Dexcom G7 Sensor and Phone AppFor individuals managing diabetes, staying abreast of the latest advancements in continuous glucose monitoring (CGM) is crucial. Dexcom, a prominent name in the industry, has unveiled the Dexcom G7, building upon the success of its predecessor, the Dexcom G6. If you are contemplating whether to leap to the G7, this comparison will help you weigh the pros and cons of these two groundbreaking devices.

Advancements in Dexcom G7: A Closer Look

Released in early 2023, the Dexcom G7 offers several improvements over the G6 model. Let’s delve into the key features that set the G7 apart:

  • Size and Placement: The G7 patch is half the size of the G6, offering more flexibility in placement. You can comfortably wear it on the back of the arm or the abdomen. An additional option for children aged two and above is to place it on their upper buttocks. The G7’s transmitter continues to transmit effectively over a distance of 20 feet and even underwater.
  • Sensor Lifespan and Warm-up Time: While the G7 sensor has a lifespan of 10 days, it introduces a 12-hour grace period, allowing users some flexibility. Notably, the new G7 sensor significantly reduces the warm-up time from 2 hours to 30 minutes, enhancing coverage and efficiency.
  • Improved Alarms: The G7 alarms have undergone enhancements, allowing users to delay the first alert for a high reading. Users can personalize alarms to silence or vibration.
  • App Connectivity: The G7 streamlines connectivity by requiring only one app to connect up to 10 people and healthcare providers. The app offers comprehensive insights into sugar trends for various periods, ranging from 3 to 24 hours.
  • Insulin Pump Connectivity: One limitation of the G7, as of September 2023, is its inability to connect to insulin pumps. The Tandem t:slim connects now, and users of the Omnipod 5 will have compatibility soon.
