What causes heavy periods. Diagnosing what causes heavy periods can sometimes be difficult. However, some physical condition affecting the uterus, such as fibroids and polyps, may cause heavy menstrual bleeding. The more common reasons for heavy periods are: 1  fibroids. 2  polyps.  endometrial hyperplasia.
The whole process then repeats again. Heavy menstrual bleeding can occur when there is some imbalance in these hormones. This imbalance prevents the release of the egg from the ovary, causes a buildup of the lining of the uterus, and results in an instability of the lining which makes it more prone to shedding.
