bet marathoners and ultra runners will start using this to improve performance

(don't have a problem with that, but it's predictable)

too bad it's not "wearable" like a watch but that might be coming eventually too since Garmin has a patent on it

(btw Fenix 9 launched today but it's same hardware as Fenix 8 and no glucose feature)

There has been talk, but as one who hangs around those circles I've not heard of anyone actually doing it. But I'm sure someone is. At the same time, what I'm reading is that CGM won't give a non-diabetic any actionable information.

a regulated blood sugar level aids massively in cellular repair, inflammation reduction, and immune response. These are well studied and established. I could absolutely see a top athlete using AID in the future as part of a recovery routine, but I can also understand reluctance to adopt anything new or weird.

I am curious how this will help. During training? During the actual race, the strategy is to eat a much as you can without puking.

> to improve performance

How? Like, what is the mechanism where this is useful?

ijustlovemath•57m ago

Automated glucose control will be the next frontier in so many areas of healthcare. I'm still skeptical that anyone will be able to noninvasively and accurately sense blood sugar, but I'm glad people (especially kids with T1) will have one more tool to help them. I hope they can figure out the reimbursement side to get it into the most hands possible!

I thought this was going to be a non-invasive sugar-level device, but it looks like in fact the innovation here is that a popular CGM line can now do ketones?

ijustlovemath•32m ago

non-invasive continuous blood sugar measurement is mired in patents and technical challenges. Turns out it's really difficult to disambiguate the absorption lines of glucose from other similarly shaped molecules when you're also dealing with untangling skin conductivity, transmissivity, sweat, inflammation etc.

I also think there's no financial incentive from incumbents to develop something like this. Why would abbott develop something that works "forever" if they can milk people buying new sensors every 10~14 days.

Seems to be the case, yeah

Looked after my son who has T1D for now 5 years, checked keytones maybe 20 times. Compared to blood glucose which we check look at every 5 minutes.

Maybe this is more for Type 2 or other diabetes, or for people prone to DKA. Or it is for people with a working pancreas who think looking at their blood sugars (and now keytones) tells them something like soothsayers reading tea leaves

happyopossum•27m ago

Considering that DKA accounts for 160k hospital admissions a year, your lived experience translates poorly to such a flippant dismissal.

DKA is what killed the legendary Dan Kaminsky, who I had the pleasure of meeting at BlackHat many years ago.

What about all the other wearable sensors like

Those ‘only’ measure glucose levels. As the article says, this is the first approved device that monitors both ketone and glucose levels.

No FDA authorization I guess

eej71•11m ago

Nope that was two years ago.

The difference is that these only measure blood sugar, while the new system also measures ketones, of keto diet fame, which are leading indicators of a really dangerous situation called diabetic ketoacidosis. It's treatable with a hospitalized IV insulin drip, but can be avoided if you have some advance notice.

So she was merely ahead of her time.

The use case was never the problem. The problem was that it did not work.

That silly patch idea?
