Continuous glucose monitors (CGMs) have revolutionized diabetes management, offering real-time blood sugar tracking without the need for fingersticks. With the release of the Dexcom G7, many are wondering how it compares to the Dexcom G6. Below, we break down the key differences and improvements between the two models.
Size & Design
One of the most noticeable upgrades in the Dexcom G7 is its smaller size. It is Dexcom’s smallest sensor yet, measuring 1.07 inches wide by 0.94 inches long, compared to the G6’s 1.2 inches wide by 1.8 inches long. Additionally, the G7 integrates both the sensor and transmitter into a single unit, eliminating the need for a separate transmitter like in the G6.
Sensor Lifespan & Warm-Up Time
Both the Dexcom G6 and G7 have a 10-day wear time, but the G7 offers a 12-hour grace period at the end of its lifespan, allowing users extra time before replacing the sensor. Another major improvement is the warm-up time—the G7 is ready in just 30 minutes, compared to the G6’s 2-hour warm-up period.
Alerts & Customization
Both sensors come equipped with customizable high and low alerts, urgent low alerts, and urgent low soon alerts to help users manage their blood sugar levels effectively. However, the G7 introduces “Delay First Alert,” which allows users to postpone their first notification if they’re already actively managing their glucose levels.
Wear Locations
The wear locations have changed slightly between the two models. The Dexcom G7 is worn on the back of the upper arm for adults, while the Dexcom G6 can be placed on the abdomen or upper buttocks (for children 2-17 years old). The G7’s updated placement options provide users with added flexibility and comfort.
Waterproofing & Durability
Both sensors are waterproof up to 2.4 meters for 24 hours, making them suitable for showering, swimming, and other water activities without concern.
Connectivity & Apps
The Dexcom G7 and G6 both connect to iOS and Android smartphones, as well as the Dexcom Follow App for sharing data with caregivers or family members. However, the G7 introduces direct connectivity to Apple Watch, eliminating the need for a paired smartphone. This feature is a significant step forward for users who want more seamless glucose tracking on the go.
Who Should Upgrade?
The Dexcom G7 offers faster warm-up time, a more compact design, and improved alert features, making it a great choice for those looking for enhanced convenience. However, if you are comfortable with the G6 and its placement options, you may find it sufficient for your needs.
Ultimately, both CGMs provide accurate, real-time glucose monitoring, and choosing between them depends on your personal preferences and lifestyle. Whether you stick with the Dexcom G6 or upgrade to the Dexcom G7, both devices help streamline diabetes management for a healthier, more informed life.
