Abstract

Primary polydipsia is a clinical status with excessive fluid consumption without any physiological need. A seventeen-month-old male infant with severe malnutrition and developmental retardation was found to have polyuria and polydipsia in the follow-up. The urine density was found to be 1001, Na was found to be 124 mEq/L and the serum and urine osmolarity was found to be low. The patient was diagnosed with primary polydipsia and was treated by gradually water restriction. This case is presented to emphasize that primary polydipsia changes nutritional habits which may lead to malnutrition and developmental retardation.
