What is a normal blood sugar level?
What are normal blood sugar levels? Normal blood sugar levels are less than 100 mg/dL after not eating (fasting) for at least eight hours. And they're less than 140 mg/dL two hours after eating.
What does it mean if blood sugar level is higher than normal?
Hyperglycemia is a defining characteristic of diabetes—when the blood glucose level is too high because the body isn't properly using or doesn't make the hormone insulin. Eating too many processed foods may cause your blood sugar to rise.
