What is endometriosis?
Endometriosis is a chronic condition where tissue that is similar to the lining of the uterus grows in places outside of the uterus.
It’s a common condition that affects up to 1 in 10 people in New Zealand. The cause of endometriosis is not fully understood. It’s believed there is a strong genetic component, and that it can run in families. Those who have an immediate relative (mother or sister) with endometriosis are seven times more likely to develop endometriosis than those who do not.
The most common symptom of endometriosis is pelvic pain, usually during periods.
For some people, the symptoms of endometriosis are severe. Others may have no symptoms at all, although this is less common. Symptoms include:
1. Painful periods (dysmenorrhoea)
2. Bowel problems (diarrhoea, bloating, constipation, painful wind, painful bowel movements)
3. Pain during s*x (dyspareunia)
4. Infertility (inability to conceive) or sub-fertility (delayed conceiving)
5. Fatigue, tiredness, or low energy
6. Pain in other places, such as the lower back
7. Pain at other points in the menstrual cycle (often with ovulation)
8. Premenstrual syndrome (PMS)
9. Abnormal menstrual bleeding, including very heavy periods
10. Bladder issues (pain before/with urinating, recurrent urinary tract infections, interstitial cystitis).
If you notice any of these symptoms, book an appointment with a GP or Nurse Practitioner.
