Menopause is the time in a woman's life when her periods (menstruation) stop. It is a natural, normal body change that most often occurs between ages 45 - 55. After menopause, a woman can no longer become pregnant.
During menopause, a woman's ovaries stop making eggs. The body produces less of the hormones estrogen and progesterone. Lower levels of these hormones cause menopause symptoms.
Periods occur less often and eventually stop. Sometimes this happens suddenly. But most of the time, periods slowly stop over time.
Menopause is complete when you have not had a period for 1 year. This is called postmenopause. Surgical menopause takes place when surgical treatments cause a drop in estrogen. This can happen if your ovaries are removed.
Menopause can also sometimes be caused by drugs used for chemotherapy or hormone therapy for breast cancer.
Symptoms vary from woman to woman and can be worse for some than others.They may last 5 or more years. Symptoms may be worse for some women than others. Symptoms of surgical menopause can be more severe and start more suddenly.
