title: Eating avoidance disorder and Wernicke-Korsakoff syndrome following gastric bypass: an under-diagnosed association.
abstract: Wernicke-Korsakoff syndrome (WKS) and disordered eating behavior have been reported separately after bariatric surgery. We report a patient who following a bariatric operation developed WKS associated with a disturbed eating behavior without vomiting. This morbidly obese man developed an intense fear of gaining weight in the postoperative period and engaged in an extreme form of "food avoidance behavior". 2 months postoperatively after severe weight loss, he was hospitalized with disorientation and an amnesic syndrome. He was discharged 2 months later with stable weight and regular eating habits. Despite this, at the last follow-up visit 2 years postoperatively, he still had a residual partial amnesic syndrome. The surgical team must be aware of peculiar forms of pathological eating that may appear after bariatric surgery; the emergence of an eating avoidance disorder may be associated with the development of WKS.
