I have had my Dexcom for only one day and several hours. I went to my endocrinologist for help with putting the first sensor in and instructions etc.- it's in my right middle abdomen area.
I've had several readings which have been from 40- 59 points different than the blood glucose finger sticks as well as incorrect. I can tell when they are wrong on Dexcom right away- the lows and higher readings are all wrong. I'm spending too much time calibrating Dexie.
The last one just said I was 49 and gave me the below 50 alarm, the finger stick was 109.
Should I try another site? I'm not sure what to do. I also think something is wrong with my receiver as it doesn't always seem to vibrate/beep now with warnings all of which have been low.
That is a large part of why I wanted cgm- I have been having low lows and I'm worried about this when I'm sleeping, but none of Dexies readings so far have been correct for that. The other part is to see what is happening all of the time which I can't possibly do with finger sticks alone.
Will this get better? Am I doing something wrong? I'm wondering if after another try with a different sensor/location I should send this back and wait for the new and improved model?
