The Basics of Menstrual Disorders

The Basics of Menstrual Disorders <i>(cont'd)</i>

Other hormonal causes of dysfunctional uterine bleeding include thyroid or adrenal gland imbalance. Heavy bleeding may be caused by medical conditions, such as:

  • blood clotting disorders such as Von Willebrand's disease, ITP or hemophilia
  • liver or kidney disease
  • leukemia
  • medications, such as anticoagulant drugs and some synthetic hormones
  • the Copper-T IUD, which may also cause heavy periods
  • normal pregnancy
  • miscarriage
  • ectopic pregnancy, which occurs when a fertilized egg begins to grow outside your uterus, typically in your fallopian tubes
  • chronic medical problems, such as diabetes, lupus or sarcoidosis

Structural causes of excessive bleeding include:

  • polyps
  • scar tissue
  • infection
  • pre-cancerous conditions
  • uterine fibroids

Fibroids don't always cause excessive bleeding. In fact, about half of all women who have fibroids don't have any symptoms at all.
