Bowel Bypass Syndrome: Gastrointestinal Features

  • Michael Tadros


Bowel bypass syndrome is seen in those with chronic diarrhea and malabsorption following a bypass procedure, biliary diversion, or other gastrointestinal (GI) disorders.

GI symptoms include:

Abdominal pain


Rectal bleeding

Stool incontinence

Clinical signs and findings can include:

Occurrence within weeks and up to 6 years after bowel bypass surgery

Usually acute and can be recurrent

Fever and chills may precede its onset

Malabsorption and fat-soluble vitamin deficiency, especially zinc deficiency

Endoscopy can reveal the area of gastrojejunal anastomosis from previous bypass surgery; this also can be confirmed by a barium study of the upper GI tract; inspection of the colon by colonoscopy may reveal evidence of colitis.
