The Freestyle Libre does NOT use a tiny needle to measure your blood glucose. It uses a slender capillary action fiber that reads interstitial fluid beneath the skin and in the area of your fat cells. The only needle used is in the instantaneous application of the sensor. The measurement of blood glucose using the Freestyle Libre generally lags behind your actual blood glucose by about 15 minutes because interstitial fluid is not actually IN your bloodstream.
You can only view BG readings on a SmartWatch via Bluetooth and a 3rd party companion app which can display it on a watchface.. I have a Libre 2 CGM (btw @DalvinBrownWSJ you are slightly incorrect in your video about a CGM using a needle to measure blood glucose levels). A CGM uses a needle as a "delivery device" to place a synthetic filament in your arm, which in turn is attached to the sensor on your arm, It doesn't take the measurement of Blood Glucose using whole blood. It uses your body-fat's interstitial fluid in the back of the arm (the only recommended placement site) and through an algorithm determines an estimate on what your blood sugar will be (it has a window of about 10-15 mins on whole blood). You should also NEVER just rely on a CGM alone. The traditional Whole Blood finger-stick method should always be used if you CGM is alerting you to a Hypo- or Hyper- glycemic event. That is the most accurate measure,
I will summarize your video in 4 words: The technology isn't ready. This isn't to say that you didn't make an interesting & informative video. You did. But a more accurate title would have been "Research into Measuring Glucose on Smartwatches" or "Hurdles Facing Smart Technology in Measuring Blood Glucose".
Because 99% of people would literally cry if they felt that needle going through the top of their wrist from the watch plus that's not a good place for a blood test the back of your arm tricep area is the best place for a sensor. And it needs to be changes every 2 weeks or risk infection and pain. If you took the watch off that's it you gotta replace the sensor you can't just put it back in.
probably never, the big pharma companies would lose billions if Apple/Samsung put glucose monitoring in their watches. They will lobby and make sure the FDA doesn't approve it. Meaning even as a non-diabetic you are out of luck...unless...you won't believe this, they just got their continuous glucose monitoring devices approved for over the counter purchase for non-diabetics.
The used technology is like a sonar. An emitter send a beam through skin, and that is reflected back to a receiver. They’re saying that they changed light with another EMR, because of the receiver. For light, is used a receiver that converts light signals into electrical signals, using photoelectric principles. Another EMR (like microwaves or radio waves) are using different methods to be converted into electrical signals that can be interpreted as data. So for this reason, even if the emitter send same signals, the receiver use different technology. Hope that helps and you understand.
It’s obvious they are trying to develop a solution that doesn’t require a needle, as most people are terrified of them. Additionally, they could revolutionize smartwatches and make significant profits if they manage to measure glucose without needles-perhaps through a microchip inserted under the skin or even an earring. They must be on the right track.
And some of us diabetics are still sticking our fingers several times a day because Medicare won’t pay for a glucose monitor unless you’re on insulin. They don’t seem to understand that a glucose monitor would likely prevent us from needing insulin.
The continuous glucose monitors actually don't leave a needle in your skin. The needle places a monofilament the width of a hair and the needle retracts. They're painless.
@@MMathis Sorry to hear that they cause you difficulties. I'm finding mine very helpful in seeing how various things affect my glucose levels. It's been particularly interesting to see the large swings sometimes for no apparent reason throughout the day. I'd never have known that if I was using the finger stick method. The body is a mysterious thing.
There was a RUclips ad for a watch that claims blood sugar monitoring but I knew it had to be BS so I started researching and I was right especially for something that cost 47 dollars. Of course there are pages of positive reviews. Just like the drones that were made for the military or the flashlights that are strong enough to start a fire 😂😂
How can they not add an alarm to the freestyle monitor, why is the alarm only accessible through an App?? This makes no sense!!! Smaller watches can have an audible alarm set, WHT can freestyle lebra not have that easy function My shild has to be in Bluetooth range permanently to not lose signal, and here the alarm on my phone If the sensor has an audible alarm, he can call me when it goes off on low or high readings This makes no sense, and any company can grab the market by adding this to the sensor
I would be happy, if I could see the measures of the Abbot Libre3 Sensor on my Apple Watch. Don’t understand why that’s not possible. It works only with my Apple IPhone! Why? Is Apple blocking? It will take years to develop a bloodless system. Even big machine can’t do that! Perhaps this feature will never come!
It won't. You cannot measure Glucose levels unless it's performed via fluid delivery. Sweat, Other Medication & Lotions interfere with the skin;s natural barrier and oils. It is practically impossible - The only way is through either skin penetration or implantation of a sensor.
@@alandunbar4244 how do you think blood oxygen is measured in watches? The quest is to monitor subtle changes in body parameters that can be correlated to blood sugar
@@valqueenofValhalla Don't see how communism is related here. It's more to do with adversarial relations with China or Russia which I find sensible not to share data with them.

