Clinical Improvement After Duodenojejunal Bypass for Nonobese Type 2 Diabetes Despite Minimal Improvement in Glycemic Homeostasis

Background Glycemic control of type 2 diabetes mellitus (T2DM) remains a dilemma to physicians. Although gastric bypass surgery undertaken for morbid obesity has been shown to resolve this disease well, data on the effectiveness of duodenojejunal bypass in improving or resolving T2DM and the metabolic syndrome (MS), especially in nonobese patients are scarce.
