NCT04651868

Brief Summary

The study is a randomized, double-blinded, placebo-controlled, cross-over study, which will investigate the acute effects of the gut-derived hormone glucagon-like peptide 2 (GLP-2) on cholecystokinin (CCK)-induced gallbladder emptying. Furthermore, the investigators will investigate different hormonal responses and appetite during the study days. The investigators hypothesize that GLP-2 will overrule the potent gallbladder relaxing effect of CCK. We will include 15 healthy male participants, and each of the participants will participate in four study days. GLP-2 and CCK will be given intravenously, and will be placebo-controlled. Gallbladder volume will be determined by frequent ultrasonography scans. Appetite will be assessed by Visual Analog Scales through out the study day and an ad libitum meal at the end of the study day. Blood samples will be drawn at regular intervals to asses different hormonal responses.
