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’m willing to bet we can see longevity improvements from better blood sugar control. Not 100% certain but extremely likely, this would include potential heart attack and dementia reduction…
Cardiac surgery, burn units, ICU, neuro come to mind. All have been studied to show mortality and complications improvements with AGC, but unfortunately the commercial technology has not materialized yet.
Metabolic psychiatry is rising, though very slowly. You do "epilepsy keto diet", and may work in bipolar/schizophrenia (need GKI 1-2, it's not keto for weight loss). But you don't need the continuous monitor, normal ketone monitor is fine, because the food list is very narrow.
The continuous monitor should help until you get the hang of the diet, it's a bit hard to maintain, but if it works, worth it.
Ketones have some dieting and weight loss applications, so I guess you could do better real time tracking of how you're digesting carbs and when it's okay to eat? maybe
They are specifically relevant to trying to enter a fasted state.
The presence or absence of ketones in your blood can tell you whether or not (say) that coffee you just drank took you out of the fasted state (that you were in for not eating overnight).
Whether or not you are in a fasted state matters not just for weight loss, but also for things like longevity (when you are in a fasted state your body cleans up dead cells that contribute to things like cancer, whereas in a non-fasted state it leaves them lying around).
Invasive CGMs (Continuous Glucose Monitor) and minimally invasive CGMs exist. It's the non-invasive CGMs which are being worked on because managing an implant or having something always poking through you is a big annoyance+risk compared to wearing a watch, ring, or patch.
The problems for these non-invasive options so far is they either too easily fail to work, are bulky/expensive, give very ballpark accuracies, or some combination thereof.
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.
These are the same CGM technologies (Dexcom = Stelo and Lingo = Libre), just aimed at the over the counter "health and fitness" market.
This is not verified info, but I would assume these are either A) the exact same device, just with different marketing B) "binned" production runs that did not meet the accuracy threshold for clinical/prescribed use, but are otherwise "good enough" for someone looking to healthmaxx.
I t
Looked into the OTC ones and it does seem they’re binned versions. The failure rate appears to be higher too, which is more acceptable in a non life threatening device.
It also probably gives the companies really valuable data.
Does anyone know if something like this is required to be approved by the FDA? Like if someone were to make one for the hobbyist/weight loss market, would that even be legal?
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?
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.
There is a major IP holder in the space who is asserting their ownership, so even if they could solve the technical challenges, they might not be able to come to market.
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.
A few years back, there were a number of startups that essentially resold prescriptions of the ABT/DXCM CGM and provided personalized meal/exercise-response analytics on top. Seems like traction has been tough going, though. Dialing back from "anyone with potential metabolic issues" -- what's a realistic market? Something like high-level athletes and/or bio-hacker enthusiasts are the only folks who seem to care. On the low end, the OTC options are eating away as well.. they are less accurate, but probably solve the use case better for a pre-diabetic "once-a-year/occasional" wear use case.
Talking to ultramarathoners and cyclists, I think lactate is a biomarker that is tracked (POC blood samples) and would be more immediately useful for training/performance. AID might be construed as a form of doping, IMO.
Lactate actually comes for free with blood glucose when you measure it with a chemical sensor, it's just not something that's usually asked for. I definitely think it would be considered a form of doping to use it in competition, but I think recovery is where it would make more impact anyways. You also wouldn't want to use it before a race, as you'd run the risk of reduced pancreatic function.
AGC will find its main application in surgical and inpatient uses, eg in cardiac, neuro, burn, ICU, and people with diabetes in any hospital setting.
I am aware of the "eating wins races" strategy for endurance sports.
Glucose and ketone monitoring seems a natural, more precise extension of that strategy. Isn't the point of carb-cramming to get more glucose into your blood stream, where your muscles can convert that into forward motion?
Yes. But you don't need to monitor glucose levels to do this. Because it's well known you can productively use as much as you could manage to consume (without vomiting). So all the device will ever tell you (if you're in the middle of significant endurance event) is that you need to raise your blood sugar. It'd be no more actionable than a writing 'your blood sugar is low' on your hand with a sharpie.
Monitoring glucose and ketones can help you develop metabolic flexibility and let you grok how easily your body cuts over to ketones. Knowing your personal realtime glucose and ketone levels helps you understand just how much carbs will kick you out of ketosis or keep you in it. Glucose monitoring will help you avoid large crashes that can lead to low energy. Among other things!
My understanding is that essentially all high-level endurance athletes are just maximizing their simple sugar intake at all times (during exercise) and knowing blood glucose/ketone levels wouldn't change anything about that intake, nor would it have any impact on crashes.
As someone who has to deal with type 1 diabetes every day, this is marketing nonsense. No one needs ketones in the sensor - we need high-quality sensors, and Abbott's are only mediocre at best. They are not as bad as Dexcom, which is appalling, but they are still far from the superior quality of Medtronic/MiniMed which measure glucose exceptionally well.
Ketones are rare. They can kill you, but before that happens, your blood sugar usually rises enough for you to realise you may have ketones and start using test strips to measure them. Instead of this marketing gimmick, Abbott should have focused on improving the quality of their glucose sensors which is far more important.
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
A CGM that has ketone levels is quite literally pointless. If you have a CGM in the first place you would know if your sugars were high enough for long enough to get DKA.
Mate they won't understand. People generally are exceptionally ignorant about type 1 diabetes and also eager to fall for marketing gimmicks like this one. They have no idea what type 1 diabetes is.
For anyone who doesn't get it: glucose is checked every five minutes because it changes very often, jumping or falling dangerously. It's a nightmare. Checking glucose is 1000 times more important than ketones which are almost never a problem. If you get accurate glucose readings you are highly unlikely to ever experience ketoacidosis in the first place. Before ketones become a problem, glucose has to stay high for hours. Abbott is pulling this marketing trick instead of improving the quality of their sensors. Libre 2 is absolute crap. Libre 3 is somewhat okay and sometimes even mediocre - which is still a pretty bad situation. Bad glucose sensor is a nightmare and it can kill a person or a child much likely than ketoacidosis. It will actually lead to ketoacidosis by showing incorrect glucose readings. Now I wonder whether they added a ketone sensor as a failsafe for their low quality glucose sensors.
No one asked them to add a ketone sensor as an add-on to their glucose sensor, except maybe their marketing department. People want higher quality glucose sensors that fail less often and are more accurate. Glucose sensors, not ketones!
What areas do you have in mind outside of diabetes management?

The "real" device gives you what it measures as your real highs and lows while the OTC devices won't report high highs or low lows.
I have a Stelo (I was curious and diabetes runs in my family) while my wife has the Dexcom.

Yeah I guess make enough money and then lobby for the benefit of your audience base or for future proscuation
Diabetics would snap up a smart watch which does accurate glucose monitoring in a heartbeat.
Is it a secret? Why not name them?
(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

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

For example, about 20% of that number is because someone is finding out for the first time they have T1D [1].
Insulin costs and monitoring costs are also going to be a pretty big contributing factor. CGMs and finger sticks aren't cheap.
IDK how often it happens that ketoacidosis happens when glucose appears to be fine, I assume it's pretty rare.
