it is not uncommon to have some 2-week cycles. Further into the process it is common to skip periods for months at a time, and these skipped periods may be followed by a heavier period. The number of skipped periods in a row often increases as the time of last period approaches. At the point when a woman of menopausal age has had no periods or spotting for 12 months she is considered to be one year into post-menopause. However, a period after 6 months of no flow at all is sometimes considered worthy of investigation by a doctor.

All the various possible perimenopause effects are caused by an overall drop, as well as dramatic but erratic fluctuations, in the absolute levels and relative levels of estrogens and progesterone. Some of the effects, such as formication, may be associated directly with hormone withdrawal.

Vascular instability

Urogenital atrophy, also known as vaginal atrophy, (main article: Atrophic vaginitis)

Skeletal

Skin, soft tissue

  • breast atrophy
  • skin thinning and becoming drier
  • decreased elasticity of the skin
  • formication, a sensation rather like pins and needles, more specifically like ants crawling on or under the skin

Psychological

Sexual

Cohort studies have reached mixed conclusions about medical conditions associated with the menopause. For example, a 2007 study found that menopause was associated with hot flashes; joint pain and muscle pain; and depressed mood.[11] In the same study, it appeared that menopause was not associated with poor sleep, decreased libido, and vaginal dryness.[11] However, a 2008 study found an association with poor sleep quality.[12]

Influence of cultural context

The cultural context within which a woman lives can have a significant impact on the way she experiences the menopausal transition. Within the United States, social location affects the way women perceive menopause and its related biological effects. Research indicates that whether a woman views menopause as a medical issue or an expected life change is correlated with her socio-economic status [13]. The paradigm within which a woman considers menopause also influences the way she views it: women who understand menopause as a medical condition rate it significantly more negatively than those who view it as a life transition or a symbol of aging [14].

Ethnicity and geographical location also play a role in the experience of menopause. U.S. women of different ethnicities report significantly different types of menopausal "symptoms". One major study found Caucasian women most likely to report what are sometimes described as psychosomatic symptoms, while African-American women were more likely to report vasomotor symptoms [15]. Additionally, while most women in the United States have a negative view of menopause as a time of deterioration or decline, some studies indicate that Asian women have an understanding of menopause that focuses on a sense of liberation, and celebrates the freedom from the risk of pregnancy [16]. Diverging from these conclusions, one study appeared to show that many U.S. women "experience this time as one of liberation and self-actualization" [17].

Need for more education about menopause

Many women arrive at their menopause years without knowing anything about what they might expect, or when or how the process might happen, and how long it might take. Very often a woman has not been informed in any way about this stage of life; at least in the US, it may often be the case that she has received no information from her physician, or from her older female family members, or from her social group. In the US, there appears to be a lingering taboo which hangs over this subject.

As a result, a woman who happens to undergo a strong perimenopause with a large number of different effects, may become confused and anxious, fearing that something abnormal is happening to her. There is a strong need for more information and more education on this subject.[9]

Palliative therapies

Perimenopause is a natural stage of life. It is not a disease or a disorder, and therefore it does not automatically require any kind of medical treatment. However, in cases where the physical, mental, and emotional effects of perimenopause are severe, and disrupt the everyday life of the woman experiencing them, palliative medical therapy may sometimes be appropriate and helpful.

Hormone therapy, also known as hormone replacement therapy

See also Hormone replacement therapy (menopause).

There are several types of hormone therapies, with various possible side effects. Hormone replacement therapy or HRT, known in Britain as Hormone Therapy or HT, and the SSRIs appear to provide the most reliable pharmaceutical relief. However, adverse effects of one kind of HRT (equine estrogen combined with a synthetic progestin) are now well documented. See the section below on "Adverse effects of conjugated equine estrogens".

In addition to relief from hot flashes, hormone therapy remains an effective treatment for osteoporosis.

A woman and her doctor should carefully review her situation, her complaints and her relative risk before determining whether the benefits of HT/HRT or other therapies outweigh the risks. Until more becomes understood about the possible risks, women who elect to use hormone replacement therapy are generally well advised to take the lowest effective dose of hormones for the shortest period possible, and to question their doctors as to whether certain forms might pose fewer dangers of clots or cancer than others.

In HT or HRT, one or more estrogens, usually in combination with progesterone, (and sometimes testosterone) are administered, not only to partially compensate for the body's loss of these hormones, but also in an attempt to keep the levels of these hormones in the body much more consistent than they are naturally in perimenopause.

