What causes HMB?

For up to 60% of women with HMB, there is no obvious cause. However some conditions have been linked to HMB, including:

  • Polycystic ovary syndrome (PCOS)A common condition caused by an imbalance of reproductive hormones that affects how a woman's ovaries work
  • Pelvic inflammatory disease (PID)An infection in the upper genital tract (the womb, fallopian tubes or ovaries) that can cause pelvic or abdominal pain and bleeding after sex or between periods
  • FibroidsNon-cancerous growths that develop in or around the womb
  • EndometriosisWhen small pieces of the womb lining are found outside the womb, such as in the fallopian tubes, ovaries, bladder or vagina
  • HypothyroidismAn underactive thyroid, where the thyroid gland doesn't produce enough hormones, causing tiredness, weight gain and feelings of depression
  • Cervical or endometrial polypsNon-cancerous growths in the lining of the womb or cervix (neck of the womb)
  • Blood clotting disorders
  • Cancer of the womb

It is important to note that, whether or not a direct cause can be found, HMB is usually a highly treatable condition and there are choices available for you to discuss with your GP.
