Syndrome of inappropriate ADH (SIADH) secretion is a disorder of fluid and electrolyte balance which results from the excessive release of antidiuretic hormone (ADH).

SIADH is seen in association with certain cancers (for example oat cell lung cancer, pancreatic, prostate, Hodgkin's disease), central nervous system disorders, head injury, myxoedema, psychosis and certain drugs.
