The Dexcom G7 is a next-generation continuous glucose monitoring (CGM) system designed for people with diabetes to track their blood glucose levels in real-time. Building on the success of previous Dexcom models, the G7 offers a smaller, more streamlined sensor and transmitter that is easier to apply and less intrusive for daily wear. It provides continuous glucose readings directly to a smartphone or compatible smart device, enabling users to monitor trends, receive alerts for highs and lows, and better manage their condition. The Dexcom G7 emphasizes convenience, accuracy, and comfort, helping users maintain optimal glucose control with minimal disruption to their daily lives.
