What to expect if I have Syndrome of inappropriate antidiuretic hormone  (Outlook/Prognosis)?
Prognosis of SIADH depends on the severity of the disease and the promptness of treatment. Prognosis of syndrome of inappropriate antidiuretic hormone (SIADH) also depends largely on its cause. If the cause is drugs, SIADH usually improves after stopping a drug. If SIADH is associated with some infection, treating the infection may be important. For those SIADH with cancers, the outcomes may be poor. </s>
