Many, if not most, fibroids cause no symptoms. The ones that cause symptoms do so either because they are large or because of their location.

Symptoms range from mild to severe, depending on the size and location of the growths. Large fibroids can produce symptoms such as:

  • Pelvic pain
  • Low back or leg pain
  • Feeling of pelvic pressure
  • Pain during sex
  • Frequent need to urinate
  • Constipation
  • Bloating
  • Enlarged uterus, giving the appearance of pregnancy
  • Infertility by blocking the fallopian tubes

Bleeding symptoms include:

  • Heavy menstrual bleeding
  • Clots in your menstrual flow
  • Long periods
  • Bleeding between periods
  • Increased cramping during periods
  • Miscarriage

If heavy bleeding continues for a period of time, iron-deficiency anemia may develop. Symptoms of anemia include:

  • Weakness
  • Fatigue
  • Shortness of breath
  • Pale skin
  • Lightheadedness
