Understanding Uterine Bleeding

Heavy or irregular bleeding between periods can happen for different reasons. Hormonal imbalance and uterine growths are two of the most common problems. Your health care provider can diagnose your problem and provide treatment that will relieve your uterine bleeding.

Hormonal Imbalances

Your menstrual cycle is controlled by hormones, including estrogen and progesterone. These same hormones can cause heavy periods or bleeding between periods when they are out of balance. Causes of hormonal imbalances 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 Uterine Growths

Fibroids are round "knots" of uterine muscle tissue.

Polyps are made of soft uterine lining tissue. They often hang into the uterus.

With adenomyosis the uterine lining cells grow into the muscle wall.

Hyperplasia is an overgrowth of the uterine lining.

Endometrial cancer is an uncontrolled growth of part of the uterine lining.
