Menopause is a normal change in a woman’s life. It occurs when she has her last period. Menopause, however, doesn’t simply happen when menstruation ends—symptoms may begin years before your last period and continue for months or years after. The age at which menopause occurs varies, but the average age when a woman has her last period is 51. For some, however, menopause occurs in the forties or later in the fifties. |
Menopause in Depth

|
As you approach menopause, levels of estrogen and progesterone (female hormones produced in the ovaries) begin to change, or fall. These changing levels begin to cause the symptoms of menopause. This time of transition, which can start several years before your last period, is known as the menopausal transition or perimenopause. Perimenopause continues for a year after your last period. Once you haven’t had a period for one year, the next phase is called postmenopause, which lasts for the rest of your life.
Causes
Menopause and its symptoms are the result of changing levels of estrogen and progesterone. As mentioned earlier, menopause is a normal and natural part of life. There are, however, several outside factors that can lead to an early menopause. Smoking, for instance, can lead to an early menopause, as can surgeries to remove the uterus and/or ovaries. A hysterectomy, where the uterus is removed, will end menstruation, but won’t cause immediate symptoms of menopause; this is because the ovaries (which produce estrogen and progesterone) are not removed. If the ovaries are removed (an oophorectomy), which usually coincides with removal of the uterus, symptoms of menopause will also occur as menstruation ends.
Symptoms
Your body may go through many changes at midlife, and it’s not always clear which are caused by menopause and which are part of the aging process. Also, because estrogen is used by many parts of your body—not just your reproductive system—lower levels of estrogen can affect your health in several ways.
Changes commonly occurring at midlife that may be related to menopause include:
Related Health Concerns
Though they’re not symptoms of menopause, there are certain health concerns that can accompany the change as estrogen levels decrease and other changes related to aging occur. Two common concerns for women at midlife include osteoporosis and heart disease.
Osteoporosis. At the time of menopause, women may be at risk of osteoporosis, a condition where bones become weak and break easily. The body continually breaks down old bone and replaces it with new, healthy bone. Because estrogen helps control bone loss, when you lose estrogen during menopause, you body isn’t able to replace as much bone as it loses. Your doctor can test your bone density to determine your risk for osteoporosis as well as discuss ways to prevent or treat it.
Factors that increase risk for osteoporosis include:
Heart disease. A woman’s risk of heart disease increases after menopause. This is likely the result of changing estrogen levels and the aging process. Factors associated with increasing age—like weight-gain and high blood pressure—raise your risk of heart disease. See your doctor regularly to have your blood pressure and cholesterol levels checked and to discuss ways to keep your heart healthy.
Testing
There isn’t one clear method to determine when you’re in the menopausal transition or to predict when you may experience the change. You and your doctor may consider menopausal symptoms, a physical examination, medical history, and certain blood tests for clues about your status. Remember, however, that these are only clues—there’s no definitive test for menopause. Blood tests, for example, are unreliable because the hormones that your doctor may measure—such as estrogen and follicle-stimulating hormone—normally rise and fall during your menstrual cycle.
Treatments
Menopause is a natural change in life, so “treatment” during menopause actually involves treating not menopause itself but the symptoms of menopause and related health concerns. Staying healthy during and beyond menopause is also about more than just making it through this transition—considering that today’s average woman has more than one-third of her life ahead of her after menopause, this is a great time to take action to improve and protect your health.
Managing symptoms of menopause can begin with lifestyle changes designed to improve and maintain your general health; these include:
You can also directly address some of the symptoms of menopause and related health concerns by doing the following:
There are several things you can do to manage hot flashes. Consider the following:
Menopausal Hormonal Therapy
There has been much debate surrounding the use of menopausal hormonal therapy (MHT) to relieve some of the symptoms of menopause and to prevent bone loss around the time of menopause.
Though some women find that taking estrogen (and progesterone, among those who still have a uterus) does provide relief of symptoms like hot flashes, night sweats, and vaginal dryness, there are also risks associated with MHT. Studies have suggested that major health concerns associated with use of MHT include an increased risk of breast cancer and ovarian cancer and cardiovascular risks. Risk varies by type of MHT used (estrogen-plus-progestin versus estrogen alone). Talk with your doctor to determine what type of MHT might be right for you and about its risks and benefits. To minimize these risks, the U.S. Food and Drug administration (FDA) advises that if you choose to try MHT, you do so for the shortest time needed and use the lowest effective dose. Know that your symptoms may return when you stop taking the hormones.
In addition to serious medical concerns associated with MHT, some women also experience additional side effects. These include breast tenderness, spotting or a return of monthly periods, cramping, and bloating. These side effects will sometimes go away on their own or may be alleviated by changing the dose or timing of MHT.
Birth Control Pills
Doctors sometimes recommend birth control pills during perimenopause. Birth control pills can help manage heavy, frequent, or unpredictable periods and can prevent pregnancy. As well, they may help relieve symptoms like hot flashes.
Alternative Approaches
Phytoestrogens. Some women look to non-medical methods to manage the symptoms of menopause. One approach is to increase dietary intake of phytoestrogens, which might work in the body like a weak form of estrogen. These estrogen-like substances are found in food sources including some cereals, vegetables, legumes (soy, for example), and herbs and can also be taken as an herbal supplement. The ability of phytoestrogens to relieve symptoms of menopause, however, has not been determined, and there may be risks associated with their use. It’s important that your talk to your doctor if you’re thinking about eating more foods rich in phytoestrogens or using a supplement.
Bioidentical or “natural hormones.” Estrogen and progesterone can be made from plants such as soy or yams; these so-called natural hormones are supposed to closely resemble hormones naturally produced by the body. A doctor determines the formula for each patient, and a pharmacist puts it together in a process call compounding. There is little data about the safety or efficacy of natural hormones, as they are not regulated or approved by the FDA.
