Menorrhagia

Excessive loss of blood during menstruation. Menorrhagia may be caused by an imbalance of oestrogen hormones and progesterone hormone, which control menstruation. The imbalance causes an excessive build-up of endometrium (lining of the uterus). Disorders that affect the uterus, such as fibroids, polyps, or a pelvic infection, can also cause menorrhagia. Treatment may include nonsteroidal anti-inflammatory drugs, drugs that affect blood clotting, hormones, or the fitting of an IUD (intrauterine device) that releases small amounts of progestogen. Menorrhagia may also be treated by endometrial ablation.
