2108-P: Model-Based Assessments of Glucose Metabolism in Morbid Obese (MO) Subjects Before and After Bariatric Surgery (BS)

Improvement of insulin resistance (IR) as contributor of diabetes remission and prevention is a well known beneficial effect of BS. We investigated the changes in IR and sensitivity (IS) in MO patients with newly diagnosed type 2 diabetes (DM) before and 2 years after BS and compared the changes to patients with either impaired fasting glucose or impaired glucose tolerance (IGT/IFG). We included 27 patients with DM (mean age 44±12 years, mean±SD, BMI 49± 10kg/m²) and 104 patients with IGT/IFG (mean age 41±11 years, BMI 47± 7kg/m²). All patients had a 75g oGTT, glucose and insulin levels were repeatedly measured for calculation of IR and IS indices (Table). BMI (p= 0.742) and age (p= 0.194) were not different between both groups. Indices are shown in the Table. Before BS, IR was significantly higher in DM for all indices (p Disclosure J. Brix: None. E.
