Abnormal uterine bleeding.
Disorders of the menstrual cycle are common problems in ambulatory medicine. Abnormal uterine bleeding describes bleeding that is excessive or outside the normal menstrual cycle. In the premenopausal woman, the differential diagnosis is broad, and pregnancy must always be considered. Determining whether the bleeding is ovulatory or anovulatory is a central part of the evaluation, as anovulation is one of the most common causes of abnormal uterine bleeding. In patients with anovulatory bleeding, the goal of treatment is to minimize blood loss and prevent complications from chronic unopposed estrogen. In women with oligomenorrhea or amenorrhea, after establishing the etiology, it is necessary to maintain adequate estrogen to support bone health. In the peri- and postmenopausal population, because the incidence of endometrial hyperplasia and malignancy rises, it is important to have a low threshold for endometrial assessment.
