Menorrhagia is the medical term for abnormally heavy or prolonged bleeding. Although heavy bleeding is common among women, it is usually not severe enough to be considered menorrhagia.
With menorrhagia, every period you have causes enough blood loss and cramping that you can’t maintain your usual activities.
There are various causes for menorrhagia including hormone imbalance problems, uterine fibroids, negative reaction to an IUD, and other medical conditions. Treatment for abnormal bleeding depends on the cause.
If you have menstrual bleeding so heavy that you dread your period, talk with your doctor. There are many effective treatments for menorrhagia.
