Weight gain is not a symptom associated with uterine fibroids, according to WebMD. Potential symptoms of uterine fibroids include heavy menstrual periods, prolonged bleeding, frequent urination, and pelvic or abdominal pain and swelling.
Although they are sometimes referred to as fibroid tumors, uterine fibroids have a very small chance of being cancerous, according to WebMD. Uterine fibroids can be located under the uterine lining, between the muscles in the uterine wall, or on the uterine wall and into the pelvic cavity. Treatment of uterine fibroids is based upon the patient's age, symptoms, childbearing potential and the size, location and number of fibroids.
