First, let me say that I'm not diabetic, but I have a question. I keep seeing commercials for these monitoring devices that work through a phone app, like Dexcom, etc.. The claim seems to be that by using them, instead of finger sticks to check glucose levels, that A1C levels drop automatically? How does that work exactly? They literally seem to make that claim. "Since I stopped sticking my finger and using Dexcom (or whatever), my A1C has dropped X points!" And to be honest, I don't even know what A1C is, but apparently it's best if it's below 7?
