Insulin
Question from Pittston, Pennsylvania, USA:
My 14 year old son, who has had type 1 diabetes for three years, is currently taking Lantus and Humalog at breakfast, lunch, dinner before bed. We monitor every injection, and 72 hours on the Continuous Glucose Monitoring System revealed that his really high blood sugars in the morning are the result of the dawn phenomenon. We can’t adjust his insulin before bed because, during part of the night his sugars run around 60 mg/dl [3.3 mmol/L] and then they peak to 300-400 mg/dl [16.7-22.2 mmol/L]. Any suggestions?
Answer:
You might try splitting the Lantus (insulin glargine), giving more in the morning and less at bedtime. It has a peak, but with a smaller dose and a bedtime snack, this might be okay. Discuss with your son’s diabetes team.
