What You Need to Know About the Dexcom G7 Sensor: Features, Accuracy & Benefits

For individuals managing diabetes, real-time insights into glucose levels are critical for making informed treatment decisions. A new Dexcom innovation—the Dexcom G7 Continuous Glucose Monitoring System—is changing how people monitor and manage blood sugar. Whether you’re a long-time Dexcom user or considering switching from fingersticks, here’s what to know about the G7’s features, accuracy, and benefits.

What is the Dexcom G7 Sensor?

The Dexcom G7 is part of the latest generation of continuous glucose monitoring (CGM) systems. Smaller, faster, and more powerful than the G6, the G7 provides real-time glucose readings without the need for fingersticks^*.

The sensor pairs with a compatible smartphone using the Dexcom G7 app, delivering continuous updates that support smarter diabetes management for both Type 1 and Type 2 diabetes.

Key Features of the Dexcom G7

• All-in-One Sensor and Transmitter: A compact, disposable unit that simplifies the insertion and setup process.
• 30-Minute Warm-Up: Ready for use in just 30 minutes—significantly faster than previous models.
• 12-Hour Grace Period: Allows extra time after the 10-day wear period to replace the sensor at your convenience.
• Improved Accuracy: Enhanced performance helps support treatment decisions with greater confidence (based on Dexcom data).
• Smart Device Compatibility: Works with many iOS and Android smartphones and smartwatches. Check device compatibility at dexcom.com/compatibility.

Using the G7 App

The Dexcom G7 app displays your current glucose reading, trend arrows, and a 24-hour glucose history. It also delivers customizable alerts to notify you of highs, lows, or rapid changes.

You can share data with caregivers and healthcare professionals, helping you work together on personalized care strategies. The G7 app is a central part of the Dexcom experience and is required for full functionality.

Dexcom G7 vs. Traditional Glucose Meters

Unlike traditional blood glucose meters, which provide a single reading, the Dexcom G7 offers up to 288 glucose readings per day. This continuous data helps identify trends, avoid dangerous highs and lows, and understand how food, exercise, and medication affect your glucose levels throughout the day.

Who Might Benefit from the Dexcom G7?

The Dexcom G7 may be a good fit for individuals who:

• Want to reduce or avoid routine fingersticks
• Need more data to support insulin or treatment decisions
• Prefer a convenient, discreet way to monitor glucose
• Use a compatible smartphone or wearable device

The Dexcom G7 is designed to make diabetes management more intuitive by reducing the burden of fingersticks^* and offering continuous, real-time glucose data. If you’re looking for a simpler way to monitor your levels, respond to trends, and stay in better control of your day, a CGM like the G7 may be worth exploring.

This system can be especially helpful for people who:

• Have difficulty recognizing blood sugar highs or lows
• Want more information to support their insulin or food decisions
• Prefer using smartphones or smartwatches for tracking health data
• Are trying to reduce the guesswork in diabetes management
