About Endometriosis

According to the National Institutes of Health, endometriosis occurs when tissues that usually grow inside the uterus instead grow on the outside. These tissues often grow on the surfaces of organs in the pelvis or abdomen, where they are not supposed to grow.

Endometriosis is one of the most common gynecological diseases, affecting more than 5.5 million women in North America. An estimated 2 to 10 percent of women of reproductive age have endometriosis. Additional information can be found at http://www.nichd.nih.gov/health/topics/endometriosis.cfm.
