In a study of more than 30 000 adults in France published in this issue of JAMA Surgery, Thereaux et al1 observed that bariatric surgery was associated with a significantly higher antidiabetic treatment discontinuation rate 6 years after surgery (50%) compared with the discontinuation rate in a control group of patients with obesity (9%), with gastric bypass being the most effective procedure. Beyond the usual and obvious dangers of interpreting data from an administrative database, this analysis lacks a defined criteria for type 2 diabetes and weight loss; however, it confirms other analyses, such as those resulting from the Swedish Obesity Study.2
