CGM Sensor Affected by Posture?

Even though my Dexcom reciever is in my pants or shirt pocket it will sometimes show no readings for an hour or so. I’ve noticed this especially after lunch at work, when I’ve been sitting in my chair for an extended period.



The sensor is on my abdomen and after an hour or so I’ve probably been slouching. The receiver starts picking up readings again after I get up and walk around and move the receiver to another pocket, usually closer to the sensor.



Do you think my posture has something to do with the effectiveness of the sensor or is it something else. such as moving it to a new pocket?



I’m suspecting it’s my posture or some pressure on the sensor because I sometimes see the same phenomenon in the morning when I arise.
