what means polydipsia
Polydipsia is excessive thirst. The word derives from the Greek ÏÎ¿Î»ÏÎ´Î¹ÏÎ¯Î±, which is derived from ÏÎ¿Î»ÏÏ (polys, much, many) + Î´Î¯ÏÎ± (dipsa, thirst). Polydipsia is a nonspecific symptom in various medical disorders. It also occurs as an abnormal behaviour in animals.olydipsia is a symptom (evidence of a disease state), not a disease in itself. As it is often accompanied by polyuria, investigations directed at diagnosing diabetes insipidus and diabetes mellitus can be useful.
