I was looking into this the other week, I couldn't find a CGM supplier in the US that would sell dtc. I don't need it for any medical reasons. Im just interested in the data. Anyone know of a supplier?

Veri/Levels as others mentioned if you dont mind paying $$ and want the fancy data viz and UI ...or just sign up for a free (15$ really) trial of the freestyle libre here: https://www.freestyle.abbott/us-en/myfreestyle.html . It'll ask you if you're a diabetic and you just click yes

Friend of my wife, type 1, just 2 weeks ago died in his sleep from mismanaged blood sugar. He was only 37 and was otherwise very healthy - it was shocking, I never knew it was so dangerous and that mis measuring or forgetting before going to bed could have such dire consequences. I though it was like sleeping with your contacts in. This is a gap this tech could close, I hope it’s widely available soon - hopefully an…

I'm sorry for your friend. Truth is even a lot of doctors don't appreciate how difficult controlling type 1 diabetes can be. Having lived with it for over 20 years I'm still shocked at how ill-prepared I was once I came home from the hospital.

CGMs can make all the difference in the world, and I hope they continue to get better.

Rockley Photonics is partnered with Apple and medical device makers, developing a spectrophotometer on a chip for devices like the Apple Watch and other medical wristbands. Their sensors can measure multiple biomarkers in the blood in addition to glucose, like alcohol, hydration, core body temperature, lactate. They are presenting at the Baird investment conference Monday morning. https://www.yahoo.com/now/rockley-ph…

there are several r&d companies like rockley trying to bring contactless optical measurement to market, e.g. https://www.diamontech.de/home Most are based on quantum cascade lasers. go science :-)

Many people are controlling their insulin pumps via phone and watch apps: https://github.com/LoopKit/Loop

The app tries to predict blood glucose in the future (drawing on CGM, food intake, lots of parameters and other data) and based on that either automatically injects insulin, or asks the user to confirm.

People need to compile the app themselves because the liability in the case of adverse effects is insanely high.

It’s a highly driven community. I’ve seldom seen such a useful and well supported application of modern tech.

Reminds me of Barnaby Jack [0] who in 2011/2012 "demonstrated that he could wirelessly hack the insulin pump from a distance of up to 90 metres using the high-gain antenna". That was based on the hardware and not even all kinds of smart cloud-connected apps having bugs to exploit.

Where does one buy these glucose monitors ? Do you need to get it prescribed by doctors ? Or can healthy people get one too ?

You do need a prescription in the US.

If you just want it for a month to check out your blood sugar, you can ask your doctor to prescribe you a one-month trial pack. (They're technically for diabetes screening to see if you're diabetic/prediabetic).

If you want them for a longer period of time, and you don't care about insurance covering the thing, you can straight up buy them from a startup like Levels. I think they have a doctor prescribe one for you via video call, but it's more just to explain how to use the thing, and it's unlikely to be covered under insurance if you're not diabetic.

What ever happened to that glucose monitoring contact lens that google/verily was working on?

It's a really hard problem. There are perhaps a dozen experimental noninvasive methods to get a rough approximation of glucose levels, but none that work consistently enough and accurately enough to make insulin dosing decisions. For that you need fingerpricks or a subcutaneous CGM.

I had some ideas on how unreliable all nutrition research is but nothing prepared for the flood of bad advice once I was diagnosed with diabetes T2. I now trust one thing and one thing alone and that's my Dexcom G6. If it shows a spike eating the same meal twice , that meal is off the list. That easy. I deleted normal flour, potatoes and rice from my life and per three month blood checks I do not even count as prediabetic now. (Of course, the system is still very much not okay: I ate a slice of brown bread in Vienna thinking it might be okay, it wasn't okay. Luckily, I am not getting seizures from it, phew!)

It must've been really, really hard navigating this minefield without it. Speaking of minefields, grocery stores are one. There's sugar in everything the sugar industry made Americans into sugar addicts, it's absolutely shocking and horrifying just how much of it is in bloody everything.

As wonderful a medical innovation dexcom is, their website is absolutely terrible. I am Canadian but I run an AT&T SIM because it's cheaper -- in 2018, AT&T removed North American roaming restrictions, they know and they are fine with us using it 100% in Canada. Now, the Dexcom app uses the gsm.sim.operator.iso-country Android system property to determine which country you are in. If it finds US then it registers you to https://uam1.dexcom.com/ otherwise https://uam2.dexcom.com/. There's absolutely no way to user select this. However, the browser uses IP geolocation... because of course it does. So you can't log into your own account unless you figure the above uam discrepancy out and manually go to the correct one. And for Canadians there is a store account which is neither of the above. It's an independent third. Because of course it is. There's nothing on the dexcom website or app which would mention any of this and their tech support won't say either. It's been a nightmare trying to figure it out.

My son does something similar. In Vietnam, only the Freestyle Libre 1 is available, so we got the aftermarket MiaoMiao transmitter for it. The transmitter talks to an iPhone running xDripForiOS ( https://github.com/JohanDegraeve/xdripswift ) which, in turn, pushes the CGM data to nightscout ( https://nightscout.github.io ). We can then follow that data on nightscout using xdrip on our own phones. It's been a real lif…

I HATE the Freestyle Libre. The concept of continuous glucose monitoring is life saving, but this particular product is very very bad. The hardware design is awful. I've received 9 of them and 5 have broken before their expiration date, for a variety of reasons. Two of them broke immediately at first application.

Glucose monitors in general are expensive ($100+ retail) products that are meant to be disposable every two weeks, which itself is insane. I understand the design constraints that the Libre is under, and they are onerous, but they just have to make a more reliable product.
