Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding. Although heavy menstrual bleeding is a common concern among premenopausal women, most women don't experience blood loss severe enough to be defined as menorrhagia.
With menorrhagia, every period you have causes enough blood loss and cramping that you can't maintain your usual activities. If you have menstrual bleeding so heavy that you dread your period, talk with your doctor. There are many effective treatments for menorrhagia.

Your doctor will do a physical exam and may recommend one or more tests or procedures such as:

Excessive or prolonged menstrual bleeding can lead to other medical conditions, including:
Iron deficiency anemia. In this common type of anemia, your blood is low in hemoglobin, a substance that enables red blood cells to carry oxygen to tissues. Low hemoglobin may be the result of insufficient iron.
Menorrhagia may decrease iron levels enough to increase the risk of iron deficiency anemia. Signs and symptoms include pale skin, weakness and fatigue. Although diet plays a role in iron deficiency anemia, the problem is complicated by heavy menstrual periods.
Most cases of anemia are mild, but even mild anemia can cause weakness and fatigue. Moderate to severe anemia can also cause shortness of breath, rapid heart rate, lightheadedness and headaches.

Menorrhagia is most often due to a hormone imbalance that causes menstrual cycles without ovulation. In a normal cycle, the release of an egg from the ovaries stimulates the body's production of progesterone, the female hormone most responsible for keeping periods regular. When no egg is released, insufficient progesterone can cause heavy menstrual bleeding.
Menstrual cycles without ovulation (anovulatory cycles) are most common among two separate age groups:
