Overview

Endometrial tissue that becomes thick and grows into the uterine wall is a disorder called adenomyosis. This tissue continues to grow over the course of the menstrual cycle, which causes painful, heavy periods. The condition can turn into adenomyoma, which is a growth inside of the uterus. Serious pain and unusual bleeding can make everyday activities difficult.

The cause of adenomyosis is unknown. Researchers believe adenomyosis may occur due to cuts made during C-section operations, inflammation from giving birth or abnormal estrogen production. Sometimes adenomyosis doesn’t cause any symptoms or is only a little uncomfortable, but other times it can be very painful.

Adenomyosis usually affects women older than 30 years who have had children, and patients who have had uterine surgery, such as a C-section or removal of fibroids. The disease typically goes away after menopause.
