Metabolic and bariatric surgery for adolescents with severe obesity: Benefits, risks, and specific considerations

Abstract

International and national guidelines recommend metabolic and bariatric surgery (MBS) as a treatment option for adolescents with severe obesity, but few countries offer MBS to adolescents in routine clinical care. This narrative review summarizes existing adolescent MBS guidelines and the available underpinning evidence. Two randomized trials and additional prospective studies have demonstrated efficacy and safety in adolescent MBS, and the health benefits appear to be similar or superior to outcomes in adults. However, there are specific challenges regarding the intervention during adolescence related to decision-making capacity and a peak in risk-taking behavior. Adolescents with severe obesity have—as a group—a mental health vulnerability, and specific nutritional concerns need to be addressed in relation to MBS. This review also describes how study findings can be translated into clinical care. We use Sweden as an example, where the National Board of Health and Welfare recommends MBS for selected adolescents with severe obesity aged 15 years or older. We present practical advice for implementing and integrating MBS in adolescents in the framework of multidisciplinary pediatric and adolescent care for obesity.
