  • Pelvic infections
  • Bleeding disorders, such as von Willebrand disease
  • Medicine that slows blood clotting
  • Anti-inflammatory medicine
  • Liver, kidney, or thyroid disease
  • Hormonal imbalance
  • Ovarian cyst
  • Intrauterine device (IUD)

Risk Factors

Menorrhagia is more common in:

  • Teens to early adulthood
  • Women who are close to menopause

Symptoms

Menorrhagia may be:

  • Bleeding that lasts more than 7 days
  • Very heavy bleeding (soaking through a sanitary napkin or tampon every hour)
  • Flow that needs change of sanitary napkin during the night
  • Large clots
