Get checked: Have your doctor check a urine test. Its the easiest start.

Urinalysis: Start with measuring your fluid intake and urine output in 24 hours. If your urine volume is way out of proportion to your fluid intake, a urinalysis and blood tests for kidney function and electrolyte and calcium and blood sugar status should be done to start with. Discuss this with your physician.
