Brief Summary

Glucagon like Peptide -1 (GLP-1) receptor agonists are well known to stimulate glucose-induced insulin secretion and to reduce energy intake. Recent findings from animal and human studies suggest a role of GLP-1 in regulating water and salt homeostasis. GLP-1 has been shown to reduce fluid intake after an oral salt load or during a meal - pointing to a hypodipsic effect. The aim of this study is to elucidate whether these putative hypodipsic properties of GLP-1 might be of advantage in persons with an exaggerated thirst perception as is the case in patients with primary polydipsia.
