ASMBS updated position statement on bariatric surgery in class I obesity (BMI 30–35 kg/m2)

Preamble The American Society for Metabolic and Bariatric Surgery (ASMBS) issued a position statement on the role of bariatric surgery in class I obesity in 2012 [1]. That statement was developed in response to inquiries made to the ASMBS by society members, physicians, patients, hospitals, health insurance payers, policy makers, and the media regarding the safety and efficacy of bariatric surgery for patients with body mass index (BMI) 30-35 kg/m 2 . In the evolving field of bariatric and metabolic surgery, The Clinical Issues Committee of ASMBS recognized the necessity to update the position statement since additional high quality data has emerged in the past 5 years to support bariatric surgery in class I obesity. In this updated statement, the ASMBS recommendations are presented that are derived from available knowledge, peer-reviewed scientific literature, and expert opinion. The statement may be revised in the future should additional evidence become available. The statement is not intended as, and should not be construed as, stating or establishing a local, regional, or national standard of care.
