Heavy Periods- Causes

Heavy Periods- Causes
No underlying cause is identified in 40-60% of cases of heavy periods (menorrhagia).

Otherwise, possible causes of heavy periods include the following:

  • cervical or endometrial polyps – non-cancerous growths in the womb or lining of the cervix (neck of the womb)
  • endometriosis – when small pieces of the womb lining are found outside the womb, such as in the fallopian tubes, ovaries, bladder or vagina
  • uterine fibroids – non-cancerous growths in the womb that can cause pelvic pain
  • (also known as “the coil”) – blood loss may increase by 40-50% after an IUD is inserted
  • pelvic inflammatory disease (PID) – an ongoing infection in the pelvis that can cause pelvic pain, fever and bleeding after sexual intercourse or between periods
  • polycystic ovary syndrome (PCOS) – women with PCOS typically have a number of cysts in their ovaries
  • blood clotting disorders such as von Willebrand disease
  • adenomyosis – when glands from the lining of the uterus become embedded in the uterus muscle
  • an – this may cause fatigue, constipation, intolerance to cold, and hair and skin changes
  • liver or kidney disease
  • cancer of the womb (although this is very rare)

Treatments that can cause heavy periods
Heavy periods may sometimes be caused by medical treatments. These can include:

  • anticoagulant medicines (medication to reduce the ability of the blood to clot)
