Menopause is one of the hottest topics among women aged 40 and older, no pun intended. But talk around this topic can get a little confusing.
The term “menopause” is often used as a catch-all term for hormonal and body changes women experience at mid-life as the body’s reproductive system starts to shut down. But true menopause happens when you have not had a menstrual period or spotting for 12 months in a row, according to the National Institute of Aging (NIA). After that, you’re considered postmenopausal.
So, just how long does menopause last? The short answer: The overall “menopause transition” lasts, on average, several years — but the exact timeline varies from woman to woman. Below, we break down the stages of menopause and what you may experience in each.
The stages of menopause
Think of menopause as a timeline. Perimenopause is the period before the body changes and symptoms leading up to menopause. Menopause is the main event. Post-menopause is what comes after.
Perimenopause
For most women, perimenopause starts between the ages of 45 and 55. You may also hear it called the “menopausal transition.”
During perimenopause, levels of estrogen and progesterone — hormones made by the ovaries — begin to fluctuate and trend downward. Ovulation may happen less often, making it more difficult to get pregnant (but still possible).
Your menstrual cycle also starts to change. You may have lighter or heavier bleeding. Your menstrual cycles may get shorter, or your periods may come closer together. You may have spotting between periods.
Perimenopause can cause a range of symptoms that can disrupt your quality of life:
- Anxiety and depression.
- Moodiness and irritability.
- Memory changes and focus problems.
- Hot flashes and night sweats.
- Trouble sleeping.
- Bladder problems.
- Hair loss.
- Joint and muscle aches.
- Sexual problems, like pain during sex or loss of interest.
- Vaginal dryness.
Symptoms often last between two and eight years, according to the NIA. Some women may have mild symptoms or none at all.
Menopause
You reach menopause when you have not had your period for 12 months in a row. It marks the point at which the ovaries no longer produce, mature, or release eggs.
The average age for menopause is 52, according to the Office of Women’s Health. Sometimes menopause happens much earlier than expected:
Premature menopause: menopause that occurs before age 40. The medical term is primary ovarian insufficiency, or POI. It happens when your ovaries stop working earlier than normal. Irregular periods, reduced fertility, and perimenopause symptoms start before age 40. Sometimes these changes can happen during your teen years. In about 90% of cases, doctors don’t know the exact cause.
Early menopause: 5% of women experience menopause that happens between the ages of 40 and 45.
Some women go into sudden or “crash” menopause, often due to cancer treatment or surgery to remove the ovaries or uterus. Factors linked to earlier menopause may include:
- Family history of premature or early menopause.
- Smoking.
- Race. Black women are more likely to enter menopause early, according to the NIA.
- Certain health conditions. This includes autoimmune diseases, such as rheumatoid arthritis and thyroid disease, chronic fatigue syndrome, untreated HIV/AIDS, and missing chromosomes.
If you think menopause is starting unusually early, talk with your healthcare provider. They can evaluate symptoms, review your health history, and order hormone testing when appropriate.
Post-menopause
Post-menopause begins after menopause is reached. Some symptoms (like hot flashes) may improve over time, but they can persist for years in some women, according to the OASH.
Because the ovaries now produce very little estrogen, you are at increased risk of certain health problems. This includes:
- Osteoporosis, a condition in which bones become brittle and weak and break easily.
- Heart disease.
- Stroke.
- Weight gain.
When to talk to your doctor
Women should talk to their doctor about their menstrual and reproductive health during annual wellness exams. As you go through perimenopause and menopause, your doctor can help you stay healthy. Different treatment options can help prevent some symptoms and reduce others. If your doctor doesn’t mention your menstrual health, speak up or ask for a referral for a women’s health specialist, such as an OB/GYN.
Schedule an appointment with your doctor if:
- You have bothersome menopause-related symptoms that are disrupting your daily life. Depending on your symptoms, medications and other options may help.
- You notice irregular periods or other perimenopause symptoms that start before age 45. Your doctor can check your hormone levels. It can also help you know whether you can still get pregnant.
- You have any vaginal bleeding or spotting after menopause. It may point to something benign, like a urinary tract infection. In rare cases, however, spotting after menopause may be a sign of ovarian or other gynecological cancers.
Menopause may be a natural part of aging, but for some women, it can come with unpleasant symptoms that make life challenging. Speaking up can get you the help you need.
