Hi
Can a smart watch give you blood glucose readings?
I have seen them advertised but do they really work?
Thanks
Hi

I just want to ask you to be specific about what you want to know here.
There are many 'smartwatches' on the market which can communicate with your smartphone and a Constant Glucose Monitoring (CGM) sensor device (such as the Freestylye Libre) using Bluetooth technology. As long as the phone / watch has a suitable app installed then you can see your glucose levels on your watch.
I have seen some other devices starting to appear on the market. These watches have a sensor on the back and appear to be claiming that they can measure blood glucose directly. I am thinking of testing one myself as they ONLY cost about £20 to £30 at the bottom end, but I've seen no evidence that they are approved as "
Medical Devices" so their accuracy may be somewhat dubious. Look at Amazon and check the user reviews - it's a pretty mixed bag of responses. The devices could be good for trend analysis though.
Whilst not wishing to appear too disparaging about cheap Chinese goods, the low introductory price makes me wary. If you were to Google "non invasive blood glucose testing" (or similar) you will find many products which have been in the pipeline for a while but they are clearly going to cost ££££ when and if they are eventually released. Getting FDA and EU approvals for a medical device is probably the biggest obstacle here.
