How High Can Blood Sugar Go To Be Normal?


If you have been showing signs of diabetes, or you are at risk for Type 2 Diabetes, you should have a blood glucose test done. This test will show you the amount of sugar in your blood and determine whether you are currently not diabetic, pre-diabetic, or have diabetes. How high can blood sugar go to be normal?

Blood sugar can be measured after fasting (not eating) for 8 hours, or as a random sample (measured any time during the day).

Normal blood sugar levels are:

  • Between 70 mg/dl and 100 mg/dl after fasting; or
  • Not more than 200 mg/dl for a random sample.

In people without diabetes, then, blood sugar should not normally be higher than 200 mg/dl.
