What happens if my sensor insertion causes bleeding?
In order for the Dexcom CGM 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 can cause 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. For more information on how to insert your Dexcom CGM sensor, visit these FAQs based on the Dexcom CGM system you are using.
It may not be necessary to remove your sensor, but if you experience bleeding, please contact technical support for assistance:
