Psychogenic polydipsia is a condition where the person consumes water in excess accompanied with psychogenic symptoms, mental illness and developmental disability there is a psychosis. Many cases present with hyponatremia and its central nervous system manifestations. Here, we describe a case of psychogenic polydipsia presented with hyponatremia with convulsion. A 52-year-old male patient presented to our hospital with an episode of convulsion and had a history of irrelevant talks, visual hallucinations, decreased sleep, polydipsia since 2 months. On the day of admission, there was hyponatremia with serum sodium levels 114 mmol/L. He was diagnosed with psychogenic intermittent polydipsia (PIP). Patient was treated with antipsychotic drug along with IV fluids, anti-epileptics, and other supportive measures. PIP syndrome is a diagnosis of exclusion. Early diagnosis of polydipsia causing hyponatremia to be made so that consequences like seizures, coma and life threatening situations can be avoided.
