摘要: Hyperinsulinemic hypoglycemia with severe neuroglycopenia has been identified as a late complication of Roux-en-Y gastric bypass (RYGB) in small number patients. The rapid resolution type 2 diabetes mellitus after RYGB is probably related to increased secretion the incretin hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), patients post-RYGB demonstrate prolonged elevations GIP GLP-1 compared non-hypoglycemic Nesidioblastosis some likely due trophic effects on pancreatic islets. Treatment should begin strict dietary (low carbohydrate) alteration may require trial diazoxide, octreotide, or calcium-channel antagonists, among other drugs. Surgical therapy include consideration restrictive form bariatric procedure, without reconstitution gastrointestinal continuity. Partial total resection be avoided.
