Syndrome of Inappropriate Antidiuretic Hormone Secretion

What is syndrome of inappropriate antidiuretic hormone secretion?

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) occurs when excessive levels of antidiuretic hormones (hormones that help the kidneys and body conserve the correct amount of water) are produced.

  • The syndrome causes the body to retain water and certain levels of electrolytes in the blood to fall (such as sodium).
  • SIADH is rare in children.

How we care for SIADH

Here at Boston Children’s Hospital, SIADH is treated through our General Endocrinology Program—a multidisciplinary program that provides comprehensive diagnosis, treatment and management for patients with disorders associated with the endocrine system.
