How to insert your Dexcom G7 sensor

Dexcom G7 sensors may be inserted on the back of the upper arm (indicated for users ages 2 years and older) or the upper buttocks (ages 2-6 years old).

Press the applicator more firmly against your skin before pushing the button. You can’t press the applicator button until you push the applicator so firmly against your skin that the clear safety guard pushes in.

In order for the Dexcom G6 insertion needle to reach the interstitial fluid, it must penetrate the dermis layer of the skin, which has blood vessels scattered throughout. Penetration of these blood vessels causes bleeding if the needle pierces them.
