What Is Polydipsia?

Polydipsia

Say: pah-lee-DIP-see-uh

If diabetes isn't under control, a person might be really thirsty and drink a lot of fluids. Polydipsia is the medical word for this. In diabetes, polydipsia happens because the person's blood sugar levels are high and the kidneys are working overtime to get rid of the sugar. To do this, the kidneys make more pee. A lot of fluid leaves the body in pee, so the person feels really thirsty and tries to replace the fluid by drinking a lot.
