What are the physiologic mechanisms involved in polydipsia polyuria and polyphagia in diabetes mellitus?
In Diabetes mellitus, glucose can't enter the body's cells from the blood, since insulin is low (or ignored). Blood glucose begins to rise. When blood glucose gets high enough, it passes the 'renal threshold' for sugar. (In humans this is between 180 and 220 mg/dL.) The kidneys are then obliged to filter out glucose and excrete it with the urine.
At this point, the urine becomes too concentrated and osmosis pulls extra water into the urine from the body, leading to the polyuria symptom. The resulting dehydration makes the victim thirsty -- this is the polydipsia system.
The sugar being wasted by the kidneys means the body is not nourished, even with enough food intake. This leads to excess hunger or polyphagia.
