What Is Endometriosis?

Endometriosis occurs when tissue similar to the uterine lining (endometrium) grows outside the uterus — on the ovaries, fallopian tubes, bowel, bladder or peritoneum. Like the uterine lining, it bleeds during periods but the blood has nowhere to escape, causing pain, inflammation and scar tissue.

Symptoms

Diagnostic Tests

TestRole
CA-125 blood testElevated in many women with endometriosis but not specific or sensitive enough for diagnosis alone
Pelvic ultrasoundCan detect endometriomas (chocolate cysts on ovaries)
MRI pelvisBest non-surgical imaging for deep infiltrating endometriosis
LaparoscopyGold standard — surgical visualisation and biopsy confirms diagnosis

Treatment

FAQs

Why does endometriosis take so long to diagnose?
Symptoms are often dismissed as 'bad periods'. Definitive diagnosis requires laparoscopy. Increased awareness is helping reduce diagnostic delays.
Does endometriosis always cause infertility?
No — many women with endometriosis conceive naturally. Severe cases or those affecting the tubes/ovaries have higher infertility risk.
Does menopause cure endometriosis?
Menopause usually causes lesions to regress, but endometriosis can persist in some women — especially on HRT.
Medical Disclaimer: Endometriosis should be managed by a gynaecologist with specialist experience. Do not accept being told 'painful periods are normal' — seek further investigation.
