Endometriosis is a common gynaecological condition, affecting up to 1 in 10 women. Endometriosis is when the tissue that forms the lining of your uterus grows outside of your uterine cavity. This uterine lining (endometrium) can grow on your ovaries, bowel, and membranes lining your pelvis.
The hormonal changes in the menstrual cycle impact this misplaced tissue, causing the pelvic area to become inflamed and painful. The tissue will continue to grow, thicken, and then break down. Over time, the broken down tissue has nowhere to go and becomes trapped in your pelvis.
This trapped tissue can cause- irritation, scar formation, adhesions, in which tissue binds your pelvic organs together, severe pain during your periods and fertility problems.
Endometriosis has 3 stages or types. It can be any of the following: mild, moderate and severe.
