Abstract

Background: The prevalence of obesity among children and adolescents is rising and poses a major health concern. Bariatric surgery is well established in adults and has become an option for adolescents. Thiamine (B1) deficiency is common following bariatric surgery in adults. It may present as Beri-Beri, Wernicke encephalopathy, or Korsakoff psychosis. Objective: Our aim was to describe the clinical features, diagnosis, and treatment of adolescents who presented with B1 deficiency after bariatric surgery at one center, and to summarize the data from the literature. Patients: Three adolescents with morbid obesity (two boys and one girl, aged 15.5 to- 17-years-old), presented at Schneider Children's Medical Center of Israel with progressive lower limb pain and weakness 2–3 month following a bariatric procedure (sleeve gastrectomy or narrowing of a bariatric band). The girl also had upper limb involvement and cerebellar signs. All three were non-compliant with micronutrient supplementation. After admission, they received intravenous B1 and oral multivitamin supplementation, and their symptoms improved considerably. Conclusions: Micronutrient supplementation following bariatric surgery is crucial to prevent deficiencies. In adolescents, compliance with micronutrient supplementation should be assessed before and after such surgery. Thiamine deficiency may cause polyneuropathy, among other symptoms. Treatment reduces the severity of neurological complications.
