1827-P: Higher Glucagon-Like Peptide-1 Response and Lower Beta-Cell Glucose Sensitivity Are Associated with Increased Glycemic Variability among Individuals with Prediabetes

Background: Increased glycemic variability (GV) is thought to represent abnormalities of glucose homeostasis in the progression from prediabetes to diabetes. We evaluated the association between GV, beta-cell function and glucagon-like peptide 1 (GLP-1) response among individuals with prediabetes. Methods: 61 individuals with prediabetes (age Mean±SD 56±9 years, 31 male) each wore a blinded continuous glucose monitor (Medtronic iPro2) for 72...
