Abstract

Syndrome of inappropriate diuretic hormone secretion (SIADH) involves a deficit of water excretion due to the inability to suppress antidiuretic hormone (ADH) secretion. It should be considered in hyponatremia with hypoosmolality, urinary osmolality greater than 100 mOsm/kg, urinary sodium concentration greater than 40 mEq/L with thyroid, renal and adrenal norm-function. We present the case of a 81-year-old female patient admitted to Psychiatry for bipolar disorder with hyponatremia secondary to pharmacological SIADH due to psychiatric medication. Given the need for maintenance of psychiatric treatment, chronic treatment with urea was agreed to avoid secondary hyponatremia.
