Bowel bypass dermatitis

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). [Source: Wikipedia ]
