FDA stands against using smartwatches to monitor blood glucose
- advisedwang 3y agoThe agency that approves medical devices warns people with serious medical conditions that using devices that haven't passed their standards is a risk. What a shocker. As the article says, tech companies have been able to get FDA approval for the ECGs on smart watches. Tech companies should do the same for any other medical features they want to sell. I am glad to have stringent standards that are upheld and enforced.
- bluGill 3y agoApproved for what? There is a difference between approved for people with and people without diabetes. If you have diabetes you may want this, but if it isn't very accurate it isn't going to do what you want. If you don't have diabetes though this could be a useful thing sitting on your watch, ready to give an alarm that you need to see a doctor because things are looking bad - people often go diagnosed with mild diabetes for a long time (depending on when their next physical is) and starting treatment for those people sooner can improve long term quality of life. Or if you do have diabetes maybe this can sometimes say do an extra blood sugar test at a time when normally you wouldn't (so long as there are not too many false positives)
- lokar 3y agoIt would be useful and probably safe for a diabetic that is not using insulin. Even pre diabetics, just understand how your blood sugar reacts to various foods and activities is really helpful for people trying to manage the disease.
- FireBeyond 3y agoIf it's not accurate, it's not going to be helpful. I'm a paramedic, and for both IDDM and NIDDM patients, watching those numbers, etc., and experimenting, or "chasing the numbers" often leads to more problems than not. The issue for those patients is that hypoglycemic states are acutely problematic in a short time frame AND lead to decreased alertness, impaired judgment and decision making that can make all these things easily cascade. And when the numbers are off? It's very dicy. It's not just akin to monitoring your life metrics.
- salad-tycoon 3y agoFor everyone else, DM = diabetes mellitus and ID and NID = insulin dependent and non insulin dependent, as best as I can tell. Insulin dependent patients could be considered to have severe diabetes or type 1 (autoimmune/“kid” diabetes). In a nut shell. I think even something that is directionally correct could be useful for “pre diabetes “ or non diabetics. A little color coded read out instead of numbers and a general trend may help to keep the numbers at the forefront of your mind. IMO, the susceptible population that I try so hard to get them to start thinking about changing lifestyle just tend to not think about how it is affecting their health and they prefer to wait until they have “full on diabetes” requiring medication. It’s like watching a car crash in slow motion, maybe a green, yellow, red color gradient would help.
- FireBeyond 3y agoYou make a good point here, and yes IDDM -insulin-dependent (Type 1), NIDDM (Type 2), as you say (although for clarity - it is fairly uncommon, but possible to get adult-onset IDDM). If you were wanting to capture trends in pre-diabetics and maybe are looking at ranges, as you said, that could be a useful tool, definitely. "Lifestyle, not (directly) health". Hah, next step, watches that take your A1C blood labs (simplifying, but often used to get a good picture of average BGL over the last three months or so).
- lokar 3y agoThe A1C helps, but there are a lot of people who for whatever reason are just not great at taking care of themselves. They don’t do any more reading/research after the Dr explains it to them, they won’t/can’t track carbs and won’t use test stops. They are really disconnected from how their body reacts to food.
- renewiltord 3y agoTech companies are doing that. It's legacy health companies that have been trying to sell glucose monitoring watches (Masimo, etc.). Apple is not marketing their device as that because their tech is not yet ready. As usual you can count on modern tech companies to be better for everyone. Good for Apple.
- FireBeyond 3y agoWhat?? Apple fans are still bitter at Masimo, evidently. Masimo doesn't sell a glucose monitoring watch[1]. And is not trying to. The continuous health devices they do sell ARE FDA-cleared, because Masimo makes 99%+ of their revenue from selling accurate medical devices. That would be, to use a crude analogy, dangling your private parts within snapping distance of a crocodile. Your whole statement is just inaccurate and derogatory. The W1 watch doesn't do glucometry. It does heart rate and oximetry, with FDA clearance. The upcoming Freedom watch will also do hydration, pulse rate variability, respiration. And will do all of those with FDA clearance. And not glucometry. Your whole stance is not grounded in reality.
- renewiltord 3y agoIf you want to carry water for a predatory corporation so be it. There's a reason your comment sounds like an ad.
- FireBeyond 3y agoHah. I have an Apple Watch, basically everything Appple has released except the AVP. Pro Display, cheesegrater Pro, Studio. And you can verify that from my comment history way way back. But that doesn't mean Apple wasn't predatory here. What they did with Masimo was straight up "brain-rape" (from Silicon Valley). The $7B Masimo was "predatory" to poor $3T Apple? Hah, laughable. And to top it off, I provided factual rebuttals to your inaccurate and false assertions. So you come back with what? An ad hom that basically accuses me of being astro-turf for "legacy healthcare"? Fuck outta here.

