For most people, good blood sugar levels are:

On waking up (before breakfast) 80 to 120
Before meals 80 to 120
2 hours after meals 160 or less
At bedtime 100 to 140

Ask your healthcare provider what your blood sugar levels should be. If you have diabetes, print out this chart and record the blood sugar ranges that your doctor believes optimal for you.

On waking up (before breakfast) _______ to _______
Before meals _______ to _______

You and your health care provider will agree on when to check blood sugar using a blood glucose meter. You will do the tests yourself. Be sure to ask your health care provider or diabetes assistant to teach you how to use the meter.
