Following nutrient intake, incretin hormones (glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1)) enhance glucose .The second incretin, GLP-1, was described.1 INTRODUCTION. Obesity is a risk factor for sleep apnea, said Saadia A. New evidence suggests that incretin hormones, particularly GLP-1, play a role in the pathophysiology of hyperinsulinemic hypoglycemia. Within the gut, it also acts to inhibit .GIP and GLP-1, originally characterized as incretin hormones, have additional effects in adipose cells, bone, and the cardiovascular system. Preclinical studies have demonstrated that GLP-1 .The incretin effect, the amplification of insulin secretion occurring when glucose is taken in orally as compared to infused intravenously, is one of the factors that help the body to tolerate carbohydrate/glucose ingestion. Journal of Hepatology.GLP-1 and GIP integrate nutrient-derived signals to control food intake, energy absorption, and assimilation.

In addition, these agents cause a weight loss which, with the most successful compounds, may exceed 10% of body weight.Glucagon-like peptide-1 (GLP-1) and glucose dependent insulinotropic polypeptide (GIP) are the two main incretins and are secreted by enteroendocrine L- and K-cells, respectively.
