The rapid effects of sleeve gastrectomy on glucose homeostasis and resolution of diabetes mellitus

Aims Type 2 diabetes caused by obesity is increasing globally. Bariatric surgical procedures are known to have positive effects on glucose homeostasis through neurohormonal action mechanisms. In the present study, we aimed to investigate the factors influencing glucose homeostasis independent of weight loss after the laparoscopic sleeve gastrectomy (LSG). Methods Patients who underwent LSG for morbid obesity in a 3‐year period were evaluated. Data on demographics, clinical characteristics (duration of diabetes, resected gastric volume, antral resection margin) and laboratory parameters (preoperative and postoperative blood glucose on fasting, preoperative HbA1c levels and first‐year HbA1c levels) were retrospectively reviewed. Effect of patients' body mass index (
