Numbness
If you start feeling numbness as a tingling in the fingers, feet, hands, and legs this is an early warning sign of diabetes. This happens due to an increase in your blood sugar levels which cause blood vessel restriction to the extremities and eventually damage to nerve fibers.
Increased urination
Those who suffer from diabetes claim they had an overwhelming urge to urinate. This is also an early sign of diabetes and this increased urination will often result in severe dehydration. You better keep your fluid levels high, because it is vital.
