Obesity is a chronic disease that may require multiple interventions and escalation of therapy throughout the years. Until recently, no universal definition existed for recurrent weight gain and insufficient weight loss. Standardization of reporting is key so outcomes can be compared and data can be pooled. The recent IFSO consensus provided standard terminology and definitions that will likely resolve this in the future, and publishers will need to enforce for authors to use these definitions. This current IFSO position statement provides guidance for the management of recurrent weight gain after bariatric surgery.
