Symptoms of Uterine Fibroids

Some people have fibroids that do not cause symptoms. If a fibroid does cause symptoms, it may be because of the size or location.

Symptoms range from mild to severe. Large fibroids can cause:

  • Pelvic pain or pressure
  • Low back or leg pain
  • Pain during sex
  • A frequent need to pass urine
  • Constipation—a problem passing stool
  • Belly swelling or bloating
  • Infertility
  • Miscarriage

Bleeding symptoms are:

  • Heavy menstrual bleeding
  • Blood clots in menstrual flow
  • Long periods
  • Bleeding between periods
  • Increased cramping during periods

Bleeding that lasts a long time can lead to iron-deficiency anemia. This can cause:

  • Lack of energy and strength
  • Shortness of breath
  • Pale skin
  • Lightheadedness
