A Case of Polydipsia in a Psychiatric Patient

A 28 year old male student, with a long standing history of psychotic disorder, presented with excessive water intake and symptom exacerbation with associated confusion, vomiting and irrational talk, that has started a week before. He drank about 20 L of water daily and had dyselectrolytaemia. He was admitted and managed as a case of Diabetes Insipidus with no improvement until after an inadvertent psychiatric evaluation and management when the correct diagnosis was made. This case is the first to be reported in this country and a learning point for psychogenic polydipsia.
