How to Stop CGM’s from falling off

Diabetic sensors falling off can be super annoying. It can make supplies run out quickly, increase the burden of living with type 1 and can cost a lot!

Here are my top tips for making sure they stay on until they expire!

1. Keep the skin clear

keep area dry to prevent CGM falling off

Before applying your sensor, make sure the area is clean and dry. Do not use any creams, lotions or fake tan before.

Also be aware of getting it wet or exercising right before or after applying the sensor. It can cause the glue to not stick down. I would advise waiting 1 hour before/after applying so the glue can set.

2. Sensor Placement

Learning where to place your sensor will come with experience. When I first started using the FreeStyle Libre I would put it on the side of my arm. I quickly learnt this is a prime spot for it to catch on a door frame. Now I place it further around the back to prevent this from happening.

Placement depends on the type of CGM/FGM you are using, so have an experiment and see what works best for you.

3. Wear extra support when needed

When you are doing activities that makes a sensor falling off more likely you can put another layer over the sensor. This may swimming or going to the beach etc.

Some people like to use big stickers that cover the whole sensor and upper arm, medical tape can also work well.

I personally like to carry a libre band with me so I can put this on quickly and take it off easily (what I’m wearing in the picture to the rightclick here to view on Amazon).

4. Get someone else to apply your suncream

Sun cream can get under sensors very easily, so ask someone else to apply it to the area if possible. This will also ensure the skin is fully covered, preventing sunburns.

5. Be careful in the heat

Intense heat can cause the glue to melt which makes the sensor tug away from the skin. If this happens, move somewhere cool if you can and hold the sensor down until the glue sets and re-sticks.

This happens very quickly in saunas and steam rooms, if you use these keep an eye on your sensor and don’t stay longer than 15 minutes.

*Remember most sensor companies will replace faulty sensors. Contact them to see if you are entitled to a replacement.
