Menorrhagia is defined as excessive menstrual bleeding either in duration or volume, typically exceeding 80 mL per cycle or lasting more than 7 days. This condition can lead to significant anemia and impact a woman’s quality of life. It differs from dysmenorrhea, which refers to painful menstruation, and from other menstrual disorders like irregular cycles or absence of menstruation. Recognizing menorrhagia is crucial for appropriate diagnosis and management, which may include medical or surgical interventions such as endometrial ablation or hysterectomy for refractory cases.