In those women who have no uterus (usually due to a previous hysterectomy) estrogen alone is a suitable hormone therapy. Women who still have a uterus need to take progesterone in addition to estrogen, in order to ensure that the endometrium, the lining of the uterus, does not build up too much, which would be a risk for cancer of the endometrium.

Conjugated equine estrogens

See also Types of Hormone Replacement Therapy

Conjugated equine estrogens contain estrogen molecules conjugated to hydrophilic side groups (e.g. sulfate) and are produced from the urine of pregnant Equidae (horses) mares. Premarin is the prime example of this, either alone or in Prempro, where it is combined with a synthetic progestin, medroxyprogesterone acetate. However Premarin, and especially Prempro, are associated with serious health risks.[18]

In January 2003, the U.S. Food and Drug Administration required Wyeth to affix a "black box" warning to PremPro, stating:

"WARNING: Estrogens and progestins should not be used for the prevention of cardiovascular disease. The Women’s Health Initiative (WHI) reported increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women during 5 years of treatment with conjugated equine estrogens (0.625 mg) combined with medroxyprogesterone acetate (2.5 mg) relative to placebo (see CLINICAL PHARMACOLOGY, Clinical Studies). Other doses of conjugated estrogens and medroxyprogesterone acetate, and other combinations of estrogens and progestins were not studied in the WHI ..."

Adverse effects of conjugated equine estrogens

See also Types of Hormone Replacement Therapy

Women had been advised for many years by numerous doctors and drug company marketing efforts (at least in the USA) that hormone therapy with conjugated equine estrogens after menopause might reduce their risk of heart disease and prevent various aspects of aging. However, a large, randomized, controlled trial (the Women's Health Initiative) found that women undergoing HT or HRT with conjugated equine estrogens (Premarin), whether or not used in combination with a synthetic progestin (Premarin plus Provera, known as Prempro), had an increased risk of breast cancer, heart disease, stroke, and Alzheimer's disease. Although this increase in risk was small overall, it passed the thresholds that had been established by the researchers in advance as sufficient to ethically require stopping the study.

When these results were first reported in 2002, the popular media sensationalized the story and exaggerated the risk, while the manufacturer continued to attempt to minimize the degree of risk. However most news stories failed to mention that the average age of the women in WHI was 62 years old, significantly older than the time when most doctors start patients on HRT, and in fact many years into postmenopause. In order to enroll in the study, patients had to be asymptomatic of hot flashes, so they would not know whether they received the placebo. For these reasons WHI was not representative of generally accepted clinical practice.

The 2002 and 2003 announcements of the Women's Health Initiative of the American National Institute of Health and The Million Women Study of the UK Cancer Research and National Health Service collaboration respectively, that HRT treatment coincides with a increased incidence of breast cancer, heart attacks and strokes, lead to a sharp decline in HRT prescription throughout the world [19][20][21], which was followed by a decrease in breast cancer incidence [22][23][24].

On hearing the news about the WHI study, many women discontinued equine estrogens altogether, with or without their doctor's approval. The number of prescriptions written for Premarin and PremPro in the United States dropped within a year almost to half of their previous level. This sharp drop in usage was followed by large and successively larger drops in new breast cancer diagnoses, at six months, one year, and 18 months after the drop in Premarin and Prempro prescriptions, for a cumulative 15% drop by the end of 2003. However, the apparent meaning of this correlation is called into question by the fact that prescriptions of Prempro and Premarin fell dramatically in Canada as well, but no similarly dramatic drop in Canada's breast cancer rates was observed during the same time period. Studies designed to track the further progression of this trend after 2003 are under way, as well as studies designed to quantify how much of the drop was related to the reduced use of HT/HRT.

Other forms of hormone therapy

See also Types of Hormone Replacement Therapy

The adverse biological effects of xenoestrogens and progestins revealed by studies of Premarin and PremPro do not necessarily generalize to supplementation with human forms of estrogen and progesterone. For example, a pilot study reported in JAMA by Smith, Heckbert, et al.[25] found clinical evidence that oral conjugated equine estrogens caused clotting, but the other estrogen compound tested in the same study, bioidentical esterified estrogens, did not. conjugated equine estrogens were found to be associated with increased venous thrombotic risk. In sharp contrast, the study found that users of esterified estrogen had no increase in venous thrombotic risk.

Due to the controversy about Premarin-based hormone therapy, a number of doctors are now moving patients who request hormone therapy to help them through perimenopause, to bioidentical hormone products.

