Abnormal uterine bleeding (AUB) is the cause of roughly one-third of all visits to the gynecologist among premenopausal women and more than 70 percent of office visits among peri- and postmenopausal women.
A normal menstrual cycle typically lasts between 21 and 35 days, with menstruation generally lasting for five days. AUB describes bleeding that is more or less frequent or heavier than normal or menstrual cycles that are shorter or longer than average. In reproductive-age women, causes of AUB can vary greatly and may include uterine fibroids or polyps, irregular ovulation, hormonal contraception, endometrial problems, underlying bleeding disorders such as von Willebrand disease, or cancer. Isolating the cause of AUB can help in developing an appropriate treatment or management plan.
The American College of Obstetricians and Gynecologists’ recommendations address diagnosis of AUB using a thorough medical history and physical exam, appropriate laboratory and imaging tests, and considerations of age-related factors.
