Diabetes insipidus

Definition of Diabetes insipidus

Diabetes insipidus is a condition in which the kidneys are unable to conserve water.

Causes, incidence, and risk factors

Diabetes insipidus (DI) is an uncommon condition that occurs when the kidneys are unable to conserve water as they perform their function of filtering blood. The amount of water conserved is controlled by antidiuretic hormone (ADH), also called vasopressin.

Treatment

The cause of the underlying condition should be treated when possible.

Expectations (prognosis)

The outcome depends on the underlying disorder. If treated, diabetes insipidus does not cause severe problems or reduce life expectancy.
