What Causes Heavy Periods

Hormonal imbalances

Hormonal imbalances occur when a woman is not producing the right balance of estrogen and progesterone. It is very common, especially when a woman begins or ends her reproductive years. This imbalance may also be caused by the wrong combination of hormone therapy. See Treatment Options.

Fibroids and Polyps

Fibroids and polyps are abnormal growths or tumors inside the uterus. These may be removed if they are causing uncomfortable symptoms.

Infections

Infections of the uterus or cervix can be serious and cause symptoms including excessive bleeding. Infections are commonly treated with antibiotics.

Bleeding Disorders

Disorders that impair blood clotting (thickening of the blood to slow or stop its flow) are serious disorders that need medical attention. If you think you have this disorder, it is important to see your doctor as soon as possible.

Higher risk candidates for heavy periods include

• Women who are overweight
• Women who have hormonal imbalances
• Women who have never been pregnant
• Women with thyroid problems or diabetes
• Women over 35

To determine the cause of your heavy periods, talk to your doctor.

The Doctor Discussion Guide can also help you talk with your doctor about your menstrual problem.
