Wearable glucose monitor may supercharge lifestyle change in prediabetes
NCT ID NCT06841796
First seen Aug 18, 2026 · Last updated Aug 19, 2026 · Updated 1 time
Summary
This trial tests whether adding a real-time continuous glucose monitor (CGM) to a YMCA healthy lifestyle program helps adults with prediabetes improve their glucose levels, diet, and physical activity. Participants attend health coaching sessions and YMCA classes, with some wearing a CGM that shows their glucose data in real time for 24 weeks, while others wear a blinded monitor. The study compares changes in time spent in a healthy glucose range, dietary scores, and activity levels between the two groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Real-time continuous glucose monitor (CGM) device
- What this could lead to
- If it works, this could point toward a practical, community-based way to help people with prediabetes improve their glucose control and daily habits.
- What could go wrong
- This is a small, early-stage trial, so results may not apply broadly. Wearing a CGM could be inconvenient, and the device's accuracy and user engagement may vary.
