Overview

Syndrome of inappropriate antidiuretic hormone (SIADH) occurs when an excessive amount of antidiuretic hormone is released resulting in water retention and a low sodium level. It is most common among older people. It has many causes including, but not limited too, pain, stress, exercise, a low blood sugar level, certain disorders of the heart, thyroid gland, kidneys, or adrenal glands, and the use of certain medications. Disorders of the lungs and certain cancers may increase the risk of developing SIADH. Treatment includes fluid restriction and sometimes the use of medications that decrease the effect of antidiuretic hormone on the kidneys.[1]
