Menorrhagia is a condition that is defined by an abnormally heavy or prolonged period of menstrual bleeding. In a normal menstrual period, about 2 ounces of blood is lost. With menorrhagia, a woman may lose 3 ounces or more. The presence of menorrhagia does not necessarily signify a serious underlying disorder.
Causes of Menorrhagia
Menorrhagia is seen with anovulation, or the failure to release an egg each month. Uterine fibroids, which are tumors of the muscular layer of the uterus, can produce excessive menstrual bleeding. Pelvic infections can lead to menorrhagia. Endometrial infections or cancers can lead to excessive bleeding. The use of an IUD and hypothyroidism, both, can lead to excessive menstrual bleeding.
