What leads to polydipsia in diabetes?

Explanation:
Polydipsia in diabetes comes from dehydration caused by osmotic diuresis due to high blood glucose. When glucose is very elevated, the kidneys can’t reabsorb it all, so glucose spills into the urine. Water follows that glucose into the urine, increasing urine volume. The resulting fluid loss leads to dehydration, which stimulates the thirst centers in the brain, producing increased drinking. The other ideas don’t fit the sequence: urination from dehydration would be a consequence, not the initiating cause; lack of thirst would not explain driving to drink; and water retention from kidney failure wouldn’t account for the characteristic thirst.
