For more context for people who don’t know. You can buy CGM devices over the counter from places like Walmart and Amazon. They attach to your body and monitor your blood glucose via a small “thread” that goes into your skin when it’s applied. They typically cost $50 for two weeks. The OTC version has been around for a shorter period of time than the ones that require a prescription, but work the same way. The OTC ones tell you they are not for diagnosing diseases. Or for people who rely on insulin. And Dexcom, the company in the article, is the most prominent vendor for these sorts of things. “A Dexcom” is the “Kleenex” for CGM in the type 2 diabetes world. From what I’ve seen. RFK has been talking about wanting all Americans to use CGM for a long time now. This is part of that. The MAHA people talk about metabolic stuff like it’s the solution to our fucked up food culture in the US. I use a CGM. But I can’t help but be suspicious of RFK. Rumors are that Apple has been dumping money into figuring out how to make the Apple Watch do CGM. They have been chasing it for years.

Apple has some interesting ip acquisitions on this that may see the light of day in a few years, but many of the GCMs use Bluetooth, and the security on them (as well as accuracy of the fucking dexcoms) is atrocious. So I ask you, why would a fascist regime want to encourage trackable wireless devices attached to “the weak.” Hmmmmm

Unfortunately there are very few actual CGM brands available. There are a bunch of different CGMs, but most of them are just relabels of other units, almost all of which are made by either Dexcom or Abbott. Even more unfortunately in my experience they wildly exaggerate the accuracy and lifetime of the units. Most claim an accuracy of +/- 20% which is pathetic for 14 days, but you’re lucky if it maintains even that terrible level of accuracy for half that time. In my case I’m horrendously allergic to the adhesive that Dexcom uses on their units, so I can’t even use half the CGMs on the market, and I gave up on Abbott after their units started to struggle to even make it 48 hours without being off by more than 50 mg/dl.
