1) A randomized controlled trial compared gastric bypass (GB) and sleeve gastrectomy (SG) for treating type 2 diabetes mellitus (T2DM) in 60 moderately obese patients.
2) At 12 months, remission of T2DM was achieved by 93% in the GB group and 47% in the SG group, indicating GB was more effective at treating T2DM.
3) Participants who received GB had greater weight loss and better control of glucose, HbA1c, and blood lipid levels compared to those who received SG. No serious complications occurred in either group.
