Menstruation, cessation of

Menstruation, cessation of: Menstruation ends naturally in middle age with the onset of the menopause. It can also end suddenly as a result of induced menopause. Cessation of menstruation in non-menopausal women may be due to pregnancy, illness, disorders of the hypothalamus or pituitary gland, medication, stress, overexercise, or malnutrition, among other causes. In particular, it can be a symptom of anorexia, signaling potentially dangerous changes in the body's hormonal system. Cessation of menstruation in women who have established a regular menstrual cycle, or in girls or teens who show other signs of anorexia, is always a cause for medical concern. Also known as amenhorrhea.
