What is it?

Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) refers to a condition which is characterized by secretion of too much vasopressin by the pituitary gland. Vasopressin causes the body to retain fluid, thus diluting the blood and causing low sodium levels. SIADH may be caused by certain types of tumors, brain conditions such as meningitis and encephalitis, lung diseases, and certain medications.
