The compact design of the G7 also extends to its inserter device, which has been redesigned to be more user-friendly and convenient. The new inserter device is expected to make the insertion process easier and less painful, which can benefit people with diabetes who have to insert sensors frequently.

Overall, the Dexcom G7 significantly improved over its predecessors, offering better technology, longer wear time, and a more compact and user-friendly design.

Unsurprisingly, this device has earned more popularity than its predecessors, as it represents a significant step forward in the development of CGM technology and is likely to improve the lives of many people with diabetes.

Some of its notable features and benefits Are.

  • 10-day lifespan
  • Smallest Dexcom sensor
  • All-in-one sensor and transmitter
  • 30-minute warm-up
  • 12-hour grace period

Comparison of Dexcom G6 Vs G7

When choosing between the Dexcom G6 and G7, several factors must be considered. Let’s take a closer look at some of the key differences between the two devices.

  • Design & appearance
  • Accuracy & reliability
  • Connectivity & compatibility
  • Price & insurance coverage

Design & appearance

One of the most noticeable differences between Dexcom G6 and G7 is their design and form factor. Dexcom G6 has a larger transmitter compared to G7. Additionally, G7 is designed to be thinner and more flexible than G6. This makes G7 more comfortable to wear and less bulky.

Accuracy & reliability

The Dexcom G7 and G6 are both Continuous Glucose Monitoring (CGM) devices that offer high accuracy and reliability in monitoring glucose levels in people with diabetes. However, G7 is expected to be even more precise than its predecessor, the G6, due to its improved sensor technology.

The Dexcom G7 sensor is about 60% smaller than the G6’s sensor, which allows for more precise measurements of glucose levels in the interstitial fluid.

Connectivity & compatibility

The Dexcom G6 and G7 CGM devices are compatible with smartphones and smartwatches. However, the G7 offers more flexibility and convenience to users, as it can be directly connected to the phone without needing a separate receiver.

Overall, the direct connectivity feature of the G7 offers more flexibility and convenience to users compared to the G6, making it a popular choice among people with diabetes who value ease of use and flexibility in their CGM devices.

Price & insurance coverage

The Dexcom G7 is a continuous glucose monitoring system (CGM) expected to be priced similarly to its predecessor, the Dexcom G6. However, while the initial cost of the G7 may be like the G6, the G7 is expected to have more accuracy, making it a more cost-effective option in the long run.

This is because having a more accurate glucose monitoring system can help people with diabetes better manage their blood sugar levels, potentially reducing the need for costly medical interventions or hospitalizations.

It is important to check with your insurance provider to see which device your plan covers as insurance coverage for both devices may vary. Some insurance plans may cover the cost of either the G6 or G7, while others may only cover one or the other.

Additionally, insurance coverage can change over time, so it’s a good idea to check periodically to see if your plan covers the device you prefer.

Which one is best to buy

If you want to purchase a continuous glucose monitoring (CGM) system, the Dexcom G7 may be the best option. While the G6 and G7 have their strengths and weaknesses, the G7 offers several improvements that make it the better choice for most people.

One of the most significant advantages of the G7 is its smaller size. The G7 sensor is 60% smaller than the Dexcom G6 sensor, making it less intrusive and more comfortable to wear. This smaller size also makes it easier to insert and remove the sensor, which is a significant benefit for people new to CGM systems.

Finally, the G7 offers a simpler and more streamlined insertion process. Unlike the Dexcom G6, which requires a separate applicator and sensor, the G7 sensor comes pre-loaded with an applicator, making it easier and more convenient to insert.

Overall, the Dexcom G7 offers several advantages over the G6, including a smaller size, longer wear time, enhanced accuracy, and a simpler insertion process. If you’re in the market for a new CGM system, the G7 is definitely worth considering.


Choosing a suitable CGM device can be a daunting task. Still, you can make an informed decision with the correct information and guidance. The Dexcom G6 and G7 are excellent CGM devices offering advanced features and benefits to people with diabetes.

While the G6 has been in the market for a while and has a proven track record, the G7 promises to be even more advanced and user-friendly. Depending on your personal needs and preferences, you may choose either device. We recommend consulting with your healthcare provider and insurance provider before deciding.
