title: Dry Beriberi and Wernicke's encephalopathy following gastric lap band surgery.
abstract: The incidence of neurologic complications from bariatric surgery is rising with the prevalence of obesity and the increasing number of bariatric surgeries. We report a 25-year-old woman who developed subacute progressive weakness and areflexia followed by confusion, ophthalmoplegia, and nystagmus following bariatric surgery. While the differential of generalized weakness with altered mental status is broad, vitamin deficiency should be routinely suspected after bariatric surgery to prevent permanent neurological injury. Multifocal neurological dysfunction in our patient represented beriberi and Wernicke's encephalopathy related to vitamin B1 deficiency.
