Freestyle Libre II and sleeping.

Hi @LovingLindsay1 I always sleep on my right, so I place my Libre on my left arm all the time. I make sure to change the position each time I put on a new one. It usually doesn’t harm the Libre to lie on it, but it may feel uncomfortable. Lying on it can risk ‘compression lows’, false lows caused by squashing it.

I always sleep on my side and I was just worried about using a Libra 2 sensor on the back of my arm. For that reason I decided to get a Dexcom One+ CGM instead. The Dexcom can be positioned on the abdomen or on the back of the arm.

I sleep on my right have my sensor on my chest at the mo no issues

I alternate arms and sleep on both sides at least when I go to sleep, so I stick either my arm, or a spare pillow (a rolled up towel might work too) under my elbow and rest my shoulder on my main pillow to try to avoid compression lows, seems to work, though that could be because I usually end up sleeping on my back!

I am in awe of people who sleep in one position. I am a wriggler who sleeps on both sides.
My sensor is usually on my arm. I alter sensor arms every two weeks. This causes no problems.
However, i am aware of the risk of compression lows - false low readings from CGMs where pressure applied on the sensor limits flow of interstitial fluid to the filament causing the sensor to report a false reading and potentially alarm. Therefore, I position my sensor high on my arm close to my arm pit as this is an area which I rarely lie on.
In short, there is nothing wrong with putting your sensor on the arm on the side you usually sleep. However, take care not to apply direct pressure on the sensor.

My hubby thinks I’m weird! I barely move when I sleep never mind turn over!

I usually put it on my left. Occasionally I get the classic compression type low recorded ( a very sharp but small V) but only in thr first couple of days. After that it seems to know, or maybe I adapt to it!!
Better to have it on than not imho

I alternate arms and toss and turn most nights. Have had the very odd compression low. Always cover my sensors anyway so I don’t worry about them coming off. A bit tricky for you @loving Lindsey1 unless you are with someone who could put it on for you. I can see and still have my husband apply the cover as they are a pain to do.
