It's very exciting to attach a sensor for the first time. You're so close to seeing what's happening in your body and exploring our programs in the Hello Inside app. However, sometimes the sensor comes off just a few hours or days after attaching it, and you definitely weren't ready to say goodbye. You've just started, after all. There can be many reasons for this, but we've compiled some tips to ensure your sensor stays in place and you can enjoy the full 14 days of tracking and exploration.
Which CGM sensors does Hello Inside use?
We use an Abbott FreeStyle Libre 2 sensor and Libre 3 sensor (only in Germany) with our Hello Inside app. Each of these sensors lasts for 14 days. You can easily and quickly attach the sensor to the back of your upper arm. The sensor is waterproof and can be worn while exercising. You can find more information about the sensor in our Help Center .
Especially if you're active, exercise a lot, and it's hot outside (you sweat a lot), it's important that the sensor adheres well to your arm after application. We've put together some tips to help your sensor adhere better and prevent it from falling off before the 14-day period is up.
4 tips to consider before attaching your CGM
1) Do not eat anything for 2 hours before application:
2) Do not swim for hours after application:
3) Use a plaster, patch or physio tape
4) Don’t forget to scan the sensor regularly
This tip only applies to FreeStyle Libre 2 sensors, as they require scanning to transfer data. Make sure to scan your sensor at least every 8 hours to avoid losing glucose data. For FreeStyle Libre 3 sensors, data transfer occurs automatically after the initial setup scan.
5 tips for attaching your CGM
1) Clean your skin where you want to place the sensor
Wash the area on your upper arm where you want to attach the sensor. Use a regular soap (non-greasy) to remove any oil and dead skin. After washing off the soap, let the area of your arm dry completely.
2) Choose the right place
Find a soft spot on your upper arm to attach your sensor. 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) Take the movement test
Place the sensor somewhere that won't interfere with your movement while exercising or moving your arm. This will help prevent accidentally sliding it off. You can take a few steps (with arm swings) or do a favorite exercise (such as push-ups, squats, or a yoga pose) to see how wide your range of motion is and where a sensor can be placed without getting in the way.
4) Choose a side
If you don't sleep on your stomach or back, you probably have a preferred sleeping side. We recommend placing the sensor on the arm you don't normally sleep on. So, if you normally 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, make sure the edges of the sticker stick firmly to your skin. Simply press it around the sensor or use a small spoon to make a few circles around the sensor to press down the edges.
Now you're ready to install your sensor. Keep these tips in mind and have fun on your journey of discovery!
