<unk>  <unk>  is a condition characterized by large amounts of<unk> lute urine and increased thirst. The amount of urine produced can be nearly 20 liters per day. Reduction of fluid has little effect on the concentration of the urine. Complications may include dehydration or seizures. There are four types of<unk> , each with a<unk> fferent set of causes. Central<unk>  (CDI) is due to a lack of the hormone vasopressin (antidiuretic hormone). This can be due to injury to the hypothalamus or pituitary gland or genetics. Nephrogenic<unk>  (NDI) occurs when the kidneys do not respond properly to vasopressin.<unk> psogenic<unk>  is a result of excessive fluid intake due to damage to the hypothalamic thirst mechanism. It occurs more often in those with certain psychiatric<unk> sorders or on certain medications. Gestational<unk>  occurs only during pregnancy.<unk> agnosis is often based on urine tests, blood tests and the fluid deprivation test.<unk>  is unrelated to<unk> abetes mellitus and the conditions have a<unk> stinct mechanism, though both can result in the production of large amounts of urine. Treatment involves drinking sufficient fluids to prevent dehydration. Other treatments depend on the type. In central and gestational<unk> , treatment is with desmopressin. Nephrogenic<unk>  may be treated by addressing the underlying cause or by the use of a thiazide, aspirin or ibuprofen. The number of new cases of<unk>  each year is 3 in 100,000. Central<unk>  usually starts between the ages of 10 and 20 and occurs in males and females equally. Nephrogenic<unk>  can begin at any age. The term "diabetes" is derived from the Greek word meaning siphon.
