Polyuria is a urinary disorder characterized by an increase in the quantity of urine passed in one day. It is usually referred to in cases of diuresis, where measured urine quantities passed in 24 hours exceed 3 liters per day for adults, and 50 milliliters per kilogram of weight for children. Polyuria is not a disease in itself, but a symptom associated with many different conditions. There are, in fact, many different possible causes for this condition, including diabetes insipidus or mellitus, excessive consumption of fluids, kidney failure, diuretic medication, hormonal disorders, and so on. Polyuria is also associated with risks of dehydration, even if it is often compensated by an increased sense of thirst and thus consumption of water, called polydipsia.
