Bariatric surgery is the most effective intervention available for treating obesity and its numerous associated comorbid conditions,1,2 and for improving the quality and length of life for patients with severe obesity.3 Given the initial cost and risk of bariatric operations, defining the long-term benefits of bariatric surgery is critical for justifying its utility as an obesity treatment. Inadequate follow-up and lack of standardization of how to define failure of bariatric operations have limited the ability to fully assess their clinical utility. In this issue of JAMA, King et al4 provide recommendations for how to best measure clinically important weight regain after bariatric surgery based on Longitudinal Assessment of Bariatric Surgery (LABS) study outcomes.
