Excessive Menstrual Bleeding

Excessive menstrual bleeding can happen for different reasons. Hormonal imbalance and menstrual growths are two of the most common causes.

Hormonal Imbalances

Your menstrual cycle is controlled by hormones, including estrogen and progesterone. When they are out of balance, these same hormones can cause heavy periods or bleeding between periods. Causes of hormonal imbalances may include:

  • Hormonal changes in teens and women nearing menopause
  • Diabetes, thyroid disease or other medical problems
  • Obesity
  • Stress
  • Strenuous exercise
  • Anorexia (an eating disorder)

Types of Menstrual Growths:

  • Fibroids are round “knots” of menstrual muscle tissue.
  • Polyps are small growths of tissue from the menstrual lining that grow inside, and often hang into the uterus.
  • Adenomyosis occurs when cells of the menstrual lining grow into the muscle wall.
  • Hyperplasia is an overgrowth of the menstrual lining.
  • Endometrial cancer is an uncontrolled growth of cells of the menstrual lining in the abdomen

Treatments for Excessive Menstrual Bleeding

Excessive menstrual bleeding can be treated with hormone therapy, surgery or a combination of both. Your health care provider can diagnose your condition and provide treatment(s) to relieve your symptoms.
