Background. We investigated the effect of laparoscopic sleeve gastrectomy (LSG) on morbidly obese diabetics and examined the short-term impact of LSG on diabetic medication cost. Methods. A prospective database of consecutive bariatric patients was reviewed. Morbidly obese patients with type 2 diabetes who underwent LSG were included in the study. Age, gender, body mass index (BMI), diabetic medication use, glucose, insulin, and HbA1c levels were documented preoperatively, and at 2 weeks, 2 months, 6 months, and 12 months postoperatively. Insulin resistance was estimated using the homeostatic model assessment (HOMA). Use and cost of diabetic medications were followed. Results. Of 178 patients, 22 were diabetics who underwent LSG. Diabetes remission was observed in 62% of patients within 2 months and in 75% of patients within 12 months. HOMA-IR improved after only two weeks following surgery (16.5 versus 6.6, 𝑃 < 0 . 0 0 1 ). Average number of diabetic medications decreased from 2.2 to <1, within 2 weeks after surgery; corresponding to a diabetes medication cost savings of 80%, 91%, 99%, and 99.7% after 2 weeks, 2 months, 6 months, and 12 months, respectively. Conclusion. Morbidly obese patients with diabetes who undergo LSG have high rates of diabetes remission early after surgery. This translates to a significant medication cost savings.
