Dysfunctional uterine bleeding (DUB) is abnormal uterine bleeding in terms of amount, duration, or timing during the menstrual cycle, with no discernible organic cause. The normal menstrual cycle is dependent on the influence of four hormones: estrogen, which predominates during the proliferative phase (generally days 1 to 14); progesterone, which predominates during the secretory phase (generally days 15 to 28); and follicle-stimulating hormone (FSH) and luteinizing hormone (LH), both of which stimulate the ovarian follicle to mature. Disrupting the balance of these four hormones usually results in anovulation and DUB. During an anovulatory cycle, the corpus luteum does not form and thus progesterone is not secreted. Failure of progesterone secretion allows continuous unopposed production of estradiol, which stimulates the overgrowth of the endometrium. This results in an overproduction of the uterine blood flow. Complications of DUB include anemia, infection from prolonged use of tampons, and in rare situations, hemorrhagic shock. As many as 10% of women with normal ovulatory cycles experience DUB.
