Is your eyesight cloudy for no reason? High blood sugar levels can change the shape of the lens and affect vision. If this comes up regularly, talk to your doctor.
Dry mouth
The feeling of dry mouth, often accompanied by intense thirst, may indicate that your body is losing too much fluid due to the elimination of sugar through the urine.
