Every morning at about 9:30, Leslie and all the other kids at her middle school with diabetes leave class and report to the school nurse’s office to check and then report their blood glucose levels. Today Leslie is a little low and requires some food in order for her to get her blood sugar back in the normal range. She is 65. This is her second blood glucose test of the day.
Knowing that Leslie’s blood sugar will rise 10 mg/dL for every 1 gram of carbohydrate she eats, she and the nurse figure out that she needs to eat something that contains between 6 – 10 grams of carbohydrate in order to get her back into the “zone” which will be both be safe and facilitate learning. She eats some peanut butter crackers and heads back to class.
If her blood sugar had been high instead of low, she would have had to take additional insulin to bring it down into the zone. Since it is still morning, the ratios would be the same as those in place when she awakened.
