What is adenomyosis?

Adenomyosis is a thickening of the uterus. The condition occurs when endometrial tissue moves into the uterus’ outer muscular walls. Normally, endometrial tissue lines the uterus. Adenomyosis may result in an adenomyoma, which is a mass or growth inside the uterus. Some form of the condition may affect 60% of women.

What causes adenomyosis?

The condition’s cause is not known, but it usually occurs in women over the age of 30. Adenomyosis rarely is found in women who have not carried a pregnancy to term.

What are the symptoms of adenomyosis?

In many cases, there are no symptoms for the condition. Symptoms that may occur include:

  • Painful menstruation that may involve new cramping that becomes increasingly worse.
  • Heavy or prolonged menstrual bleeding.
  • A uterus that is 2-3 times its normal size.
