Usually polyurea is a sign of diabetes. When you become diabetic, the high glucose in the blood spills into the urine and it drags water with it. There's also a disease where you don't make vasopressin at all called diabetes and sepidus. But if you see a person who's got one of those huge water bottles and they're drinking it avidly, they probably go to the bathroom more than you and I do. That means you're perhaps because I know you're not diabetic. that I can guarantee.