People if you’re still reading this thread, I have a watch it’s called Smart life, smart bracelet, ECG, blood glucose and blood pressure. It also tracks steps it tracks your sleep, but not very good not as good as the Applewatch
Please be aware that all the "smartwatches" available trough a google search just but out some random numbers loosly depending on blood pressure and steps/workout. They are fakes. There are a lot of reliable actual diabetic in youtube and online forums that review them. Crosscheck it with actual blood glucose readers. Or better ask an type 1D of your local community to test it for/with you. Imagine you have an actual high past 400mg/dl for several days because of an illness and think your bad feeling is just an cold. The brain works really slow and dump past some high level, duration and absolute insulin insufficient. Regards, Stay Healthy and away from online crooks.
Stronger light needed to go through the skin, heart beats are stronger, I’ve heard that 10 people right now are wearing test watches, they have been told to wear these watches all the time for a year, then all these data collected, from there software improvements maybe needed, that the last I heard and that was beginning of the summer so 2025 maybe the year, no doubt this will fly off those apple shelves and be a No1 market leader, I do prefer a giant company to throw millions into development and accuracy 👍🏻
Chances are... light won't help.... it's been tried to hell and back.... Currently the technology is using much lower/higher wavelengths than that of light.
You cannot measure Glucose through light and never will be able to. Glucose is a molecule that attaches to red blood cells and is too small to be measured via that medium. It needs either Fluid, Blood and/or laboratory microbiological analysis.. The skin is the main problem. Oils on your skin, lotions, other medications, heat, cold etc interfere with even with current body sensors on smartwatches. It would be great if they could, but at this technology stage, even CGM's have the limitations mentioned above,
Sure “level of accuracy” or couldn’t find a way to squeeze profit from something what would be a one time purchase. A subscription was such an obvious scam. Of course they had to stop from developing a revolutionary and helpful technology.
There’s tremendous opposition to the advancements in diabetes management from government and all healthcare sectors. If the disease ever get cured, there will be impacts to healthcare revenue, insurance industries, and jobs lost.
the point is... it is not wantet by food corp - and the owner of food corps and apple/google/facebook etc owner are 2-3 huge Investment managements corporations.... if the not healthy food udreveal itself (not a meat (fat) is a problem to healt but sugar) .. the corps will not be beneficial of it...
That's true, but life doesn't always have to be seen through a black and white lens. I prefer to know which carbs I can eat (my body tolerates and doesn't spike blood sugar, when and where). This is an experiential learning process... trial and error, and along the way you learn little hacks that HELP you eat carbs, like eating carbs after eating protein, fat and fibre, since they slow digestion and allow the carbs (read delicious chocolate cake or ice cream) to be eaten without spiking blood sugar. Sometimes I just prefer a little colour in my life 😊
If Apple brings the Watch plus Apple vending machine which communicate with the watch and churns a meal according to Vitamins deficiency issues,Vitamins boost.protein boost,Fibre boost, healthy wholesome carbs from AppleVendor machine everyday giving me a good meal for about $10 USd plus healthy Milo with soy protein in it Than I me and steve jobs are on the same page If not it just same stupid merry go around with Apple,Goggle and Samsung For info this vending my place in remote village in India with a supercharger with 240kwH supercharge Ten charge and ten minutes to eat plus couple songs in a remote village in India Charging my Apple Car Than Tim Cook and me are on the same page So what u reckon Tim Just by where bees die by river Radiation spike or Jeff Bezos 1 dollar to watch a movir😂❤🎉😂😢😅😅
The comment at the end about the donut was unnecessary. If your sugar is high, you shouldn’t have any carbs (or should take insulin to lower blood sugar and to cover the donut). Even healthy foods like fruit have carbs. Please stop associating diabetes with junk food. It’s very ignorant and just makes the diabetes community think you’re stupid.
The consumption of a small amount of carbs should only EVER be done if you are prone to and/or encountering a Hypoglycemic event or to maintain a steady BG level around the time of insulin delivery. Sugar won't cut it in the long term (only an immediate rescue from severe/dangerous BG lows). However, Type 2 diabetics should be avoiding carbs period... unless they take insulin or a Sulfonylurea medicine like Gliclazide. (Metformin, SGLT2's and/or diet only will not cause Hypos in Type 2s)
Anything Apple man I don't even want to hear about it, why can't people just make an Android video about Android phones that are the best glucose monitor phones, f*** Apple.

Are there any wrist wearables available. For blood glucose
Why not just take a smart watch and add the glucose testing patch to it. Ok a needle is still needed but that would actually make me buy a smart watch
You can already do this..... apply the patch to your arm.... get readings on your phone (and your watch)
Because 99% of people would literally cry if they felt that needle going through the top of their wrist from the watch plus that's not a good place for a blood test the back of your arm tricep area is the best place for a sensor.

yeah the needle in CGM does not stay in, it just cuts the skin/tissue and leaves a little wire that measures glucose lever once every 3 minutes or so
Thanks for the information. Very well done.
It will revolutionise the world of endurance sports!

Good report.
They end up abandoning it, because it would not generate them such high income as replacing cgm every 14 days...

Service dogs can smell big changes in blood sugar. That is crazy..
How can we not invent a simple device that can do it too?
There’s a big difference between detecting a glucose spike like a dog, and measuring glucose levels.
It's fake or true
