Secondary amenorrhea occurs when a woman who has been having normal menstrual cycles stops getting her periods for 6 or more months.
Amenorrhea is when a woman does not get her monthly menstrual cycle, or period.
Women who are pregnant, breastfeeding, or in menopause are not considered to have secondary amenorrhea.

Treatment depends on the cause of the amenorrhea. Normal monthly periods usually return after the condition is treated.

The outlook depends on the cause of amenorrhea. Most of the conditions that cause secondary amenorrhea will respond to treatment.
Complications depend on the cause of the condition. Amenorrhea may be harmless, or it may be associated with overgrowth of the uterine lining (endometrial hyperplasia). This can sometimes lead to uterine cancer.
There may be other complications, depending on the cause of the amenorrhea.
Call for an appointment with your primary health care provider or OB/GYN provider if you have missed more than one period so that you can get diagnosed and treated, if necessary.
Prevention depends on the cause. For example, moderate exercise instead of extreme exercise, weight control, and other measures may be helpful.
