What is endometriosis?

Endometriosis occurs when the uterine lining migrates and adheres to extra-uterine places, causing inflammation and scarring. Women may or may not experience symptoms.

Endometriosis occurs when the endometrial lining, normally confined to the uterus, migrates and adheres to extra-uterine places, like the fallopian tubes, ovaries, or vagina. This misplaced tissue then continues to respond to hormonal changes, growing thicker throughout the cycle and bleeding during menstruation. The blood becomes trapped, causing congestion and inflammation in the affected area. Throughout time, this inflammation gives way to scarring and possible blockage of the fallopian tubes or ovaries.

Symptoms therefore depend on the location of the endometrial implant. Common symptoms include intense pain during menstruation, irregular bleeding in between periods, and pain during intercourse. Many women may not experience symptoms.