Estrace is a form of the precursor to estrogen in the human body known as estradiol, which products have produced fewer side effects than conjugated equine estrogens[26]. Prometrium is a bioidentical progesterone which can be used in conjunction with Estrace.

However, all hormone replacement therapies probably do carry some health risks, including high blood pressure, blood clots, and increased risks of breast and uterine cancers. Women who have had a hysterectomy seem to tolerate estrogen-only therapy with fewer risks than apply to mixed-hormone therapy in women who still have a uterus.

The anti-seizure medication gabapentin (Neurontin) seems to be second only to HRT in relieving hot flashes.[27]

Selective Estrogen Receptor Modulators (SERMs)

SERMs are a category of drugs, either synthetically produced or derived from a botanical source (Phytoserms), that act selectively as agonists or antagonists on the estrogen receptors throughout the body. While most SERMs are known to increase hot flushes, Femarelle (DT56a) decreases them.[28][29] In addition to the relieving effects on menopausal symptoms, Femarelle also increases bone mass density (BMD),[30] making it protective against osteoporotic fractures. These effects are achieved by an agonistic interaction with estrogen receptors in the brain and bone. On the other hand, an antagonist interaction with estrogen receptors in the breast[31] and uterus,[32][33] has no effect on these tissues.

Antidepressants

Antidepressants such as paroxetine (Paxil), Fluoxetine hydrochloride (Prozac), and Venlafaxine hydrochloride (Effexor) have been used with some success in the treatment of hot flashes, improving sleep, mood, and quality of life. There is a theoretical reason why SSRI antidepressants might help with memory problems—they increase circulating levels of the neurotransmitter serotonin in the brain and restore hippocampal function. Prozac has been repackaged as Sarafem and is approved and prescribed for premenstrual dysphoric disorder (PMDD), a mood disorder often exacerbated during perimenopause and early menopause. PMDD has been found by PET scans to be accompanied by a sharp drop in serotonin in the brain, and to respond quickly and powerfully to SSRIs.

Gabapentin

This is a seizure medication that has also been used off-label for a variety of other conditions. It appears to be as effective as estrogen at reducing hot flashes. [3]

Blood pressure medicines

Blood pressure medicines including clonidine (Catapres) are about as effective as antidepressants for hot flashes, but do not have the other mind and mood benefits of antidepressants. However they may merit special consideration by women suffering both from high blood pressure and hot flashes.

Complementary and alternative therapies

It is important to examine the claim that there is little evidence that herbal remedies help relieve menopausal symptoms.[34] Some botanical sources, referred to as phytoestrogens, are known to have an estrogenic effect on the body and therefore create a moderated estrogenic effect. Others, such as Femarelle, were found to have Selective Estrogen Receptor Modulator (SERM) qualities [35], thereby reducing the safety risks involved in estrogenic-like treatments.

In the area of complementary and alternative therapies, acupuncture treatment is promising. There are some studies indicating positive effects, especially on hot flashes [36] [37] [38] but also others [39] showing no positive effects of acupuncture regarding menopause.

There are claims that soy isoflavones are beneficial concerning menopause. However, one study [40] indicated that soy isoflavones did not improve or appreciably affect cognitive functioning in postmenopausal women.

Other remedies which in some studies appear to work well, but in other studies appear to be no better than a placebo include red clover isoflavone extracts and black cohosh. Black cohosh can cause the stimulation of pre-existing breast cancer and liver toxicity.[34]

Other therapies

  • Lack of lubrication is a common problem during and after perimenopause. Vaginal moisturizers can help women with overall dryness, and lubricants can help with lubrication difficulties that may be present during intercourse. It is worth pointing out that moisturizers and lubricants are different products for different issues: some women feel unpleasantly dry all of the time apart from during sex, and they may do better with moisturizers all of the time. Those who need only lubricants are fine just using the lubrication products during intercourse.
  • Low-dose prescription vaginal estrogen products such as estrogen creams are generally a safe way to use estrogen topically, in order to help vaginal thinning and dryness problems (see vaginal atrophy) while only minimally increasing the levels of estrogen in the bloodstream.
  • In terms of managing hot flashes, lifestyle measures, such as drinking cold liquids, staying in cool rooms, using fans, removing excess clothing layers when a hot flash strikes, and avoiding hot flash triggers such as hot drinks, spicy foods, etc, may partially supplement (or even obviate) the use of medications for some women.
  • Individual counseling or support groups can sometimes be helpful to handle sad, depressed, anxious or confused feelings women may be having as they pass through what can be for some a very challenging transition time.
