Abstract
Background
Obesity is intricately associated with type-2 diabetes (T2D) and other cardiovascular conditions, increasing morbidity, mortality, and health care costs. Metabolic and bariatric surgeries (MBS) have shown promising results in significant weight loss and T2D remission, but existing predictive scores for post-MBS diabetes remission do not consider insulin dosage, potentially overlooking a critical factor.
Methods
A retrospective analysis of patients with T2D who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). The study focused on insulin dosage impact, divided into quartiles, on remission rates post-MBS. The effectiveness of RYGB vs SG was compared within insulin dose quartiles with up to 5 years of follow up.
Results
A total of 508 patients (64% female, 94.9% White, mean age 53.5 ± 10.5 years, BMI (46.0 ± 8.3 kg/m2) were included in the analysis. This study demonstrates a profound association between insulin dosage quartiles and T2D remission after MBS. Patients with lower insulin requirements showed superior remission rates; those in the lowest quartile had remission rates of 73%, 70%, and 62% at 1, 3, and 5 years, respectively, compared to 34%, 37%, and 36% in the highest quartile (P < 0.001 across all intervals). RYGB surgery showed a significantly better remission in the second and third insulin quartiles, suggesting its effectiveness over SG for patients with mid-range insulin requirements.
Conclusion
This study underscores the importance of considering insulin dosage when predicting T2D remission post-MBS. The findings advocate for a more nuanced selection of MBS procedures based on individual insulin profiles, potentially enhancing diabetes remission outcomes.
