Wernicke encephalopathy, which is caused by a thiamine deficiency, occurs in 0.8-2% of the population. Only 16% present the typical triad of this disease: nystagmus, confusion and ataxia. We present the case of a postoperative patient with a one anastomosis gastric bypass with reoperation undergoing a Roux-en-Y gastric bypass that begins with confusion and nystagmus on her third postoperative day. The diagnosis of Wernicke encephalopathy is made by imaging, and vitamin B1 is administered with total improvement of nystagmus and altered state of consciousness (lethargy, bradypsychia, bradylalia).

Palabras llave : Wernicke encephalopathy; Bariatric surgery; Vitamin B1 deficiency.