- FireBeyond 3y ago> As the article says, tech companies have been able to get FDA approval for the ECGs on smart watches. Tech companies should do the same for any other medical features they want to sell. The issue here is that the FDA has doubts that any of these devices, as they are currently, and also with some significant physiological challenges (think Theranos "this may just not be possible"), are able to do NIBGL accurately, not that "hey, just make sure you get approval, okay?" (NIBGL - non-invasive blood glucose level)
- advisedwang 3y agoThat's just 9to5Mac's editorializing. The actual FDA article [1] reads to me like "guys' heads up that none of these are approved". I see nothing to suggest the FDA means "we will never approve one" or "we doubt the underlying technology can ever work". [1] https://www.fda.gov/medical-devices/safety-communications/do-not-use-smartwatches-or-smart-rings-measure-blood-glucose-levels-fda-safety-communication https://www.fda.gov/medical-devices/safety-communications/do...
- JoeAltmaier 3y agoBlood glucose is hard. Witness Theranos' attempt to do blook analysis without sufficient samples. It apparently can be done from surface contact, with a special patch that measure interstitial epidermal fluid. Do these watches have that?
- stop50 3y agoNo, they want to use light refraction to measure the glucose level.
- Beijinger 3y ago"with a special patch that measure interstitial epidermal fluid." Yes. Dexcom and Senseonics (Eversense) "It apparently can be done from surface contact" It can also be done without pircing the skin. https://quantune.com/ https://quantune.com/ But more complex than Apple thought.
- veidr 3y agoWhat's the TL;DR on that Quantune device? Does it achieve a new level of noninvasive accuracy? (I did visit the website but there is no information (possibly because I'm in Japan which has regulations around public disclosure of information about medical devices that haven't been approved — which is enough of a hassle that sometimes companies just basically show a blank page).)
- Beijinger 3y ago"What's the TL;DR on that Quantune device?" Interesting concept. QCL with photoacoustic detection. "Does it achieve a new level of noninvasive accuracy?" I think so.
- m463 3y agoI'm glad they are holding their ground. Also, I remember reading "the glucose revolution" and I found it interesting that blood glucose is only part of the picture. We currently don't measure fructose level, and that might have effects separate from blood glucose levels. Hopefully folks will go back to the drawing board and either lower the cost of the other continuous measuring devices, or move current tech onwards to acceptable accuracy.
- deleted 3y ago[deleted]
- doormatt 3y ago>We currently don't measure fructose level Apologies, but I'm unsure if you're saying that no devices measure fructose level, or just the watch doesn't measure fructose level.
- m463 3y agoas far as I know no continuous measuring device can measure your blood fructose level. It was mentioned in the book, saying that different kinds of foods might spike your blood glucose level in a similar fashion, yet behind the scenes blood fructose could be wildly different, with a different body reaction.
- salad-tycoon 3y agoFor anyone interested, other useful measurement are a fasting glucose and fasting insulin to calculate a homa-ir (insulin resistance). I personally think everyone , non diabetc, should get one. Not that expensive to buy it yourself at a direct lab consumer purchasing website (USA).
- spandrew 3y agoThe title is more alarming than the substance of the article. Apple is investing in a novel technology that may be able to measure technology using light waves, but the article says it's still in early stages and there's no rush to market with it. Given Apple's history with ECG and other Apple Watch, FDA approved tech there's no nefarious scheme to deliver anything that doesn't pass approvals.
- healsdata 3y agoHonestly, the author of the article is purposefully creating controversy where there is none or ignorant of how the FDA works. The FDA isn't "against such technology" -- they just haven't approved any yet.
- TeeMassive 3y agoImagine we could have a near real time effect of what we eat and then we discover that high fructose products are really really bad. Also imagine that the corporations that produce those products are the worse when it comes to corruption through lobbying.
- qup 3y agoI don't know what really really bad means to you, but we can look around and see people who have eaten fructose their whole lives to no obvious effect. Almost every person I see. So it's not going to meet my personal definition of really really bad. It's already clear and well known that it's bad.
- grecy 3y agoCancer rates will soon be over 50%, and obesity and heart disease have never been higher.
- candiddevmike 3y ago50% of what? Have never been higher per what, a specific age group?
- grecy 3y agoMore than 50% of all people will have cancer in their life.
- hombre_fatal 3y agoAnd that’s due to a magically bad meme ingredient rather than the explosion of calorie dense foods and norms in the food supply?
- novok 3y agoAverage calories consumed peaked in the early 2000s, we eat less calories and exercise more since that time period but obesity rates are up by at least +%20. It's not the calorie counts.
- siliconc0w 3y agoAs much as I think something like this would be a huge benefit, we might need more regulation for these bio-monitoring devices that all seem pretty unreliable in aggregate. In my experience sleep trackers, body fat % scales, calorie trackers, even heart rate meters are 'okay' but have all given ratings that were so bad that I just can trust them. A tracked yes or no question like, "Do I feel like I got good sleep last night?" seems way better than a sleeptracker that can basically only be relied on to tell if I'm in the bed or not. There should be some requirement that you study and publish the correlation of your device to the current medical gold standard for a reasonable sized population. So a sleep-lab sleep score vs a mattress or fitbit tracked sleep score. Or a body-scale fat% compared to a hydrostatic weighing.
