I’ve had the same problem. I’m fortunate that I can still feel when BGL is low. When I start feeling strange I will perform blood draw to ascertain my BGL then calibrate my Dexcom. I also had the same problem with the Libre2. The thing that I noticed about drastically differing readings between CGM and BGM is insertion site of CGM. If I don’t insert CGM in the best spot. I get wildly erratic results.

Hi, I’m using a G7 now. The whole time I used my G6 I used my I phone to check my numbers. I didn’t want to use a transmitter. I finally did . It has been life changing. I would say my numbers are within 10 points. I still do finger prick checks before bed and when I’m going somewhere that I don’t want to think about my diabetes the whole time. I know it’s always there but after 48 years there are times when I just don’t want to think about it constantly. It’s always in the back of my mind .

I use the Libre2. The downside to this model is that when it alarms low or high, you check, and dose, it doesn't recheck and alarm again. So, if you get a low and under treat or it doesn't come up enough, the Libre2 will NOT alarm.

If i didnt calibrate my dexcom when i out my pod on yes id some times get wild readings as well.. and when my dexcom says i have a low ill double check doing a finger pole and calibrate it if im going threw a actual low…

That is good to know! I tried the libre briefly. Maybe need to give it another shot! Thank you!
