- Abstract
- OBJECTIVE: To quantitate the separate impact of obesity and hyperglycemia on the incretin effect (i.e., the gain in beta-cell function after oral glucose versus intravenous glucose). RESEARCH DESIGN AND METHODS: Isoglycemic oral (75 g) and intravenous glucose administration was performed in 51 subjects (24 with normal glucose tolerance [NGT], 17 with impaired glucose tolerance [IGT], and 10 with type 2 diabetes) with a wide range of BMI (20-61 kg/m(2)). C-peptide deconvolution was used to reconstruct insulin secretion rates, and beta-cell glucose sensitivity (slope of the insulin secretion/glucose concentration dose-response curve) was determined by mathematical modeling. The incretin effect was defined as the oral-to-intravenous ratio of responses. In 8 subjects with NGT and 10 with diabetes, oral glucose appearance was measured by the double-tracer technique. RESULTS: The incretin effect on total insulin secretion and beta-cell glucose sensitivity and the GLP-1 response to oral glucose were significantly reduced in diabetes compared with NGT or IGT (P or (literal)
