1.2. Menopause

What is menopause?

Menopause is the point in time when a woman's menstrual periods stop. Some people call the years leading up to a woman's last period "menopause," but that time actually is perimenopause (PER-ee-MEN-oh-pawz).

Periods can stop for a while and then start again, so a woman is considered to have been through menopause only after a full year without periods. (There also can't be some other reason for the periods stopping like being sick or pregnant.) After menopause, a woman no longer can get pregnant. It is common to experience symptoms such as hot flashes in the time around menopause.

The average age of menopause is 51, but for some women it happens in their 40s or later in their 50s. Sometimes called "the change of life," menopause is a normal part of life.

What is perimenopause?

Perimenopause (PER-ee-MEN-oh-pawz), which is sometimes called "the menopausal transition," is the time leading up to a woman's last period. During this time a woman will have changes in her levels of the hormones estrogen (ES-truh-jin) and progesterone (proh-JES-tuh-RONE). These changes may cause symptoms like hot flashes. Some symptoms can last for months or years after a woman's period stops. After menopause, a woman is in postmenopause, which lasts the rest of her life.

What symptoms might I have before and after menopause?

When to see a doctor

Do not assume that if you miss a couple of periods the cause is menopause. See your doctor to find out if pregnancy or a health problem could be the cause. Also see your doctor if you have not had a period for a year and then start "spotting."

The hormone changes that happen around menopause affect every woman differently. Also, symptoms sometimes are not caused by menopause but by other aspects of aging instead.

Some changes that might start in the years around menopause include:


How will I know when I am nearing menopause?

Symptoms, a physical exam, and your medical history can provide clues that you are in perimenopause. Your doctor also could test the amount of hormones in your blood. But hormones go up and down during your menstrual cycle, so these tests alone can't tell for sure that you have gone through menopause or are getting close to it.


How can I manage symptoms of menopause?

It is not necessary to get treatment for your symptoms unless they are bothering you. You can learn about simple lifestyle changes that may help with symptoms, and some symptoms will go away on their own. If you're interested in medical treatments like menopausal hormone therapy (MHT), ask your doctor about the possible risks and benefits.

Here are some ways to deal with symptoms:

Hot flashes

Vaginal dryness

Problems sleeping

Mood swings

Memory problems

Urinary incontinence


Does menopause cause bone loss?

Lower estrogen around the time of menopause leads to bone loss in women. Bone loss can cause bones to weaken, which can cause bones to break more easily. When bones weaken a lot, the condition is called osteoporosis (OSS-tee-oh-puh-ROH-suhss).

To keep your bones strong, women need weight-bearing exercise, such as walking, climbing stairs, or using weights. You can also protect bone health by eating foods rich in calcium and vitamin D, or if needed, taking calcium and vitamin D supplements. Not smoking also helps protect your bones.

Ask your doctor if you need a bone density test. Your doctor can also suggest ways to prevent or treat osteoporosis.


Does menopause raise my chances of getting cardiovascular disease?

Yes. After menopause, women are more likely to have cardiovascular (kar-dee-oh-VAS-kuh-lur) problems, like heart attacks and strokes. Changes in estrogen levels may be part of the cause, but so is getting older. That's because as you get older, you may gain weight and develop other health problems that increase your risk of cardiovascular disease (CVD).

Ask your doctor about important tests like those for cholesterol and high blood pressure. Discuss ways to prevent CVD. The following lifestyle changes also can help prevent CVD:


Can menopausal hormone therapy (MHT) help treat my symptoms?

MHT, which used to be called hormone replacement therapy (HRT), involves taking the hormones estrogen and progesterone. (Women who don't have a uterus anymore take just estrogen). MHT can be very good at relieving moderate to severe menopausal symptoms and preventing bone loss. But MHT also has some risks, especially if used for a long time.

MHT can help with menopause by:

For some women, MHT may increase their chance of:

Research into the risks and benefits of MHT continues. For example, a recent study suggests that the low-dose patch form of MHT may not have the possible risk of stroke that other forms can have. Talk with your doctor about the positives and negatives of MHT based on your medical history and age. Keep in mind, too, that you may have symptoms when you stop MHT. You can also ask about other treatment options. Lower-dose estrogen products (vaginal creams, rings, and tablets) are a good choice if you are bothered only by vaginal symptoms, for example. And other drugs may help with bone loss.

