OBJECTIVE: To evaluate early changes in glycemia, insulin physiology and gut hormone responses to an easily tolerated and slowly ingested solid, low-carbohydrate mixed meal test (MMT) following laparoscopic adjustable gastric banding (LAGB) or Roux-en-Y gastric bypass (RYGB) surgery.SUBJECTS/METHODS: This was a prospective non-randomized study. Plasma glucose, insulin and c-peptide (to estimate hepatic insulin extraction; % HIE), incretins (GIP, aGLP-1) and pancreatic polypeptide (PP) responses to the MMT were measured at 4-8 weeks before and after surgery in obese, metabolically healthy patients (RYGB = 10F or LAGB = 7F/1M). Supplementary clamp data on basal endogenous glucose production (EGP) and peripheral insulin action (Rd = rate of glucose disposal) and metabolic clearance rates of insulin (MCR-INS) were available in five of the RYGB patients. Repeated measures were appropriately accounted for in the analyses.RESULTS: Following LAGB surgery, C-peptide and insulin MMT profiles (P = 0.004 and P = 0.0005, respectively) were lower with no change in % HIE (P = 0.98). In contrast, in RYGB subjects, both fasting glucose and insulin (triangle =-0.66 mmol l(-1), P
