Pros and Cons of Dexcom G7 – CGM Device

Pros and Cons of Dexcom G7

This is a continuous glucose monitoring device, usually known as a CGM. This comes with a sensor, and a monitor (or you can also choose to see results on your mobile phone).

CGM Sensor is a small device that can be worn in a few different places, the most famous ones of which are back of the upper arm and abdomen (2 inches from belly button).

CGM Monitors is a discreet and compact device used to see your real-time glucose readings and trends. Some of the readers also have the option of taking notes and alarms as well.

What is Dexcom G7?

Dexcom is known for its innovation in the CGM world and Dexcom G7 is a huge milestone covered. Not only it’s a discreet and tiny CGM but its connectivity with smart watches has astonished the world. This means you can now see your glucose results right on your wrist. You can see a list of compatible watches here ‘’ What smart watches are compatible with Dexcom g7? And how to connect?’’

Plus, previous Dexcom CGM models like G6 used to have separate transmitters which was causing a bit of hassle. However, with Dexcom G7, there is no separate transmitter required.

Pros of Dexcom G7

  • The Dexcom G7 is almost half the size of Dexcom G6.
  • Less warm up time – approx. 30 minutes only.
  • There is also a 12-hour grace period included with the new G7 Dexcom sensor.
  • Compatible with both, iOS and Android smartphones.
  • It is easily inserted with a one button applicator.

Cons of Dexcom G7

  • The Dexcom G7 sensor is affected by pressure and movement at night.
  • The Dexcom G7 is affected by high levels of vitamin C, resulting in imprecise glucose readings.
  • It may lose Bluetooth data signals sometimes.
  • It may cause bleeding, pain, infection, swelling, itching, or skin irritation.
  • It is smaller than the Dexcom G6, but still bigger than Freestyle Libre 3.
  • CGM patches might be required as the adhesiveness of the sensor may run out before 10 days.


To sum up the pros and cons of Dexcom G7, I would say the addition of readings on the wrist, the grace period, the shorter warm-up time, and the new sensor insertion are amazing. And the errors people have experienced can definitely be resolved by Dexcom.
