I started a new sensor on Friday night. It hasn’t been terribly accurate, but it’s the only one I have (getting new ones in a few days), so I kept it in, because it’s better than nothing. It has, though, normally been fairly decent.
However, this morning, at around 5:30 or so, I wake up, and it tells me I’m 50. I think, I really don’t feel low. So I test my sugars on my monitor, and I’m 288. I wash my hands (just in case), and I’m 293. I enter these in and I give myself insulin, so when I test on my meter a little later, I’m 235 or something, but my Dex says I’m 326 and going up. (Has anyone ever had this happen? Any reasons why it might happen?)
At this point, I stop the sensor and restart it. My thinking for this is that it will wipe out any inaccuracies I might have caused by entering in bad blood sugars or calibrating at a bad time. (I would have just put a new sensor in, but I won’t get one for a few more days.) I also called up Dexcom, and they told me I should just wait and see how it goes. They also told me that stopping the sensor and restarting it won’t do any good.
However, since I restarted the sensor, it’s actually been working fairly well. (Obviously, I waited until my sugars were steady before entering bgs.) For the first few hours, it kept telling me I was going up, when my meter told me I was fine. But, since then, it’s been somewhat accurate.
Sorry, this has been kind of rambling, but my question is: Has anyone stopped and restarted a sensor and has that helped? Tech support said it wouldn’t, but it seems to have. It seems logical that, if I’ve entered in too many sugars or I calibrated when I was going up/down and didn’t realize it, stopping and restarting would clear out all the weird sugars it remembers. Does it?
