I don’t know why it’s so rarely mentioned but everyone who uses a CGM should know about compression lows. It’s a false low that occurs when you are leaning on your CGM sensor. It happens most frequently overnight, if you wear it on the back of your arm as instructed. You turn in your sleep and bam, the weight of your body is pressing on the sensor on your arm. The picture above is a clear demonstration how I must have rolled onto my CGM last night while sleeping.
I wrote about this previously as well, but thought it worth repeating.