- jimrandomh 3y agoTypical usage of blood glucose monitoring (by diabetics) is simultaneously safety critical, and only borderline good enough accuracy. There's a standard metric for accuracy here, MARD (mean absolute relative difference). There is a long history of companies promoting themselves to investors as having working noninvasive glucose monitoring technology, which, if you look at the actual accuracy scores, is only moderately correlated with glucose, nowhere close to the accuracy required. If Apple ships a noninvasive glucose monitor with an MARD of 20, the primary effect will be to set a trap for the stupid: diabetics will attempt to use it to save money, since it will be much cheaper than using real CGMs (which are consumable), and people who try to do this will die.
- nosefurhairdo 3y agoAlternatively, you allow this technology to be sold as a clearly labeled "not accurate enough for treatment of diabetes", and the profit allows more investment in the tech so that one day everyone can benefit from accurate, non-invasive blood glucose monitoring. Or perhaps we should ban everything that can enable "the stupid" to harm themselves.
- Retric 3y agoThere’s far more options than just those two. It may not be physically possible to have non invasive glucose monitoring of sufficient accuracy, until it’s actually demonstrated we just don’t know. The general point of the FDA is to prevent snake oil salesmen from conning people which makes this decision in line with their core mission.
- TeMPOraL 3y ago> It may not be physically possible to have non invasive glucose monitoring of sufficient accuracy. That's a pretty bold statement. Not economical with current technology? Sure. Not physically possible, at all? I strongly doubt it, and I would love to know the reason for thinking it.

- cosmin800 3y agoGoing to buy more Eli Lily stock, that thing will never go down this way. Keeping people from seeing their real-time blood glucose levels is just a move to keep them from becoming aware of how bad their sugary foods are and their pre-diabetic health. Fructose is way worse than glucose.
- faeriechangling 3y agoGlucose is still rather bad, but I'm on a fructose limiting diet anyways.
- gorb314 3y agoJust my two cents, but as a type 1 diabetic: I either want very accurate blood sugar readings, or none at all. And from what I know about people who don't suffer from diabetes: there is almost no reason to try and find out what your blood sugar is doing, because your body regulates it so well. So I just don't see the point of this. Non-invasive glucose monitoring just doesn't seem feasible, the accuracy doesn't help diabetics and it certainly doesn't help non-diabetics. I'm a naysayer on this, but I do hate having to continuously test my sugar and buy expensive CGM gear. Please prove me wrong?
- jwagenet 3y agoI’m not diabetic, but I can have intense energy/mood swings likely related to blood sugar. Non-invasive monitoring does sound nice to have a better understanding of what’s going on.
- gorb314 3y agoIf I were in your situation (which granted I am not) and mood swings related to blood sugar was a concern, I would pick up a simple finger-prick blood testing kit. It is fast, safe and most of all very accurate. That would then either put my mind at ease or convince me to see a doctor. Again, having what might be very inaccurate measurements of blood sugar won't help in this case either, I fear.
- omnicognate 3y agoI'd just go to the doctor.
- joshstrange 3y agoI don’t understand this view point at all. Widely deployed tech that is not as accurate has a chance to uncover trends no one was monitoring for and to improve over time as they have more data and iterate on the tech. If we took your approach with literally anything in the tech world we’d have nothing since the v1 wasn’t perfect. How does it hurt you at all if people have access to a rough estimate of their blood sugar levels?
- pedalpete 3y agoI believe the correct approach is to create a non-medical label for the test. Our watches have heart-rate monitors, not EKGs. An EKG is a medical device with highly accurate measurement of heart-rate for medical purposes. A heart-rate monitor, gives a decent approximation, not good enough for medical purposes. Nobody calls an EKG a heart-rate monitor. The correct term would let a consumer have some insight into their blood sugar levels, but a diabetic would clearly not be confused into thinking this was a replacement for the monitoring they require.
- kevingadd 3y agoMy fear is that "a diabetic would clearly not be confused into thinking this was a replacement for the monitoring they require" is an impossible bar to clear. We've seen how good ordinary people are at using technology even when it has clear documentation. Another post on this article also points out that traditional monitoring costs money on an ongoing basis, which would create a temptation to try and 'get by' with tech like this even if it's not adequate.
- pedalpete 3y agoThese are good points, but we can't ignore that this technology is valuable for non-diabetics. We also know that "preventing" technology from being used is a losing battle - though I'd be happy to hear of examples contrary to this. If a diabetic is going to attempt to use the device as a diagnostic, but they are aware that it is not fit for that purpose, that is their own choice. Like injecting insulin by "feel". Perhaps a better approach would be that insulin be delivered in collaboration with a certified device. That would close the loop on the amount of insulin being injected. I'm no expert on diabetes though, so i don't know the actual implications of that.
