Blood Sugar Diary
When you keep a blood sugar diary to track and monitor your blood sugar levels, you and your doctor
will be able to make better decisions about your diabetes treatment plan. Before you start tracking your
blood sugar levels in your diary, you may wonder when and how often you should check your blood sugar.
Be sure to follow your doctor’s instructions.
Many people starting on insulin may check their blood sugar several times a day—when they wake up and after each meal.
- When you wake up, begin tracking your fasting blood glucose level. This is usually done in the morning before you eat anything. It is best to check if you haven’t had anything to eat in at least 8 hours
- After you eat, track your postprandial blood glucose level. This test is usually taken 2 hours after you eat. It measures how much your blood sugar level has risen due to the food you ate. Discuss with your doctor how often you should monitor your blood sugar at home
