Syndrome of Inappropiate Antidiuretic Hormone (SIADH) is a condition caused by excessive antidiuretic hormone (ADH) secretion.High level of ADH increse water reabsorption in the kidney. This syndrome is characterized by hyponatremia, plasma hypo-osmolality,urine osmolality less than 100 mOsm/kg, elevated urine sodium, euvolemia, with normal renal, adrenal, and thyroid function. SIADHcould be the result of ectopic ADH caused by malignant cells, drug-induced, baroreceptor lesion, and other problems. Main treatmentfor SIADH is intended to overcome the underlying diseases.
