What happens if my sensor insertion causes bleeding?
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. If the sensor is inserted too deep into the body, it may also bleed. Ensure you are not using excess pressure when inserting with the applicator.
Proper insertion technique is important to prevent bleeding. When pressing the button, the sensor should be resting superficially on the surface of your skin.
