International Consensus Guides Obesity Management: IFSO Delphi Study

In a Delphi survey involving 43 global obesity experts, unanimous consensus (≥70% agreement) was achieved on 15 essential definitions and reporting standards in metabolic bariatric surgery (MBS). Notable agreement (95/121 statements) covered preferred surgical procedures like Roux-en-Y gastric bypass and sleeve gastrectomy. Moderate consensus existed for specific procedures, but none for intra-gastric balloons. Agreement extended to MBS in patients >65 and <18 years old with BMI >50 kg/m². This study establishes vital guidelines for obesity management endorsed by a multidisciplinary expert panel.
