Diabetes Insipidus

Medical Definition: A disease that is characterized by frequent urination, excretion of large amounts of dilute URINE, and excessive THIRST. Etiology of diabetes insipidus include deficiency of ANTIDIURETIC HORMONE (also known as ADH or VASOPRESSIN) secreted by the PITUITARY, impaired KIDNEY response to ADH, and impaired hypothalamic regulation of thirst.

Canadian Medical Guide Definition Diabetes Insipidus, Nephrogenic - A polyuric disorder characterized by normal rates of renal filtration and solute excretion, but a persistent hypotonic urine. This condition is due to the failure of renal tubules to respond to antidiuretic hormones, such as vasopressin, to reduce urine volume. Tubular insensitivity to vasopressin can result from genetic defects, diseases, drug effects, or may occur with pregnancy.
