Bowel bypass syndrome is also known as bowel-associated dermatitis-arthritis syndrome and blind loop syndrome.
Bowel bypass syndrome is a relapsing condition characterized by rash and arthritis. It is most commonly associated with bowel shortening surgery, where a ‘blind loop’ of bowel is created. This kind of surgery was previously popular for the treatment of morbid obesity. Up to 20% of patients undergoing bowel bypass surgery develop bowel bypass syndrome.
A similar syndrome has been reported in people who have not had bowel bypass surgery (‘bowel bypass syndrome without bowel bypass’). In these cases associated conditions have included:
Bowel bypass syndrome is thought to be caused by bacterial overgrowth in a blind loop of bowel. A blind loop is a length of small intestine which digested food does not pass through. The effect is shortening of the small intestine, which leads to reduced absorption of fats and subsequent weight loss.
Bacterial overgrowth in the blind loop leads to release of bacterial antigens into the circulation. These antigens are called peptidoglycans. Peptidoglycans bind with circulating antibodies and these antibody-antigen complexes are deposited into skin and joints causing inflammation.
Bacteria identified as having a causative role in bowel bypass syndrome include:
