Where does endometriosis appear?

The pelvis area or the lower abdomen is the most frequent place for endometriosis. The female reproductive organs, the rectum, the bowels, and the bladder are inside the pelvis. They can be affected in various degrees by endometriosis. Its name derives from the endometrium - the name of the lining of the uterus (the womb), which suffers an abnormal growth outside its normal place.

Even if is not a malignant or life-threatening disease, endometriosis is a serious matter for many women. If left untreated, it threatens to affect reproductive health and the quality of life. Most women who fear the risk of endometriosis may wonder where it appears more often.

Endometriosis seems to be found mostly on the pelvic peritoneum - the membrane that lines the peritoneum and helps the organs inside the pelvis to slide inside the abdominal cavity. The appearance of endometriosis patches causes organs to join each other as they are sticky usually causing pain.

The usual places for endometriosis patches are behind the vagina and uterus, underneath the ovaries, sometimes inside the ovaries. It can also be found in front of the uterus, between the uterus and the bladder, while the related disease - adenomyosis - occurs inside the wall of the uterus. Endometriosis may sometimes occur on the Fallopian tubes, disrupting their role. It is less common to appear on the vagina, the cervix, the bladder.

Rarely, endometriosis has been reported outside the pelvis

It may occur in other parts of the abdominal cavity - e.g. the surface of the liver, the lung tissue, the abdominal wounds – old cesarean or other surgical scars, or the brain.

Endometriosis has four different stages, from mild to severe. The larger the patches, usually the worse are the symptoms - pain during period, pain during sex, etc.  For some women, the symptoms can go unnoticed, and sometimes they can even disappear without treatment. The diagnosis can only be confirmed by a doctor. A pelvic exam or laparoscopy should be performed before making any decision about the right treatment.
