New insulin timing trick may tame blood sugar after pizza and burgers
NCT ID NCT05454891
First seen Jun 24, 2026 · Last updated Jun 24, 2026
Summary
This study tested whether giving insulin as an extended bolus (over time) instead of all at once helps control blood sugar after high-fat, high-protein meals in teens with type 1 diabetes. Thirty teens using a closed-loop insulin pump ate a standardized breakfast and received either an extended or standard bolus on different mornings. The goal was to see if the extended bolus reduces prolonged high blood sugar or early low blood sugar.
