That sounds like a life-threatening bug.
- ferringb 3y agoMost sensors do this. You're assuming the sensor is always accurate- they aren't. Roll over onto the sensor while sleeping and you shove the glucose oxidase strip deeper into the body resulting in a change in readings, for example. Strictly speaking, you're not supposed to make treatment decisions based on the CGM data. For dexcom sensors, certain apps can pull the raw values and bypass this. For libre- at least the libre3- I've seen it backfill the data in certain cases where it seems to realize that it's not a bad reading, your BG is just going through a fast swing.
