There is evidence about the benefits of bariatric surgery including rapid weight loss and improvements in comorbidities; however, not much is known about its negative health consequences. This article investigates the prevalence of micronutrient deficiencies pre- and postoperatively in adults who have undergone a sleeve gastrectomy. The accompanying case report describes a patient with morbid obesity who developed Wernicke's encephalopathy due to complications after bariatric surgery. Also, it highlights the patient's care as well as missed opportunities to diagnose a micronutrient deficiency. © 2021 Wolters Kluwer Health, Inc. All rights reserved.
