polydipsia

[pol′ēdip′sē·ə]
Etymology: Gk, polys + dipsa, thirst
1 excessive thirst. It is characteristic of several different conditions, including diabetes mellitus, in which an excessive concentration of glucose in the blood osmotically pulls intracellular fluid into the bloodstream and increases the excretion of fluid via increased urination, which leads to hypovolemia and thirst. In diabetes insipidus the deficiency of the pituitary antidiuretic hormone results in excretion of copious amounts of dilute urine, reduced fluid volume in the body, and polydipsia. In nephrogenic diabetes insipidus there is also copious excretion of urine with consequent polydipsia. Polyuria resulting from other forms of renal dysfunction also leads to polydipsia. The condition also may be psychogenic in origin.

compensatory polydipsia
one caused by an obligatory polyuria.
drug-induced polydipsia
diuretics, corticosteroids, salt, vitamin D, and megestrol acetate may cause a polyuria and, secondarily, a polydipsia.
primary polydipsia
excessive water drinking in hyperactive, stressed dogs. See also psychogenic diabetes insipidus.
psychogenic polydipsia
horses confined in a stall and having little or no exercise may drink excessively from boredom, up to three times normal amounts. It may also occur in dogs, apparently from psychological causes, with large amounts of water a day being consumed and a corresponding polyuria with a large volume of dilute urine produced. Yet, when water intake is restricted normal tubular function with concentration of urine is possible. See also psychogenic diabetes insipidus.
