Endometriosis
Endometriosis
Endometriosis is a reproductive problem that affects millions of women and girls around the world.1,2 It causes painful, life-impacting symptoms and may affect work and school attendance.1,2
What is Endometriosis?
Endometriosis occurs when endometrial tissue, the tissue that normally lines the inside of the uterus, grows outside the uterus.1,3 When it grows in places it should not normally be, most commonly on the ovaries and the pelvic peritoneum1 (the membrane that lines the inside of the abdomen and pelvis),4 inflammation and scar tissue develop in the pelvic area.2
Endometriosis is illustrated below:

Endometriosis Causes and Risk Factors
- Genetics (passed down by family members with the same condition).5
- Immune system problems.5
- Lymph system abnormalities that may cause the development and spread of endometrium cells.5
Endometriosis Symptoms
- Painful periods.
- An irregular menstrual cycle (not having a period regularly each month).
- Pelvic pain.
- Pain during sex.
- Infertility.
- Nodules (lumps) on the ligaments of the uterus, which can be felt during a physical examination.
- Masses or cysts on the ovaries, which can be felt during a physical examination.
- A uterus that is ‘tipped backwards’ (retroverted).
Did You Know? There is not enough data on how many people in a community of African women suffer from endometriosis. More locally focussed research into this difficult condition is needed.6
Diagnosing Endometriosis
- A physical (pelvic and vaginal) examination by a general practitioner (GP).
- An ultrasound scan or MRI done by a healthcare professional or other specialist.
- A laparoscopy done by a surgeon – keyhole surgery where a tiny camera is used to look for patches of endometriosis tissue.
Impact of Endometriosis
Treatment of Endometriosis
- Non-steroidal anti-inflammatory drugs (NSAIDs) or oral contraceptive pills can be used to manage pelvic pain and regulate periods.1
- Hormonal therapies, like progestogens and antiprogestins, or gonadotropin-releasing hormone (GnRH) analogues may also be used.1
- Severe cases may require surgery, either to cut away the endometriosis tissue or to remove the uterus (a hysterectomy).1
