Amenorrhea is considered a type of abnormal menstrual bleeding characterized by the unexpected absence of menstrual bleeding, lasting three months or longer. Menstrual bleeding typically happens approximately once a month when blood and endometrial tissue, or tissue lining the inside of the uterus, sheds from the uterus through the vagina. Menstruation is expected to stop with pregnancy, breastfeeding, and menopause, or the natural cessation of the menstrual cycle at an older age. However, women may also experience amenorrhea because of an underlying health condition, including low body weight or polycystic ovarian syndrome, that may complicate fertility and contribute to decreased quality of life. According to the American College of Obstetricians and Gynecologists, one in twenty-five women experience amenorrhea as a menstrual disorder within their lives at times.
