Menopause -- the end of menstruation and fertility -- is a natural biological event, not a disease or illness. However, for some women physical and emotional symptoms can be difficult. Menopause involves hormonal changes in your body that may cause physical symptoms: As the ovaries stop producing female sex hormones (estrogen and progesterone), estrogen levels decline over a period of years. That decline can cause hot flashes, night sweats, and mood swings. For some women, menopause may bring on feelings of sadness. However, it's important to remember that menopause doesn't mean an end to your sexuality or that you are any less feminine. In fact, some women find the years after menopause to be a time of freedom, when they no longer have to think about having a period or becoming pregnant. Today, an estimated 50 million women in the United States have reached menopause. Most women will spend at least one-third of their lives in or beyond menopause.
Technically, menopause is considered complete when a woman has not had a period for an entire year. On average, menopause occurs at age 51, but it varies from person to person. Because menopause is a process that happens over several years, it is divided into two phases. Perimenopause, when you begin experiencing symptoms but are still having periods, can last 4 - 5 years. Postmenopause occurs once you have gone 12 months without a period. Your ovaries have stopped releasing eggs and produce much less estrogen.
Another type of menopause, known as surgical menopause, occurs if both ovaries are removed for medical reasons. This may be done at the time of a hysterectomy (removal of the uterus).
Postmenopausal women lose the protective effects of estrogen and are at increased risk for osteoporosis and heart disease. There are a variety of treatments available, however, to help ease the symptoms and reduce health risks associated with menopause.
Symptoms of menopause vary from woman to woman. Some studies even suggest that the signs and symptoms of menopause may vary between cultural groups. For example, up to 80% of American women experience hot flashes while only 10% of Japanese women experience that symptom. Some researchers speculate that may be due to differences in diet, lifestyle, or cultural attitudes toward aging.
The following are general symptoms of menopause:
Post menopausal women are at increased risk for:
Menopause is caused by a gradual reduction in the amount of estrogen and progesterone produced in the ovaries. Both hormones regulate your periods and enable you to become pregnant. In the years leading up to menopause, the ovaries start to produce lower amounts of estrogen and progesterone. The timing of menopause can vary greatly from woman to woman. Studies indicate that women who smoke may reach menopause at a younger age than those who do not smoke. Some researchers think the timing of menopause may be hereditary, but so far there isn't much scientific evidence to back up that theory.
Although menopause usually occurs naturally, it can happen through surgical removal of the ovaries (surgical menopause). Menopause can also be caused by ovarian failure from cancer therapy, such as chemotherapy or radiation treatments.
Menopause is part of the natural aging process for all women, unless it is caused by surgical removal of both ovaries (a bilateral oophorectomy). Surgical menopause tends to cause symptoms to come on more quickly. The following risk factors may also make menopausal symptoms occur faster:
Most women will recognize the signs that they are going through menopause. However, if you start to skip periods suddenly you should see your doctor for a pregnancy test -- it is possible to become pregnant when going through perimenopause (as long as you are having periods, even if they're irregular, you can become pregnant). In some cases, your doctor may order blood tests to check hormone levels. Your doctor may also suggest a bone density measurement. If you have moderate or severe symptoms that interfere with your life, talk to your doctor about what treatments might be right for you.
Although you can't prevent menopause, you can take action to reduce your risk of complications (such as osteoporosis and cardiovascular disease):
Menopause itself doesn't require treatment, but you may want to treat some symptoms and reduce your risk of long term medical conditions, such as heart disease and osteoporosis, that are more common after menopause. Many treatment options are available, so it is important to discuss them with your doctor.
In the past, a number of women took hormone replacement therapy (HRT), which consists of supplemental estrogen and progesterone. Those without a uterus (womb) sometimes took estrogen replacement therapy (ERT), which consists of supplemental estrogen alone. Only women who have had a hysterectomy usually take ERT, because taking estrogen without progesterone increases the risk of uterine cancer.
Taking HRT seemed to help reduce symptoms such as hot flashes, and it was thought that it also reduced a woman's risk of heart disease. But an important 2002 study, the Women's Health Initiative, found that HRT and ERT posed more risks than benefits. That study showed that women who took HRT for several years had an increased risk of breast cancer, heart disease, stroke, and blood clots. Women who took ERT long term (for more than 7 years) had a greater risk of stroke.
