Diabetes Mellitus Remission in Patients with BMI > 50 kg/m 2 after Bariatric Surgeries: A Real-World Multi-Centered Study.

Introduction: Type 2 diabetes mellitus (T2DM) is a common comorbidity associated with obesity, particularly in patients with body mass index (BMI) ≥ 50 kg/m ² . We aim to study real-world T2DM long-term remission in patients with BMI ≥ 50 kg/m ² following Roux-En-Y gastric bypass (RYGB) or sleeve gastrectomy (SG).
Methods: This was a retrospective study of the electronic medical records of all patients with BMI ≥ 50 kg/m ² , T2DM, and have undergone RYGB or SG at three tertiary referral centers in the United States. We assessed the change in T2DM outcomes after bariatric surgery using a matched paired t-test for continuous variables and Bowker and Pearson test for categorical variables. We performed a multivariate logistic regression to determine predictors of remission.
Results: A total of 279 patients with T2DM (65% females, mean age 51.0 ± 11.7 years, 89% white, BMI 56.6 ± 5.9 kg/m ² ) were analyzed. Long-term T2DM remission (≥ 5 years) was demonstrated in 47% of patients. The duration of T2DM (p < 0.0001), number of T2DM medications (p = 0.003) and weight loss (p = 0.048) were the only independent factors for long-term T2DM remission.
Conclusions: In this cohort of patients with BMI ≥ 50 kg/m ² , RYGB and SG demonstrated significant and similar long-term T2DM remission rates and weight loss outcomes.
