Blood sugars: If you have normal insulin function, a normal blood sugar from 2- 4 hours after a meal should be 70 to 90. When you allude to the guideline of a normal 2 hour postprandial blood sugar of less than 140, this applies to the test of drinking a heavy glucose load as in a glucose tolerance test.
