Effects of gastric banding on glucose tolerance, cardiovascular and renal function, and diabetic complications: a 13-year study of the morbidly obese

Despite a very small weight loss over the long term (i.e., 2.2 kg/m2), improvement of glucose tolerance persisted for long periods after LAGB, with no unfavorable effect on kidney function and retinopathy. In contrast, no effect was observed on prevention of arterial hypertension or cardiovascular disease.
