What happens if my sensor insertion causes bleeding?
Should the sensor be replaced if bleeding occurs?
It may not be necessary to remove your sensor, but if you experience bleeding and the bleeding spreads through the patch, please follow the below:
- Remove the sensor and insert a new one at a different location. For guidance on inserting a new sensor, please consult
- Submit a Product Support Request to report the issue.
Why is there blood around the sensor site?
For the insertion needle to reach the interstitial fluid (where it measures the glucose), it must penetrate the dermis layer of the skin, which has blood vessels scattered throughout. Penetrating the blood vessels can cause bleeding. Inserting the sensor too deeply into the body, can also cause bleeding. Be sure you aren’t using excess pressure when applying your sensor.
Seek medical attention if you feel medical intervention is necessary.
