What do I do if I'm bleeding after sensor application?

It’s not uncommon to see a small amount of bleeding right after inserting your CGM sensor. This can happen if a tiny blood vessel is nicked during application, and it usually isn’t serious.

Here’s what to do

  • Stay calm and check the site. A small drop of blood or mild redness is normal.

  • Gently clean the area. Use a clean tissue or gauze to absorb any blood. Avoid pressing too hard on the sensor.

  • Monitor for ongoing bleeding or discomfort.

    • If the bleeding stops quickly and your sensor is reading normally, you can continue using it.

    • If bleeding continues, causes pain, or interferes with readings, remove the sensor and apply light pressure with a clean tissue until it stops.

  • Contact Nico Support. Let us know at [email protected] if you had to remove your sensor or if you’re unsure whether it’s working correctly.

💡 Tip:
To reduce the chance of bleeding next time, choose a site with a bit more fatty tissue (like the back of the upper arm), avoid veins or visible blood vessels, and press the sensor gently but firmly during application.
