OBJECTIVE: To report the impact of bariatric surgery on metabolic outcomes in patients with type 1 diabetes (DM1) versus insulin-requiring type 2 diabetes mellitus (IRDM2). METHODS: Ten subjects with DM1 were compared with 118 subjects with IRDM2 at baseline and at 1 and 2 years post-bariatric surgery for: anthropometric measures, HbA1c, and number of medications (anti-hyperglycemic, anti-hypertensive, lipid-lowering). RESULTS: DM1 and IRDM2 groups lost similar amounts of weight 2 years post-bariatric surgery (39.5 ± 14.7 kg vs. 40.3 ± 24.4 kg). IRDM2 subjects had significant improvements in HbA1c (7.8% ± 1.4% vs. 6.8% ± 1.4%, P value <0.0001) and decreases in number of anti-hyperglycemic (2.4 ± 0.8 vs. 0.7 ± 0.8, P value <0.0001), anti-hypertensive (2.2 ± 1.3 vs. 1.3 ± 1.2, P value <0.0001), and lipid-lowering (1.1 ± 0.8 vs. 0.6 ± 0.6, P value <0.0001) medications. DM1 subjects had no improvement in HbA1c (8.2% ± 1.6% vs. 7.8% ± 0.9%) or use of anti-hypertensive medications (2.1 ± 1.4 vs. 2.3 ± 1.5). Their use of lipid-lowering medications improved (1.0 ± 0.5 vs. 0.5 ± 0.8, P value 0.04). CONCLUSIONS: Our study suggests that improved glycemic control may not be an expected outcome when considering bariatric surgery in patients with DM1; however, additional investigation is warranted.
