How can I avoid skin irritation caused by the CGM sensor adhesive?
Use these considerations to help mitigate Dexcom CGM skin irritation or adhesive allergy for those with sensitive skin.
Why is my trend arrow missing?
When there is no arrow, it means more glucose readings are needed to establish your trend.
What do I do when I get the Sensor Failed message?
This means that your sensor is no longer working. Remove the failed sensor and replace with a new one.
What do the Question Marks (???) mean?
The question marks mean that the transmitter does not understand the sensor readings for the moment. You will want to wait a minimum of 3 hours for them to clear. If they do not clear within that time frame, please contact Dexcom Technical Support at 1-844-82-1810 (Option 3).