While the Women's Health Initiative didn't find a greater risk of breast cancer among women who took ERT for 7 years, other studies have found a slightly increased risk at 10 years. Right now the evidence shows that taking estrogen long-term slightly increases the risk for breast cancer, and taking it with progesterone increases the risk more.
Researchers have begun new studies to look at HRT, but the results aren't known yet. The Women's Health Initiative looked at women who were already past menopause (the average age was 63). So researchers don't know if the same results would apply to women who took HRT early in menopause, and for a shorter period of time. Currently, the decision about whether to take HRT is an individual one. If your menopause symptoms are so severe that they interfere with your daily life, talk to your doctor about the risks and benefits of using HRT for a short period of time.
In addition, there are non-hormonal medications and non-drug therapies that can help reduce your symptoms and lower your risk for long term medical problems that sometimes occur after menopause.
The benefits of exercise include:
Eating a healthy, well balanced diet can help you reduce the risks and discomforts associated with menopause. A diet low in saturated fat and cholesterol, for example, may reduce your risk of heart disease by providing the following benefits:
Some evidence suggests that eating soy based foods such as tofu might help reduce certain symptoms of menopause, including hot flashes. Adding plenty of calcium and vitamin D to your diet should help you avoid bone loss. (Foods rich in calcium include dairy products, leafy green vegetables, almonds, and dried beans). High-fiber foods may also help lower your risk of high cholesterol and heart disease.
Several medications are available to treat the symptoms of menopause and to help you maintain your health as you grow older.
Hormone replacement therapy (HRT) -- Your doctor may suggest using supplemental estrogen to provide relief from your symptoms depending on a number of factors, including your medical and family history, risk for hormone related cancers (such as breast cancer), age, and the severity of your symptoms. You and your doctor will carefully weigh the risks and benefits of HRT and prescribe the lowest dose of estrogen for your symptoms.
Low dose antidepressants -- Venlafaxine (Effexor), an antidepressant that is related to the class of drugs known as selective serotonin uptake reinhibitors (SSRIs), can help reduce hot flashes. Other SSRIs, such as fluoxetine (Prozac), sertraline (Zoloft), may also help.
Gabapentin (Neurontin) -- This drug, which is approved to treat seizures, also helps reduce hot flashes.
Bisphosphonates -- These drugs are used to prevent and treat osteoporosis. They reduce bone loss and the risk of fractures. They include:
Selective estrogen receptor modulators (SERMs) -- This type of drug has a positive effect on bone health, much like estrogen but without estrogen's side effects. Currently one drug, raloxifene (Evista), is approved for use. It can cause hot flashes, and should not be taken by anyone with a history of blood clots.
Vaginal estrogen -- Estrogen tablets, rings, or creams can be applied locally to relieve vaginal dryness.
The use of herbs is a time honored approach to strengthening the body and treating disease. Herbs, however, can trigger side effects and can interact with other herbs, supplements, or medications. For these reasons, you should take herbs with care, under the supervision of a health care practitioner. Treatments used to relieve menopause symptoms vary in their effectiveness from woman to woman. As with prescription medication taken to relieve menopause symptoms, some women may find relief with complementary therapies while others may not.
The flowing herbs are also sometimes suggested to relieve symptoms such as hot flashes, vaginal dryness, and mood swings, although evidence is mixed or lacking. Like soy, they may contain plant based estrogens (phytoestrogens) that could act like estrogen in the body and possibly raise the risk of breast cancer. Talk to your doctor before taking these herbs:
In the past, wild yam (Dioscorea villosa) has sometimes been mentioned as a treatment for menopausal symptoms, because hormones including progesterone were manufactured from wild yam in the 1960s. However, studies show that the body is not able to convert wild yam into progesterone, so it is not likely to help relieve any symptoms of menopause.
Several studies show acupuncture may help many women with symptoms of menopause, particularly with hot flashes and mood changes.
Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of menopause based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type. A constitutional type is defined as a person's physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for each individual.
Some studies suggest that learning to relax the body (through slow, deep breathing) may reduce the intensity of hot flashes.
As estrogen levels decline during menopause, a woman's risk of developing the following medical conditions may increase:
Menopause is part of the natural aging process for all women. There are many therapies available, however, to help ease the symptoms and reduce health risks associated with menopause. Selecting the right treatment for you can minimize discomfort and maximize the opportunities for a vital, healthy, satisfying life during and after menopause.
