Of course a physical from a doctor would tell you if you have diabetes, but you would have to get a blood test to determine what your blood sugar levels are.

diabetes often has no symptoms or signs for a long time and is often missed by doctors until the thickened blood causes damage to the eyes, feet, etc

a physical examination wont necessarily spot it, a spot blood sugar test, taking into account when and what you last ate can diagnose diabetes, but a glucose tollerance test is the only sure way of checking for diabetes
