(重定向自Bowel bypass syndrome)


Bowel-associated dermatosis–arthritis syndrome (BADAS), also called bowel bypass syndrome and intestinal bypass arthritis–dermatitis syndrome, 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.
