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.. 1: Dexcom G6 or G7 app false low alarm bug. The Dexcom G6 or G7 mobile app shows you the real-time data being collected by your sensor, and it should automatically alert you in case your glucose levels fall unacceptably low. However, there are plenty of reasons why it can also throw a false alarm.
Dexcom in fact disagrees with me on some of my opinions! (1) Never, ever calibrate during a period when bG is RISING, even a little bit. Dexcom readings are much more "late" on rising bG than falling bG. (Calibration during a time of "moderately" falling bG, a fall rate of less than 1 mg/dL per minute, is OK.).

Much of it was taken directly from Dexcom product support documentation/white papers and product specific conversations with Dexcom support staff.. This sensor was working well for a week so I took the.
