Menorrhagia

Causes of Menorrhagia

There are a number of potential causes of menorrhagia, although in most cases the cause of recurrent menorrhagia is unclear. These causes include:

  • A hormonal imbalance of estrogen and progesterone, most commonly among adolescent girls experiencing their first period and woman approaching menopause
  • Pelvic inflammatory disease
  • Noncancerous growths or tumors of the uterus called uterine fibroids or polyps
  • Certain birth control devices, such as intrauterine devices
  • Inherited bleeding disorders, such as von Willebrand disorder, or platelet disorders
  • Cancer of the uterus or cervix
  • Pregnancy complications, such as miscarriage or ectopic pregnancy
  • Adenomyosis, or uterine thickening that occurs when endometrial tissue moves into the outer muscular walls of the uterus
  • Dysfunction of the ovaries
  • Medications such as warfarin, which is used to prevent blood clots, and some drugs taken for chemotherapy; aspirin can also cause increased bleeding
  • Age can also play a role: women over 40 who develop heavy periods may require additional tests to try to uncover the underlying cause of their menorrhagia
