Endometriosis occurs when tissue similar to the lining of the uterus (endometrium), is found in places outside of the uterus. The tissue can form nodules or plaques which may be visualised at surgery. Endometriosis is commonly found in the pelvic region on the thin pelvic lining called the peritoneum. It may be also be found on the pelvic ligaments, ovaries and bowel. Endometriosis is occasionally found in places outside the pelvis such as in scar tissue, the bellybutton or lungs.
Often if you see your doctor with concern about your periods they will order an ultrasound scan. This can not diagnose most forms of endometriosis, but it can pick up cysts on the ovaries (endometrioma).
Endometriosis is commonly associated with adhesions, which can make surgery more challenging.
If there is endometrial tissue in the muscle of the uterus we call it adenomyosis in the pelvic cavity.
What are the stages?
Mild or Stage II endometriosis: more extensive than stage I but infiltration of pelvic organs still very limited, without a great deal of scarring or adhesions.
Moderate or Stage III endometriosis: sometimes more widespread and starting to infiltrate pelvic organs, peritoneum (pelvic side walls) or other structures. Sometimes there is also scarring and adhesions.
Severe or Stage IV endometriosis: infiltrative and affecting many pelvic organs and ovaries, often with distortion of the anatomy and adhesions.
It's important to know that the stage of endometriosis doesn't always correlate with the level of pain or other symptoms a person experiences. Someone with Stage I endometriosis could have debilitating pain, while another with Stage IV may have minimal symptoms. This is because pain is influenced by where the tissue is located, not just how much of it there is. The condition can lead to a range of symptoms, including severe pain, fatigue and infertility.
