Causes
There are many causes of menorrhagia. A hormonal imbalance between progesterone and estrogen might cause excessive development of the uterus lining, which will be shed during a menstrual cycle and trigger heavy bleeding. Another possible trigger is a dysfunctional ovary, meaning that the body does not produce sufficient progesterone hormone during the period. Also, noncancerous growths like fibroids or polyps may increase the risk of prolonged and abnormally heavy bleeding. Women with pregnancy complications, such as miscarriage or placenta previa, tend to be at a higher risk of experiencing menorrhagia than others. Some other possible causes include adenomyosis, side effects of birth control or medications, cancer, genetic bleeding disorders, and medical conditions like kidney or liver disease. [5]
