Summary
This study tested whether infusing mannitol, a sugar alcohol, can help diagnose polyuria-polydipsia syndrome—a condition of excessive thirst and urination. Researchers measured copeptin levels in 42 healthy adults and patients after mannitol or placebo infusion. The goal was to see if copeptin responses differ between healthy people and those with specific thirst disorders, potentially improving diagnosis.
