Clinical term

Endometriosis

Endometriosis is a chronic inflammatory disease in which tissue similar to the lining of the uterus grows outside the uterine cavity. It can cause severe pelvic pain and infertility.

Scientific basis

Endometriosis affects roughly one in ten women of reproductive age. Lesions are most often located in the pelvis: peritoneum, ovaries, uterosacral ligaments, sometimes the bowel or bladder.

The most common symptoms are very painful periods (dysmenorrhea), chronic pelvic pain, pain during intercourse, digestive or urinary pain, and fatigue. Pain intensity does not always reflect the extent of the lesions, and diagnosis is often delayed.

The disease involves several mechanisms: hormonal dependence on estrogens, inflammation, interactions between the immune system and nerves, and, in some people, sensitization of the nervous system. Treatments combine pain medication, hormonal therapy and, in some cases, surgery.

Blue Portance / SBNFA™ reading

SBNFA™ does not present endometriosis as a mechanical problem and claims neither to explain it nor to treat it. Its analysis is limited to the conditions of sitting, which can be difficult to tolerate for many of the people affected: pressure on the pelvis and perineum, how long the position is held, and the possibility of varying the points of support.

When scars or adhesions limit tissue gliding, the SBNFA™ reading focuses on what the seat still leaves possible in terms of adjustments, alongside medical care.

Contribution to the analysis of sitting

Observing how long sitting is tolerated, which support areas are painful and whether it is possible to change position provides functional information. It does not make it possible to assess the disease itself.

Not to be confused with

Adenomyosis, the presence of endometrial tissue in the muscle of the uterus; pudendal neuralgia, involvement of a nerve of the perineum; pelvic-perineal pain, a broader category that can have other origins.
