Sleeve Gastrectomy (SG) is associated with higher T2DM relapse rates and less sustained glycemic control compared to Roux-en-Y Gastric Bypass (RYGB) over a 5-year period.
If you have already had Sleeve Gastrectomy (SG) and achieved diabetes remission, be aware that the risk of diabetes returning (relapse) is higher compared to those who had Gastric Bypass (RYGB). Regular monitoring of your blood sugar is crucial, as SG may not sustain remission as effectively as RYGB in the long term.
GoodSupportsHIGH confidence
Among 6141 patients who experienced T2DM remission, the subsequent T2DM relapse rate was lower for those who had RYGB than those who had SG (hazard ratio, 0.75 [95% CI, 0.67-0.84]).
Why this rating
Large cohort study with robust statistical modeling for relapse.

- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
