Question from Green Bay, Wisconsin, USA:

My daughter is 9 and has had diabetes for 7 years. (She weighs 55 pounds.) What could explain the fact that 2 weeks ago she was getting 1 or 2 units of Humalog in the morning along with 15 units NPH, nothing at lunch and by supper she had been running low (50’s)? I was not giving any supper insulin and by 8�P.M. she would be 60-80 range, she’d have a snack (30 grams carb) and skipped bedtime NPH which had always been 1/2 unit and by midnight she’d again be 55-85 then 60’s at breakfast. This went on for at least 2 weeks. Then the A.M. was getting higher, 160+, so we are back to 3 shots per day and now I can’t seem to get any of the numbers below 200. She is now taking 5-6 units Humalog and 12 NPH in the morning and 1-3 units Humalog at supper and 1 unit at bedtime (9:30�P.M.) Do you have any explanations?
