What is menopause?
Menopause is the time in your life when you naturally stop having menstrual periods. Menopause happens when the ovaries stop making estrogen. Estrogen is a hormone that helps control the menstrual cycle. Menopause marks the end of the reproductive years. The average age that women go through menopause is 51 years.
What is perimenopause?
The years leading up to menopause are called perimenopause. Beginning in your 30s and 40s, the amount of estrogen produced by the ovaries begins to fluctuate. A common sign of perimenopause is a change in your menstrual cycle. Cycles may become longer than usual for you or become shorter. You may begin to skip periods. The amount of flow may become lighter or heavier. Although changes in menstrual bleeding are normal during perimenopause, you still should report them to your health care provider. Abnormal bleeding may be a sign of a problem.
Besides menstrual cycle changes, what other signs and symptoms can occur during perimenopause?
Some women do not have any symptoms of perimenopause or have only a few mild symptoms. Others have many symptoms that can be severe. Common signs and symptoms include the following:
What types of bone changes can occur after menopause?
A small amount of bone loss after age 35 years is normal for both men and women. But during the first 4–8 years after menopause, women lose bone more rapidly. This rapid loss occurs because of the decreased levels of estrogen. If too much bone is lost, it can increase the risk of osteoporosis. Osteoporosis increases the risk of bone fracture. The bones of the hip, wrist, and spine are affected most often.
