What causes polydipsia in diabetes and how can we treat it?

Polydipsia is the medical term for excessive thirst. When a person with diabetes develops a high blood sugar level, the kidneys cannot reabsorb all of the sugar passing through it. The excess sugar in the urine pulls out excess water from the body, leading to increased urination known as polyuria. The excessive thirst is essentially due to dehydration. Keeping blood sugar levels controlled will stop the symptoms.
