Comment on Innovative Saliva-Based Glucose Sensor to Revolutionize Diabetes Monitoring
mvirts@lemmy.world 9 months agoNot so, I literally haven’t needed to do a fingerstick since I got the g6. They come calibrated and as long as you can go 3 hrs between sensors without testing you’re good to go. Maybe for someone with a different activity level this would change, but for some people no fingersticks is a reality.

I’ve had one for about 3 1/2 years and that’s not my experience, unfortunately. Some of the sensors are right on from the start and stay that way… maybe 30% of them. Some are off when they start and take 1-2 days to start reading correctly. In the meantime, it might say I’m 140 when my meters say 110, or 110 when my meters say 140, or at worst, Dexcom says 90 when I am obviously low and I check and it’s 65. Some sensors are just whacked out and unpredictable, like I’ll be hanging at 100 and it shows a quick drop to 90, 75, 65, and I’m uh, what? And check with a meter and it’s 110. Also there’s the 2 hours when I don’t have a sensor when I change them. So, sometimes I go weeks without a fingerstick, but now and then I use just as many as I would without a sensor because I can’t entirely trust it.

Hey friend. Pay attention to where you’re inserting it, when I roll onto mine in bed, the values drop precipitously because you’re squeezing out and preventing flow of subcutaneous fluids that the dexcom is specifically sensing.
Also of note, the dexcom doesn’t sense your blood sugar directly, the sub-q fluids are a slightly delayed version of your blood glucose. Measurements between the two are almost guaranteed if you’re a living being. (Which I presume you are right? 😋)

I’m aware of the pressure sensitivity thing causing a false low, and also how it works on interstitial fluid.

Honestly I don’t calibrate almost ever, so I should really clarify that my symptoms match my sensor glucose most of the time. I do see the occasional too-fast-to-believe change, but that’s usually at the end of a session and either corrects itself or is too small of a change to affect my decision making. I’ve been on a cgm for about a year, but have been diabetic for 28 and I must admit that my glucose monitoring before the cgm was horrible, so accurate or not for me it’s a major improvement. using tandem control IQ closed loop is what has made the biggest impact on my a1c ever.
