Summary
This study looked at whether taking a fast-acting insulin (Insulin Aspart) before or after meals makes a difference in blood sugar control for people with type 1 diabetes who use an insulin pump. Twenty-two adults participated, and their blood sugar was tracked continuously for 14 days. The goal was to see if injecting after meals, which many patients already do, is a safe and effective option.
