Applying a sensor for the first time is very exciting. You are so close to seeing what happens inside your body and exploring our programs in the Hello Inside App. However, sometimes the sensor comes off just a few hours or days after application and you were definitely not ready to say goodbye to it. You were just getting started. Well, there can be many reasons for that but we collected some tips for you to make sure your sensor sticks well so you can enjoy the full 14 days of glucose tracking and exploration.
Which CGM sensors does Hello Inside use?
We use the Abbott FreeStyle Libre 2 and Libre 3 (in Germany only) sensors with our Hello Inside App. Each sensor lasts for 14 days. You can easily and quickly apply the sensor to the back of your upper arm. The sensor is water resistant, and you can do sports with it. You can find more information on the sensor in our Help Center.
Especially, if you move a lot, do lots of sports and if it’s hot outside (you sweat a lot), it’s important to ensure that the sensor sticks well on your arm when applying it. We collected some tips for you to make your sensor sticks properly and to prevent it from falling off before the 14 days are over.
4 tips to keep in mind before applying your CGM
1) Don’t eat 2 hours before or after:
2) No swimming or exercise 2 hours after:
3) Use a patch or kinesiology tape:
4) Don’t forget to scan your sensor
This tip only applies to FreeStlye Libre 2 sensors as they need to be scanned to transfer data. Be sure to scan your sensor at least every 8 hours to avoid losing glucose data. For FreeStyle Libre 3 sensors the data transfer is automatic after the initial set up scan.
5 tips for applying your CGM
1) Clean the application area
Place the sensor on a squishy part of your upper arm. You should avoid muscle tissue. You can do a “touch test” before application. Feel different parts of your upper arm and choose a place which feels soft.
2) Choose the right place
Find a soft spot on your upper arm to attach your sensor. You should avoid muscle tissue. You can perform a "pressure test" before use. Feel different parts of your upper arm and choose a spot that feels soft.
3) Make the move test
Place the sensor somewhere that doesn’t impair you when exercising or moving your arm. This way, you can avoid rubbing it off accidentally. You can do a couple of moves (like arm swings) or a typical exercise you do often (e.g.: push-ups, squats or a yoga pose) to see your range of motion and where a sensor could be placed without being in the way.
4) Choose the right side
Unless you sleep on your belly or back you probably have a preferred side you sleep on. We recommend placing the sensor on the arm you usually don’t sleep on. So if you usually sleep on the right side of your body, place the sensor on your left upper arm.
5) Check the edges & the glue
After applying your sensor, ensure the edges of the adhesive stick firmly to your skin. Just lightly press down the edges all around the sensor or draw a couple of circles around the sensor with a small spoon to make sure the adhesive is on the skin.
You’re all set to apply your sensor. Keep these tips in mind when doing so and enjoy your exploration journey!
