One of the most common symptoms of fibroids is heavy periods. A normal menstrual cycle normally occurs every 25-31 days and lasts from 3-7 days.
A common cause of heavy periods are uterine fibroids. Myomas are the most common non-cancerous tumors in women (about one-third of U.S. women between ages 25 and 44 report having symptoms of fibromas). Fibroids can be different in size, quantity, and location. While some women do not experience any symptoms, others have a variety of symptoms (pelvic and back pain, heavy and prolonged menstrual bleeding, enlarged uterus, and in some cases, infertility).
If fibroids are near the uterine lining, or interfere with the blood flow to the lining, they can cause heavy periods, painful periods, prolonged periods or spotting between periods.
