Can the 'love hormone' calm anxiety in diabetes insipidus?
NCT ID NCT06036004
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a nasal spray containing oxytocin can help reduce anxiety and improve emotional well-being in adults with central diabetes insipidus, a condition where the body lacks a key hormone. Participants will receive either oxytocin or a placebo spray for several weeks. The goal is to see if oxytocin can ease psychological symptoms beyond standard hormone replacement.
