Fig. 2: Postprandial gut hormone and metabolite responses.

Postprandial dynamics during the 360-min mixed meal test for plasma A glucagon-like peptide-1 (GLP-1), B secretin, C glucose, D insulin, and E C-peptide at baseline and at 6 and 12 months after Roux-en-Y gastric bypass (RYGB, red) and one anastomosis gastric bypass (OAGB, blue). Data are shown as pooled medians with interquartile ranges. Units are indicated on the Y-axis; sampling time points (minutes) are shown on the X-axis.
