Simple Meal Management Using Automated Insulin Delivery System

Summary

Carbohydrate counting is an essential component of diabetes management in both adults and children, and together with an intensive insulin plan and increased blood glucose monitoring was associated with lower HbA1c. Carbohydrate counting is perceived as one of the most burdensome tasks in T1D and is frequently done inconsistently and with poor accuracy A recent analysis confirms that MiniMed™ Advaced Hybrid closed loop (AHCL) system is designed for optimal performance with meal announcement. Nonetheless, when meals containing \< 80 grams of carbohydrates are consumed with announcement of meals at will, there is a slight reduction in the number of daily boluses with no decline in glycemic control, yet markedly less diabetes related distress and improved treatment satisfaction TIR of 78.1% in unannounced meals compared with 78.8% with announced meals .
