I Tried a Non-Invasive Blood Sugar Watch. Miracle or Scam? 

I would like to know if there is a long delay I suspect the skin will not fluctuate quickly unless you have high glucose values for a long period.

I'm hoping there will someday be a watch that keeps good numbers. I'm sick of my glucometer! lol I can't afford, currently, the continuous meter. I'm keeping my eyes peeled for something that keeps up with sugar changes quickly and is reliable and reputable. Thanks for your video!!

We could not find any whatsoever on Amazon. I suspect Amazon may have started restricting the sale of these items. Family members suggested that big pharma bought them up to eliminate competition. Guess that perspective would depend on how well any work at all vs not at all.

It's not the skin. The skin has a very slow reaction time to the chemical composition of the blood, more than 24h. As I explained earlier, the electronics of this non-invasive meter camouflaged as a watch, is an low power high frequency alternating current measuring bridge. Stricto sensu, the application of the technique is not wrong, since the bathroom scales to measure body parameters (those nice ones of glass with two steel strips to be standing on), are working under the same principle and the same small battery. The detail is that the body portion used by the scale is very large: The lenght of two legs and the pelvic zone, giving more body volume to be evaluate, compared with barely 0,5 cm² under the wrist watch, touching a poor blood irrigated area. Although, different is the working principle of the fingertip oxygen meter, which sends an low power red or infrared beam to the skin and a light sensible diode (think on a light sensor) built in an circuit changes its parameter due to light interference with the light that bounces back from the tissue and under the blood irrigsted tissue of the fingertip, which varies with the oxygen concentration of the blood in an satisfactory accuracy of 1%. Perhaps the non-invasive wrist watch is not fast enough to catch spikes or hypoglucoses, due to its bad position over the body, but the principle is probably correct. An innovation could be that on the same wrist watch, the oxygen percentage and glucose content may be correlated by combining both techniques, or puting the HF circular electrodes on the bottom side of the wrist, where the veins are visible. I suggest our friend to repeat the same experiments with the three watches, butthis time turning them 180° around the wrist. Probably the readings will improve.

Please try placing these watches on a table surface, measure the GI and then tell me the result. Most watches will show a result, because they are simply programmed to show a certain GI at a certain time of the day, for example a low value in the early morning, or a high value around 9:30 to 10 am, after breakfast. Eat nothing for a day, and then measure around 2 pm. Eat 50 g of sugar at 6 am and then measure.

You are correct. These cheap watches just have a standard blood sugar profile. It's the same every day. I tested one myself, and I have the data to prove they are rubbish.

Why would you waste your money on Ali Express on something like this that is related to health?

​@@canuck21Because it's still better than Temu?

It’s a toy😢

@@MetalheadAndNerd Why not eat rotten egg? I mean it's better than eating poop right?

Could have been the Glucowatch. I'd imagine they were in development 30 years ago because they came to market in 2005 or so.

things arent changing. non-invasive measuring of whatever has been subject of research for several decades all over the world. but there are only very few applications for it, and invasive methods are often the only way and always more reliable.

What was interesting at that time was the piece of equipment they were using for the non invasive test. It was the size of a refrigerator lying on its side. I laughed and told the researcher that it was sure pretty large to be hauled around for use. She stated that they were then trying to verify the accuracy of the device and not worrying about the size. They would make it much smaller if the accuracy could be gotten.

You can bet your ass Apple is researching this topic heavily. It would be THE killer feature.

@@terriplays1726yeah, but I think it might be a long way before it’s accurate enough for t1d. However if u want an idea of how your body reacts to food or sport for healthy ppl, it does not have to be so reliable.

Yup, it’s nice to see tho, that they are not selling something that they know it doesn’t work.

NO the issue they have right now is there getting a copy right claim on the patient. Some company is saying they stole there invention. That's why it hasn't been out yet.

@@BewefauI cannot confirm your claim anywhere. The technology doesn’t even exist yet, how could there already be a copyright claim? Seems a lot like you just made it up.

⁠@@ZimZam131 It can happen. Even if there is no real product on sale, there can be tens of licensed technologies.

​@@jaerg91because Apple don't want to get Sued!

Won't even move me to slightest bit to purchase this. We still need our blood pricked for accurate result. Our life depends on that 😅

Samsung, and Apple watch will be the first 2 to the market with it Samsung has predicted it being on thier watch 7 pro when it comes out. and Apple says they are close and maybe 2 years out still on the Apple watch Ultra X

I bought a Samsung Watch for blood pressure measurement. Such non-sense tech. I mean, in my case, the upper arm blood pressure monitor barely gets consistent readings (my pulse can go down to 50ppm and upto 90ppm in seconds; that makes it tricky to measure anything), but at least that tech is at least "official" and with 2 or 3 measurements, you either get a valid average or need to retry a few minutes later. But the Samsung thing just takes one blood pressure value as its calibration point. What is the point, when my values are inconsistent? Does the thing at least warn about the issue? No, why would it admit defeat?

Were you able to return them for a refund? I once bought a smart watch off of amazon I wanted specifically to keep track of my heart rate...after fussing over it for 3 weeks, I finally gave up on it (very inaccurate) and even after all that time, Amazon let me return it for a full refund.

