What’s Behind Your Heavy Periods

There are a lot of reasons for having heavy periods, or AUB. Some of them include1:

  • Fibroids

    in the uterus, which are noncancerous tissue growths in the muscle walls of the uterus.

  • Polyps

    in the uterus, which are small, protruding bits of tissue that grow on the lining of the uterus.

  • An imbalance of the hormones,

    estrogen or progesterone. These hormones can build up the endometrium (the lining in your uterus), which is shed during your period. That thicker lining can result in heavier blood flow.2

  • Other diseases or disorders

    like pelvic inflammatory disease (PID), thyroid disease, liver or kidney disease, or bleeding disorders like von Willebrand disease (characterized by an impaired ability of the blood to clot).¹

  • Rarely,

    heavy bleeding could be related to cancer of the uterus or cervix.1 The risk is greater for women who are overweight, as this can lead to hormone imbalances.2
