Buddy system for blood sugar: study shows promise in preventing diabetic emergencies
NCT ID NCT06114186
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a program called FAM that helps adults with type 1 diabetes avoid dangerously high blood sugar, which can lead to diabetic ketoacidosis (DKA). The program involved sharing real-time glucose data with a family member or friend (the Follower), creating an action plan, and providing education. 22 adults at high risk for DKA participated. The goal was to see if this support system could reduce time spent with very high blood sugar levels.
