Normal Blood Sugar Count

A normal blood sugar count for an active, young person without diabetes is 4.7. Blood sugar levels should not dip below 4.0 millimoles per liter (mmol/L), even after eating or exercising. Blood sugar tests are used to measure how the body processes sugar (glucose).

Fast Facts:

  • Blood sugar tests should be completed upon waking, immediately before breakfast, before each meal, two hours after each meal, and at bedtime.
  • Blood sugar levels of 7.0 mmol/L or higher are often seen in diabetics.
  • There can be some variation in normal results.
