Abstract
The early improvement of glucose control taking place shortly after gastric bypass surgery in obese diabetic patients has long been mysterious. A recent study in mice has highlighted some specific mechanisms underlying this phenomenon. The specificity of gastric bypass in obese diabetic mice relates to major changes in the sensations of hunger and to rapid improvement of glucose parameters. The induction of intestinal gluconeogenesis plays a major role in diminishing hunger, and in restoring insulin sensitivity of endogenous glucose production. In parallel, the restoration of the secretion of glucagon-like peptide 1 and insulin plays a key additional role, in this context of recovered insulin sensitivity, to improve postprandial glucose tolerance. Therefore, a synergy between an incretin effect and intestinal gluconeogenesis is a key feature accounting for the rapid improvement of glucose control in obese diabetic patients after bypass surgery.

This is the first study addressing the question of IGNG shortly after gastric bypass surgery in humans. The experiments were performed 6 days after the operation, 8 hours after the last meal intake. Whereas the physiologic importance is difficult to evaluate from the parameters studied, a net release of glucose in the portal vein is reported in nondiabetic obese patients.
