Dexcom G6 Vs G7: Features, Benefits, and Price

The Dexcom G6 (clinically proven to lower A1 levels) is an older CGM sensor with a warm-up time of 2 hours, although a sleek one, a separate transmitter attached to the sensor, lasts up to 10 days, has an overall MARD of 9%, a bit bigger than the Dexcom G7, but highly trusted by a huge customer base. In comparison, the new Dexcom G7 is 60% smaller in size, has a transmitter installed within the sensor, has a 30-minute warm-up time, has an overall MARD of 8.2% (in adults), lasts up to 10 days and 12 hours grace period after expiration, however, many CGM users still want to go back to Dexcom G6 (based on research). Before diving into the Dexcom G6 vs G7 topic, here is a brief overview for people with little or no knowledge of CGMs and Dexcom.

Introduction to CGM

Continuous Glucose Monitoring, commonly known as CGM primarily focuses on providing continuous blood sugar levels without the need for fingerpricks. CGM systems consist of a small sensor placed under the skin, a transmitter (for sending signals to the monitoring device), in the latest CGM devices, this transmitter is installed within the sensor, and a software platform that displays the data and provides insights and alerts.

Conversely, since the BGMs (blood glucose meters) are known to provide gold-class blood sugar readings, in case you notice CGM readings going too off from your actual sugar level, a fingerstick test is recommended.

Dexcom CGM devices a brief history

The company was founded in 1999 with the development of a prototype CGM system. In 2006, Dexcom received FDA approval for the first version of its CGM device, designed for people with type 1 diabetes also proved that Dexcom Is Best For Type 2 Diabetes . This device was a significant step forward in diabetes management, as it allowed for continuous monitoring of glucose levels, eliminating the need for frequent fingerstick tests.

In the debate of Dexcom G6 vs G7, considering G7 user reviews, we cannot unequivocally say which one is the winner, however, we can look at the facts and figures of each one. Following is a comprehensive guide to Dexcom G6 vs G7.

4. Dexcom G6 has a separate transmitter with a battery life of 3 months (transmitter and sensor combined size is provided above).
5. Since G6 works with the AID (automatic insulin delivery) systems, the insulin pump should be worn on the other side of the belly button, with the same 2-inch gap. And in case you wear your sensor on the back of your upper arm, it’s advised to wear your insulin pump on the same side abdomen area, e.g.; sensor on right arm and AID pump on the right side of your abdomen.