All those `smart` watches can read pulse even on bologna. No matter the price. Which is absolute baloney ;0) @@sarowie

It's quite possible that they are real. Knowing Apple though, they won't put something like this in their watch unless they're certain it can be useful, _dependable_ and decently accurate. My guess is that the technology just isn't quite there yet.

@@Dojan5they have been working on it. The fact that they haven’t incorporated it yet says they aren’t there yet.

Will they ever improve them?

@@Nasserist1969 All I can tell you is that Apple is exploring a noninvasive way to measure blood glucose levels. The noninvasive technique involves shooting a laser under the skin to determine the concentration of glucose. Apple has been working on needle-free blood glucose tracking technology for 12 years, but has not yet shown any meaningful clinical data.

Check out Dr. Ken Berry to permanently reverse T2 diabetes. It IS ABSOLUTELY POSSIBLE!!!

😅😹😂... 🙊

I think Samsung does the same for.blood pressures is it just random numbers?

Thanks. I don’t have to watch the whole god awful video now !!

Chinese scam as always.

I have one of these pice of sh*t and it seems to increase the glicemia on the moments they expect me to est, even if i’m fasting…

I wear my watch continually, the reading always, says 6.7. Or 6.5 my blood sugar is actually reading14 this is second watch. Usless

They can also not measure anything and just have a set number based on the time. Cheap heart rate watches do that too. At night they just show an average person's heart rate. In the morning it's higher, during the day low, till 12 when many people take a break and walk around. It's insane that this stuff is even allowed to be sold. It's clearly scamming

@@tharealmb thats my point exactly, it’s simply measuring the time in that case lol

Me thinking the same. Cgm has a known lag too and is different because what’s it’s measuring. If this is ever accurate it’s going to be more like cgm or a mix. Light works for oxygen to some degree (I’ve gotten random numbers from mine too). It could by detecting some trait in the reflectivity or conductivity. But as he said no manual says how to use or how it works so you could know oh it’s going to be x min off or I have to hold it tight to the skin. Or even expect y percent difference from serum levels. All of which will apply to the real technology when it’s live. I think wolf had one at nearly double the price and I can’t imagine a el cheapo one being anything. A no name brand is a hoax big a larger company has more skin in the game so there would be sure it’s measuring something and consistency to it not a random number generator as some pointed out

Yep i have one and noticed the same, basically always in the 6.1-6.9 area, even when i know i was high blood sugar (200-300 range - sorry dont know the conversion)

The readings are guessed based on formulas of data you input at setup. Age sex height. . A sensor can read a pulse(HR) But it can't "scan" through skin and blood vessel membrane and analyse the chemical composition of the blood to give you glucose levels. There so many other nutrients in the blood at the same time. Hard to believe the sensor can distinguish them😂

@@vladvld3433however we know Apple having been working on non invasive monitoring for some time, in theory you can measure BG based on how light is absorbed by blood, the trick is to make this accurate enough to be medically useful. Clearly no-name smartwatches aren’t doing the amount of verification required, but one day there’s a chance we’ll have something. As a T1 using Libre paid for by UK NHS it’s not going to be that big a deal, nice to reduce costs and waste, but for other diabetics who don’t get free Libre then this could be huge.

@@vladvld3433 Have to agree, it's probably just using some junk formula based off heart beat, i.e. function would define low heart rate over time to be lower blood sugar and the other way around. Explains how after his workout, where his heart rate would remain higher for a bit due to recovery of lactose flushing, the thing gave a high glucose reading instead of what it truly was.

OK. Read this after my own comment. Started on reading the comments. So with time, wear it right it does work. A good idea but watches like this, some at work have these cheap link to phone watches, Just to big for my thin wrists. A good idea though.

Would like to know which one you are using? If that is possible?

Which watch were you using? I would love to try it too as a t1d!

@@DanielGlover I have the KSO2 watch which I paid $70au for but I treat it as a guide and it’s great for that.

@@karenmcguire7292 Hi, I got the KSO2 for $70au , it is very thin and lightweight with a silicone strap and often forget it’s on my wrist it’s that light.

It appeared that Tom did the readings when is numbers were steady. Making a reasonable assumption that the watches, as well has the G7, are reading glucose in the tissues and not blood like a fingerstick.

I hadn't thought about the Type II benefit, but you are correct, if there is any level of accuracy, would be better to have some reference than the dreaded/avoid of the finger stick for type II; which I understand because I am Type I for 50 years, husband is now struggling with Type II - he is on medication, but has developed resistance over the past year and now on 4th Type II medication. Thank you for suggesting.

The processed food industry and sugar industry would pay a fortune every year to keep any non invasive technology from ever being accurate. It would destroy 100’s of billions in revenue for all colas, junk food and 1000’s of patisserie bakeries.

@@nonlinearthinkingBIG BLOOD SUGAR STRIKES AGAIN

@@nonlinearthinkingApple are a trillion dollar company and it’s in their history of not listening people telling them no. Just look at the iPhone. Telecoms wanted a lot more control of what the iPhone was allowed to do. But Steve jobs said not in this life time. Food companies trying to buy them out would just push them harder to release it.

what do you mean ? careful.....you use them in addition to your standard procedures, and make a table of your values, over a couple of days. of course you do NOT rely fully on those 'cheap' watches. Just be responsible.

I noticed Medicare doesn't cover Walgreens meters, even though they are cheaper overall. I guess they aren't very accurate.
