Summary

This study tests whether wearing a continuous glucose monitor (CGM) alongside lifestyle changes can improve insulin sensitivity in teens aged 10-17 with prediabetes. Fifteen overweight or obese participants will use the Dexcom G7 device to see real-time glucose data, aiming to boost adherence to diet and exercise. The goal is to reduce the risk of developing type 2 diabetes and other obesity-related complications.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If it works, this could show that real-time glucose feedback helps teens stick to healthier habits and lower their risk of type 2 diabetes.
What could go wrong: This is a very small early study (15 participants) with no control group, so results may not be conclusive or generalizable.
