Bariatric surgery ‐induced weight loss in patients with and without type 2 diabetes mellitus

SummarySurgical treatment of obesity leads to weight loss and metabolic improvement, but it is unclear if the response differs between patients with and without type 2 diabetes. Retrospective cohort study comparing weight loss and metabolic outcomes between patients with and without type 2 diabetes, matched for body mass index (BMI), gender and age, 12  months after Roux‐en‐Y gastric bypass. Forty‐eight patients with type 2 diabetes (D) and 48 without type 2 diabetes (ND) were evaluated, 87.5% female, mean age 42.2 ± 0.9 years. The mean baseline weight and BMI of the D and ND groups were, respectively, 120.3 ± 21.6 vs 123.7 ±  20.8 kg (P = .45) and 47.2  ± 7.5 vs 47.2 ± 6.9 kg/m2 (P = .70). After 12  months, there was no significant difference in weight (40.4 ± 16.9 vs 44.1 ± 12.2 kg,P = .28) and BMI (15.8  ± 6.5 vs 16.9 ± 4.5 kg/m2,P = .26) variation between groups. The parameters that presented significant variation were (D vs ND): fasting blood glucose (41.6  ± 43.0 vs 12.7 ± 17.2 mg/dL,P <  .01), HbA1c (1.8 ± 1.6 vs 0.6 ± 0.7%;P <  .01), triglycerides (91.1 ± 100.4 vs 54.2 ± 43.8 mg/dL;P = .04), low ‐density lipoprotein (27.2 ± 41.5 vs 37.5 ± 24.2 mg/dL;P <  .01) and gamma glutamyl transferase (46.5 ± 55.3 vs 17.7 ± 11.9 UI/L;P = .04). Weight loss 12  months after a gastric bypass was similar in patients with and without type 2 diabetes, ...
