What is Endometriosis

Endometriosis (pronounced en – doh – mee – tree – oh – sis) is a complex condition involving hormonal and immune systems. It is a common chronic (long-term) inflammatory condition.

Endometriosis can affect people of all backgrounds and ages, including teenagers.

Symptoms of Endometriosis

People experience a wide range of symptoms and present with various configurations of these which make endometriosis difficult to recognise and diagnose.

The most widely experienced symptoms are pelvic and period pain, painful intercourse, fertility problems, bowel issues, immunity issues, fatigue and, related mental health concerns, particularly low mood.

Our Endometriosis Information Guide has more information about symptoms and a checklist of symptoms that can help determine if endometriosis should be suspected and can be taken to a GP appointment to discuss symptoms.

Causes of Endometriosis

The cause of endometriosis is not well understood with many theories but no medical agreement. The endocrine (hormonal) and immune systems are thought to be involved.

There are four different types of endometriosis that may be caused in different ways and therefore may require different treatments.   

Diagnosing Endometriosis

The only definitive way to diagnose endometriosis is through laparoscopic (key-hole) surgery.


GP's may be able to offer a clinical (tentative) diagnosis based on symptoms.

It may take some time to get a diagnosis as the symptoms of endometriosis can be wide-ranging and are very similar to other common conditions.
