One explanation may be that something is pressing on your sensor which can affect your Dexcom G6 readings. Once the pressure is relieved, your Dexcom G6 readings should be closer to your blood glucose meter. Choose a sensor site location that won’t be bumped, pushed, or laid on while sleeping.

For more information on where to insert your sensor, read this FAQ or for more information about what may impact your CGM readings, please review your Dexcom G6 User Guide.
