PIP syndrome includes which features?

PIP syndrome includes which features?

• A. Polydipsia, intermittent hyponatremia, and psychosis
• B. Polyphagia, hyperglycemia, and fatigue
• C. Polydipsia, hypernatremia, and depression
• D. Polyuria, dehydration, and dizziness

Answer: (A)

Polydipsia drives excessive water intake in some individuals with schizophrenia, which can dilute serum sodium and cause intermittent hyponatremia. The psychosis component reflects the underlying psychiatric illness. Together, these three features—polydipsia, intermittent hyponatremia from water intoxication, and psychosis—form the PIP pattern. Other options mix in symptoms not specific to this syndrome, such as polyphagia with hyperglycemia (diabetes-related), polyuria with dehydration (diabetes insipidus or dehydration), or depression, which isn’t part of the characteristic triad.
