Wearable Glucose Monitors: Insights and Limitations for Non-Diabetics
Continuous glucose monitors, traditionally used by diabetics, are now available over-the-counter in the U.S. and are being used by non-diabetics to track glucose levels in real-time. These devices provide minute-by-minute data on how glucose levels respond to food and physical activity. While they offer insights into personal health and can motivate lifestyle changes, experts caution that the data can lead to confusion and anxiety without proper interpretation. The technology has evolved from test strips to advanced non-invasive sensors, and while beneficial for diabetics, the utility for non-diabetics remains unclear due to the lack of guidelines for interpreting glucose fluctuations in healthy individuals.
