Dexcom G7 Sensor 15 Day
The Dexcom G7 Sensor 15 Day is a continuous glucose monitoring (CGM) sensor that provides real-time glucose readings every 5 minutes and optional high- and low-glucose alerts. Designed for up to 15 days of wear, it offers improved accuracy, a compact design, and integration with the Dexcom G7 mobile app for seamless glucose management.
About this item
The Dexcom G7 Sensor 15 Day offers continuous glucose monitoring with optional real-time alerts for high, low, and urgent-low glucose levels. The sensor is worn on the back of the upper arm and continuously measures glucose in interstitial fluid, providing updates every 5 minutes.
Users can view glucose values, trend arrows, and up to 8 hours of historical data using the Dexcom G7 mobile app or compatible reader. The extended 15-day wear duration reduces sensor changes, improving convenience for daily diabetes management.
The sensor is small, discreet, and water-resistant, designed to remain in place during normal daily activities such as showering, exercising, and sleeping. It features a simple one-piece applicator for easy insertion. Real-time alerts help users respond promptly to unexpected glucose fluctuations.
Important: Always follow Dexcom’s instructions for sensor use. If glucose readings do not match symptoms, verify with a blood glucose meter before making any treatment decisions.
