Menorrhagia
（重定向自Hypermenorrhea）
Menorrhagia is a menstrual period with abnormally heavy flow and falls under the larger category of abnormal uterine bleeding (AUB).
Abnormal uterine bleeding can be caused by structural abnormalities in the reproductive tract, anovulation, bleeding disorders, or cancer of the reproductive tract. Initial evaluation aims at figuring out pregnancy status, menopausal status, and the source of bleeding.
