2. Fig. 1
Schematic of the procedure for combined hyperglycemic-euglycemic clamp and hyperglycemic clamp, coupled with tracer methodology and GLP-1 (7–36) amide infusion. Abbreviations: GLP-1 = glucagon-like peptide-1; IV = intravenous.

3. Fig. 2
Plasma glucose (top panel), insulin (middle panel), and active GLP-1 (7–26) amide (bottom panel) profiles of STM before and at 1, 3, 6, 9, 12, and 15 months after RYGB. Times when STM was administered are indicated by symbols in the middle panel and n for each test is provided in Table 1. Abbreviations: Pre = presurgery; GLP-1 = glucagon-like peptide-1.

4. Fig. 3
Plasma glucose profiles (top panel) during the combined hyperinsulinemic-euglycemic clamps and hyperglycemic clamps before surgery (circles) and at 12 months after surgery (triangles). The bottom panel represents the glucose infusion rates during presurgery and postsurgery clamps. The shaded area from 0 to 120 minutes indicates the period when insulin was infused, and the area from 240 to 300 minutes when GLP-1(7–26) amide was infused. Abbreviations: Pre = presurgery; GLP-1 = glucagon-like peptide-1.

5. Fig. 4
Plasma insulin levels during the combined hyperinsulinemic-euglycemic clamps and hyperglycemic clamps before surgery and at 1, 3, 6, and 12 months after surgery. Because of robust insulin response during GLP-1 (7–36) amide infusion, it is necessary to have an expanded insulin scale, which makes it difficult to discern the first-phase insulin response during the hyperglycemic clamps at 0 to 10 minutes. Abbreviation: Pre = presurgery.

6. Fig. 5
First- and second-phase insulin responses during the first hour of the hyperglycemic clamp when only glucose was infused. Abbreviation: Pre = presurgery.

7. Fig. 6
Rates of glucose metabolism, insulin response, and M/I when both glucose and GLP-1 (7–36) amide were infused during the hyperglycemic clamp (90–120 minutes). Asterisks indicate P<.05 compared with presurgery values (Table 2). Abbreviations: M = metabolism; I = insulin response; M/I = metabolism/insulin.

8. Fig. 7
Hepatic glucose production rates before surgery and 1 and 3 months after surgery. Ra was completely suppressed by 3 months during the hyperinsulinemic-euglycemic clamps and at all subsequent visits. Abbreviations: pre = presurgery; Ra = rate of glucose appearance.
