How CGM technology revolutionizes diabetes management

A continuous glucose monitor is a small wearable device that automatically tracks your glucose levels 24/7, providing real-time data without painful fingersticks. Unlike traditional glucose testing, CGM technology uses a tiny sensor inserted under your skin to measure glucose in your interstitial fluid every few minutes. This data is sent to your smartphone or receiver, showing trends, patterns, and alerts for high or low blood sugar levels. Learn more about how continuous glucose monitors work.
