Menorrhagia is a medical condition where there are abnormally heavy menstrual periods or prolonged menstrual bleeding. This may be common in some women, but the blood loss should not be so severe enough to cause a lot of blood loss.
Menorrhagia may be so severe that it can disrupt your normal activities. The menstrual period can be so heavy and may last for many days. There may also be painful menstrual cramping.
