What is Dexcom G7, and how is it Different?

Unlike the old CGMs, which required separate transmitters to be attached to your sensors, the Dexcom G7 is a CGM System that comprises up of an improved sensor that has a built-in transmitter, and a compact handheld G7 reader which, as the data can be sent directly to your phone, is not mandatory. These sensors are much smaller than their predecessors and have a warm-up time of 30-minute only. Each sensor lasts for up to 10 days and at the expiration of sensors, you get a 12-hour grace period.

Sensors have micro pins for detecting your glucose data from interstitial blood, which, if not inserted correctly, may result in inaccuracies or other errors. People with an active lifestyle find it helpful to use CGM stickers, such as CGM Patches for better grip and keeping their sensors intact.

Not only the Dexcom G7 sensor have better features, but its size is also far more compressed than prior generations from Dexcom. Hence, apparently, it’s more practical for many.
