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 to the transmitter housing, this could form a barrier between the contact points. If that happens:
1. Remove the sensor and insert a new one.
2. 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 inserting your sensor.
Seek medical attention if you feel medical intervention is necessary.
How can I try to avoid bleeding?
Proper insertion technique is important to prevent bleeding. When pressing the button, the applicator should be resting lightly on the surface of your skin. Don’t press downward when applying the sensor. The applicator doesn’t require downward pressure. Use your hand to steady the applicator when pressing the orange button.
