Bowel-associated dermatosis–arthritis syndrome
Bowel-associated dermatosis–arthritis syndrome (BADAS), is a complication of jejunoileal bypass surgery consisting of flu-like symptoms (fever, malaise), multiple painful joints (polyarthralgia), muscle aches (myalgia) and skin changes. It has been reported to occur in up to 20% of patients who had jejunoileal bypass surgery, a form of obesity surgery that is rarely performed today.

An excessive immune response to gut bacteria is thought to cause BADAS. Antibiotics have been used successfully to treat the condition (including tetracyclines, macrolides, metronidazole and fluoroquinolones). Corticosteroids are an alternative. Surgical repair of the normal bowel transit, where possible, can be effective.
BADAS has later been reported in patients with inflammatory bowel disease, diverticulitis and following resection of the stomach (gastrectomy). BADAS has also been reported following biliopancreatic diversion (a form of bariatric surgery, also known as Scopinaro procedure), and in one case, BADAS occurred in a patient with acute appendicitis. Since "bowel bypass syndrome" is not applicable to these cases, the term BADAS was coined by Jorizzo and co-authors in 1984.
