Syndrome of inappropriate antidiuretic hormone secretion

SIADH; Inappropriate secretion of antidiuretic hormone; Syndrome of inappropriate ADH release; Syndrome of inappropriate antidiuresis

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a condition in which the body makes too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water your body loses through the urine. SIADH causes the body to retain too much water.

ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.
