Overview
Diabetes insipidus can be classified into 3; central, nephrogenic, and psychogenic diabetes insipidus which is due to a defect in water balance leading to the excretion of large volumes of dilute urine (urine osmolality usually below 250 mosmol/kg). Some rarer types of diabetes insipidus include gestational diabetes insipidus which occurs only in pregnancy and autoimmune diabetes insipidus caused by an autoimmune reaction.
Classification
Central DI: CDI is caused by the destruction or degeneration of neurons originating in the supraoptic and paraventricular nuclei. Central DI, results from damage to the pituitary gland, which disrupts the normal storage and release of ADH. The most common cause of central diabetes insipidus (CDI), accounting for the vast majority of cases, are idiopathic diabetes insipidus (DI)[1][2].
Nephrogenic DI: The most common causes of ADH resistance severe enough to produce polyuria are hereditary nephrogenic DI in children, and chronic lithium ingestion and hypercalcemia in adults. Acquired causes are often partially reversible with cessation of the offending drug or correction of hypercalcemia.[3][4][5][6][7][8]
Psychogenic Diabetes insipidus: is characterized primarily by an excess of water intake. This disorder is most often seen among young women and mentally unstable patients with psychiatric illnesses, including those taking a phenothiazine which can lead to the sensation of a dry mouth. Other identifiable causes of psychogenic diabetes insipidus are sarcoidosis and lesions to the hypothalamic pituitary axis which may disrupt the thirst center thereby increasing the sensation of thirst and water consumption.
Gestational diabetes insipidus: This type of diabetes insipidus occurs only in pregnancy. Gestational DI occurs when an enzyme made by the placenta destroys ADH produced in the mother. Most cases of gestational DI can be treated with desmopressin. In rare cases, however, an abnormality in the thirst mechanism causes gestational DI, and desmopressin should not be used.
Autoimmune diabetes insipidus: This type of diabetes insipidus is very rare. It is due to an autoimmune cause. It is usually associated with other autoimmune diseases and typically affects women of child-bearing age.
