What is endometriosis?

Endometriosis is a condition where the tissue similar to the lining of your uterus (the endometrium), grows in other areas within your pelvis. Common locations for endometriosis include around your ovaries, fallopian tubes, and outer surface of your uterus, but abnormal tissue growth can even be found around your bladder and bowel.

Like the normal endometrium inside your uterus, this tissue responds to your monthly hormonal cycle, thickening then breaking down during your menstrual period. However, as this blood has nowhere to go, it results in chronic inflammation, scarring, adhesions, and severe pain. Most women with endometriosis are diagnosed in their 20s or 30s, but even teenagers can be diagnosed with it, too.
