Comment on Innovative Saliva-Based Glucose Sensor to Revolutionize Diabetes Monitoring
RubberElectrons@lemmy.world 1 year agoHey 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.
