Menorrhagia

Abnormally profuse or prolonged menstrual bleeding at regular menstrual intervals, often resulting in excessive blood loss that may lead to iron-deficiency anemia or hemodynamic compromise if severe or chronic. Possible causes are hormonal imbalances (PCOS, thyroid disease), uterine fibroids, uterine polyps, adenomyosis, pregnancy complications (miscarriage, ectopic pregnancy), bleeding disorder (von Willebrand's disease), medications (anticoagulants, NSAIDs), pelvic inflammatory disease, endometriosis, and liver/kidney failure.
