Yesterday I checked my blood sugar it was 307- ahh! BUT the weird thing was that my sensor said that i was 124, that is a biggg difference, does that mean its not working? has this ever happened to any of you?
That is good to know! No one ever told me anything about it, but it makes sense. What about for other CGMs?( I use the Medtronic one), not the Dex as was discussed in your previous blog. Is there chemistry based upon the same enzyme interactions? Very helpful info, thank you!
omg I didnt even THINK of that. I had a reading in the middle of the night last night that said I was at 307. I checked my BG meter and it said 169. But, I was sick yesterday and took 2 extra strength Tylenol.
Then this morning my Dex said I was "High" (over 400) and my meter said I was 250. I had taken 2 Tylenol this morning too.
I was just about to change my sensor site. haha. Good thing I read this!
Hi Kristen- Yes, it depends on how long it's been since you calibrated your Dexcom with your meter. I calibrate mine every 5 hours or so. Kind of out of habit, I guess. Also, if you've taken anything with aspirin in it (Thanks Manny!) Or if your Dex is not in an accessible site on your abs. Your fingertip readings will change BG FIRST. So, if you've just ingested a ton of carbs, it might not be running thru your body yet, but it'll show in your fingertips. Also, if your Dex is running short on battery. Or if it's on the final day before you need to change your sensor (Day: 6) Or if you're sleeping on your stomach- it'll interfere with the readings transmitted to your Dex.
I use my Dex as a "trend graph" only. I still trust my body and what it's telling me. If I feel sick but my Dex tells me I'm "fine", then I check w my meter just to be sure.
happens, yeah. Wait one hour after clearing alarm to recalibrate. If you calibrate immediately with such a differnet reading it continues to freak out. So test, treat, wait one hour & recalibrate, should get it back in line
