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

I tested 3 non-invasive blood glucose monitoring watches. I compared the blood sugar readings from the watch to the readings from my blood sugar meter and my Dexcom CGM. Do these non-invasive CGM watches really work?

IMPORTANT ANNOUNCEMENT:
Please be careful whenever you see commercials for non-invasive blood glucose monitoring watches. Not all these are sold only on Amazon.
After filming this video, I discovered several more models advertised heavily on Facebook. These commercials are often using video footage stolen from diabetes influencers with AI generated voiceover. I'm 99% sure these are all trash!
Please share this video with your diabetic friends, especially with those who are more vulnerable and more likely to fall for these. Thank you for your help!

I’ve been trying a similar smartwatch I bought from Ali express. I used continuously for about two weeks. My conclusions are: 1) it doesn’t measure my glucose level at all. 2) It’s just displays aproximate normal glucose level at given time, and algorithmically goes up or down according to popular eating habit (not even MY eating habit!). For exampe, at 8 am it gave 100 mg/l reading, and then at 9 am it gave around 120-140, with or without me actually eating. The pattern goes the same even in my fasting days.

After watching thus video a couple months ago, my LADA husband got really excited about an ad about the watch. So thank you for having done this video. You saved us from wasting money!

About 30 years ago I volunteered as a test subject of a "future" noninvasive blood sugar device. I was connected to an IV drip of insulin that had been highly diluted and this was used to vary the blood sugar down. Then glucose was used to bring the level up. The device they used was using infrared sensors aimed at the skin. They took blood from another IV about every 15 minutes and were comparing readings. It was quite an ordeal taking a full day. I was thanked and given a check and dismissed. I could not even find out who was considering making such a device then. It depended on the test results. So here 30+ years later things may be changing.

Thank you so much for doing a video on this! I’m a retired urologist/gynecologist in the USA. I’ve seen these advertised and knew it could mean danger for a Type 1 or Type 2 diabetic utilizing it to dose themselves with insulin. Hugs 🇺🇸

[MrRooney]

Was really wondering about these devices as their ads are everywhere, thank you for taking the time to test them

[shaman.alsharou]

Thank you for testing those watches on behalf of all of us!

[crystalstewart]

I am so glad you took one for thr team and tried these things. I have been seeing them pop up for over a year, but could not imagine, if they were real, why hasn't Apple or Android put the technology into their watches. I have been so tempted to buy one anyway. THANK YOU❤❤❤

I tried a $40 watch I got from Amazon. I kept getting good results on pulse, on Glucose. On blood pressure. I got the same great results for over 2 weeks. I then put my watch on a water bottle and again got the same great results in the same ranges as when the watch was on my wrist! What?!😮

My wife and I tried two different watches from Amazon, both were sub-$100 pricing. Let's just say the most accurate thing about either was that they keep a good track of time, and that's about it. Otherwise, they were also both just random number generators when it came to blood glucose levels. One of them also supposedly measured blood pressure, but I think it was just recording game scores from some on-line games.

My first clue that there are serious issues is that Apple has been working on this for a long time and they still haven't introduced it. It was rumored they were going to introduce it a couple years ago.

This is one of the most objective tests I've seen of so-called non-invasive glucose monitoring devices. I've been actively following the half dozen legitimate companies that are seriously working on non-invasive devices and none of them have technology whose price will come anywhere near $100. Instead they all appear to be targeting a delivery price of a wearable device that will be approximately the same cost as 1-2 years of CGM sensors.

Thanks for taking the time to put this comparison together. Excellently presented and vital information.

[thegooddoctor]

Yeah, I worked on this technology in the mid 90's - chemometrics - using spectrum light on the skin to create an evolutionary cross correlation algorithm to determine glucose values. It was rather difficult back then to get any real reliable reading. It was interesting Good content - thanks....

[terencehawkes]

Thank you for doing this Tom. I was hoping someone would do this and was glad it was you.

[wyosundancer]

Really refreshing to see an actual test/comparison

[trishmiscavage]

Thank you for doing this video. I just saw ads for these watches and was so excited, but decided to check reviews and see was actual people have experienced. Was disappointed, but kinda felt it was too good to be true. This is the kind of lie in the advertising that is very dangerous for people who simply want to do better for their health.

Thank you again. So much

[alphadog]

Thanks for your comparison video, we all will be "better consumers" (buyers) because of your service.😊

[bigdogmack]

You help me more than my doctor. Thank you for this information. I am type 2 Diabetic and I am 63 years of age. It is amazing how I have survived this long with reading above 250. I need to get this under control however i don't trust doctors anymore. I trust you more thank you.

[kyjennifer]

I hope they come up with a genuinely good non-invasive device for monitoring glucose during my lifetime. I'm so excited about the prospects.
