Dexcom Stelo compression lows

Pressure on the sensor, for example lying on it, can change readings. Relieve the pressure and the numbers should get closer. (Dexcom user guide, p. 63; Stelo (Dexcom))

What the maker says to do

1. Move off the sensor to relieve the pressure.
2. Avoid sensor sites that get bumped, pushed, or that you lie on while sleeping.

Stelo is sold over the counter in the US only. Dexcom says your primary residence and your Stelo account must be in the US.
