What is Endometriosis?

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus, most commonly on the ovaries, fallopian tubes, or pelvic lining. This tissue responds to the menstrual cycle in the same way as the uterine lining, causing inflammation, pain, and sometimes the formation of scar tissue.

It commonly causes painful periods, pelvic pain, pain during sex, and sometimes fertility difficulties, though severity doesn't always match how much tissue is present. It's a real, recognised medical condition — not something to be dismissed as "just bad periods" — and effective treatments exist to manage symptoms.
