The incretin effect describes how eating food causes a stronger insulin response than receiving the same amount of sugar directly into the bloodstream. In people with type 2 diabetes, this effect is reduced, but treatments like GLP-1 receptor agonists (injected) and DPP-4 inhibitors (taken by mouth) have been developed to help manage blood sugar. These therapies are considered promising for treating type 2 diabetes, and some studies suggest they may also benefit heart function.

Abstract

The term incretin effect was used to describe the fact that oral glucose load produces a greater insulin response than that of an isoglycemic intravenous glucose infusion. This difference has been attributed to gastrointestinal peptides GLP-1 and GIP. Since incretin effect is reduced in subjects with type 2 diabetes, despite GLP-1 activity preservation, two forms of incretin-based treatment have emerged: GLP-1R agonists, administered subcutaneously and DPP-4 inhibitors, administered orally. There is a great interest whether incretin-based treatment will be associated with sustained long-term control and improvement in β-cell function. The observation that GLP-1R agonists improve myocardial function and survival of cardiomyocytes highlights the need for further studies. Incretin-based therapies offer a new option and show great promise for the treatment of type 2 diabetes.
