title: The contribution of enteroinsular hormones to the pathogenesis of type 2 diabetes mellitus.
abstract: The gastrointestinal hormones glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), termed incretins, are essential regulators of normal glucose homeostasis. Research indicates that the incretin effect is impaired in type 2 diabetes, and this seems to be a consequence rather than a cause of type 2 diabetes. This review describes the defects in the incretin system seen in diabetic patients and discusses the potential roles of GIP and GLP-1 in the pathogenesis of type 2 diabetes. In addition, new information on clinical applications that exploit the enteroinsular axis to control blood glucose is discussed.
