What is endometriosis?
Endometriosis is a common gynaecological condition. Every month, the lining of the uterus (the endometrium) prepares to receive a pregnancy and is then shed with the period. In endometriosis, tissue similar to this lining is found outside the uterine cavity, for example on the ovaries, tubes, peritoneum or, more rarely, the bowel and bladder. This tissue responds to the hormones of the cycle and causes inflammation, pain and sometimes adhesions.
The exact cause is not fully known. It is not cancer, it is not contagious and it is not the result of lifestyle.
