Automated summary

Major updates to the 1991 National Institutes of Health guidelines for bariatric surgery recommend metabolic and bariatric surgery (MBS) for individuals with a body mass index (BMI) >35 kg/m2 regardless of co-morbidities. It is also suggested that individuals with metabolic disease and a BMI of 30-34.9 kg/m2 should consider MBS. Furthermore, BMI thresholds should be adjusted for the Asian population, with a BMI >25 kg/m2 indicating clinical obesity, and MBS offered to individuals with a BMI >27.5 kg/m2. The long-term safety and efficacy of MBS have been consistently demonstrated, and selected children and adolescents may also be considered for MBS.