If you choose MHT, experts recommend that you:

If you take MHT, call your doctor if you develop any of the following side effects:


Who should not take MHT for menopause?

Women who:


Can MHT prevent heart disease or Alzheimer's disease?

A major study called the Women's Health Initiative (WHI) has looked at the effects of MHT on heart disease and other health concerns. It has explored many questions relating to MHT, including whether MHT's effects are different depending on when a woman starts it. Learn more about MHT research results External link.

Future research may tell experts even more about MHT. For now, MHT should not be used to prevent heart disease, memory loss, dementia, or Alzheimer's disease. MHT sometimes is used to treat bone loss and menopausal symptoms. Learn more in Can menopausal hormone therapy (MHT) help my symptoms?


Are there natural treatments for my symptoms?

Some women try herbs or other products that come from plants to help relieve hot flashes. These include:

Make sure to discuss any natural or herbal products with your doctor before taking them. It's also important to tell your doctor about all medicines you are taking. Some plant products or foods can be harmful when combined with certain medications.


What is "bioidentical" hormone therapy?

Bioidentical hormone therapy (BHT) means manmade hormones that are the same as the hormones the body makes. There are several prescription BHT products that are well-tested and approved by the U.S. Food and Drug Administration (FDA).

Often, people use the term "BHT" to mean medications that are custom-made by a pharmacist for a specific patient based on a doctor's order. These custom-made products are also sometimes called bioidentical hormone replacement therapy (BHRT). Despite claims, there is no proof that these products are better or safer than drugs approved by the FDA. Also, many insurance and prescription programs do not pay for these drugs because they are viewed as experimental.


How much physical activity do I need as I approach menopause?

Physical activity helps many areas of your life, including mood, sleep, and heart health. Aim for:

If you are not able to follow these guidelines, be as physically active as you can. Your doctor can help you decide what's right for you.


Do I need a special diet as I approach menopause?

A balanced diet will give you most of what your body needs to stay healthy. Here are a few special points to consider:


I'm having a hysterectomy soon. Will this cause menopause?

A woman who has a hysterectomy (his-tur-EK-tuh-mee) but keeps her ovaries does not have menopause right away. Because your uterus is removed, you no longer have periods and cannot get pregnant. But your ovaries might still make hormones, so you might not have other signs of menopause. You may have hot flashes because the surgery may affect the blood supply to the ovaries. Later on, you might have natural menopause a year or two earlier than usually expected.

A woman who has both ovaries removed at the same time that the hysterectomy is done has menopause right away. Having both ovaries removed is called a bilateral oophorectomy (OH-uh-fuh-REK-tuh-mee). Women who have this operation no longer have periods and may have menopausal symptoms right away. Because your hormones drop quickly, your symptoms may be stronger than with natural menopause. If you are having this surgery, ask your doctor about how to manage your symptoms.

Menopause that is caused by surgery also puts you at risk for certain conditions, such as bone loss and heart disease. Ask your doctor about possible steps, including MHT, to help prevent these problems.


What if I have symptoms of menopause before age 40?

Some women have symptoms of menopause and stop having their periods much earlier than expected. This can happen for no clear reason, or it can be caused by:

When menopause comes early on its own, it sometimes has been called "premature menopause" or "premature ovarian failure." A better term is "primary ovarian insufficiency," which describes the decreased activity in the ovaries. In some cases, women have ovaries that still make hormones from time to time, and their menstrual periods return. Some women can even become pregnant after the diagnosis.

For women who want to have children and can't, early menopause can be a source of great distress. Women who want to become mothers can talk with their doctors about other options, such as donor egg programs or adoption.

Early menopause raises your risk of certain health problems, such as heart disease and osteoporosis. Talk to your doctor about ways to protect your health. You might ask about menopausal hormone therapy (MHT). Some researchers think the risks of MHT for younger women might be smaller and the benefits greater than for women who begin MHT at or after the typical age of menopause.

Let your doctor know if you are younger than 40 and have symptoms of menopause.
