Menometrorrhagia: Excessive uterine bleeding, both at the usual time of menstrual periods and at other irregular intervals. Menometrorrhagia can be a sign of a number of different disorders including hormone imbalance, endometriosis, benign fibroid tumors in the uterus, and, less commonly, cancer. Women who have abnormal menstrual bleeding should always consult their physician to rule out these conditions. Anemia may result from the excessive uterine bleeding. Treatment depends on the cause. If there does not appear to be a dangerous cause, such as cancer, hormone supplementation, the therapeutic use of birth control pills to better control the menstrual cycle, or fibroid removal (myomectomy) may be recommended. Hysterectomy may sometimes be required. See also: Menorrhagia; Metrorrhagia.
