Are these devices (Free Style Libre) safe for contact sports? I wanted to wear one and even got a scrip for one as i am pre-diabetic. I do BJJ 4x a week and am concerned about the device on the arm getting dislodged or broken. I thought about neoprene arm sleeve, etc. Anyone have experience with contact sports and such devices?

When I was doing a lot of sports (though nothing quite as high contact as grappling), I'd put a couple of strips of kinesiology tape over the sensor which helped a lot with keeping them on. You need to put something non adhesive between the back of the sensor and the tape though, to avoid pulling it off when you change the tape.

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 don't think we'll ever have safe CGM that isn't minimally invasive. Proteins are weird and you really need to measure blood, not a picture of blood through skin. We are only recently getting CGMs that don't need frequently recalibrated via a finger stick. I hope someone prove me wrong but it would be quite the leap forward in tech.

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 predia…

Is there a way to get this device without a prescription? I tried phone apps that use the FreeStyle Libre and make it into a CGM (e.g., https://www.levelshealth.com/ ). They're great but also super expensive.

(Merely as I was curious last year about the effect various foods had,) I just ordered all the equipment on Amazon (though, it probably helps that I dated a type I diabetic for many years and have another type I friend that uses the Dexcom and so I knew everything I needed to get).

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…

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. [0] https://en.wikipedia.org/wiki/Barnaby_Jack#Insulin_pumps

On the other hand, those OSS closed loop systems are only possible because of such vulnerabilities that allowed reverse engineering.

Total tangent, but having moved to Germany from the UK, one thing I can’t find is (what in the UK we’d call) granary or seeded bread. The Germans have lots of lovely bread… but even the dark brown stuff is very smooth with (I assume) refined flour and no major seed/grain content. This might explain your blood sugar spike from brown bread?

Have you tried Schwarzbrot?

I'm actually part of a research team working on using a wrist mounted spectrometer to actually measure glucose continuously and non-invasively. Turns out it's a really really hard problem.

Oh exciting! That’s a billion dollar invention if you crack it. Do you mind sharing who the team is? Do they have any literature available?

Rockley Photonics is working on this:

There was a press release last year because they're an Apple partner. I have high hopes but I keep remembering that Theranos had a lot of promise too.

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…

Do you have any information about what happened?

(context: my son is DT1) We learn (in France) that hypoglycemia can lead to unconsciousness, but cannot be fatal as the liver will eventually take over and release glucose to the organism, as it always does for healthy persons. Glucagen injection is the way to get this release to happen fast, but it can be delayed if necessary.

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 have a similar setup, but with the Fitbit Versa 3 connected to Nightscout (https://glancewatchface.com/).

I can imagine this being incredibly useful for parents!
