Presentation:
This case report was from a patient who was a long-term resident from the Center of Behavioral Medicine (CBM) with the primary diagnosis of Schizophrenia, alcohol use disorder, Stimulant use disorder (methamphetamine), Hallucinogen use disorder (LSD), and Cannabis use disorder. He stayed in the CBM for years without remarkable physical complaint initially. One day he went to Gastroenterology (GI) clinic with CBM staff for routine work-up after treating his asymptomatic hepatitis C, and he told the gastroenterologist that he was craving for water with epigastric pain. Further work-up revealed he had mild bilateral hydroureteronephrosis through abdominal CT and chronic hyponatremia through repeated comprehensive chemical panel (CMP). Further monitoring indicated he had approximately 15 L urine output every day. Then he was diagnosed with Psychogenic polydipsia by multiple-discipline team using deprivation test with and without desmopressin. This presentation’s goals are to introduce clinical features of Psychogenic polydipsia, its gold diagnostic test and differential diagnosis, and its management plan (especially for patients with chronic and/or severe mental illness).
Objectives:
- Introduce clinical features of Psychogenic polydipsia.
- Understand the diagnostic criteria for Psychogenic polydipsia and its related differential diagnosis.
- Understand the comprehensive approaches to manage Psychogenic polydipsia
