The causes of menorrhagia may be classified into:

  • pelvic pathology:
    • pelvic endometriosis
    • pelvic inflammatory disease
    • endometrial hyperplasia
    • uterine fibroids
  • systemic disorders:
    • hypothyroidism - but usually presents with amenorrhoea in advanced cases
    • blood clotting disorders - very rare; examples include von Willebrand's disease, thrombocytopenia
  • iatrogenic factors:
    • intra-uterine contraceptive device
    • misoprostol
    • poorly-controlled anticoagulant therapy
  • psychosomatic disturbance - usually subsides when precipitating factors subside
  • dysfunctional uterine bleeding - if all other local and systemic causes have been excluded
