Can someone tell me what these are and how they work. I do not fancy the idea of having a needle permanently inserted. It would however be nice to be able to monitor blood sugars all the time. Know when they go up and down straight away.Help from whoever. regards

I had a chat with a distributor and a doctor about these and learned some interesting things.

Firstly, they are very new and really shouldn't be used to measure blood sugar. It sounds weird but they really aren't all that accurate right now and you still need to use regular testing to calibrate them and check for critical numbers, eg low blood sugar. the other downside is they are not that cheap.

However, they come into their own by letting you chart patterns. Because they check so often you get a great idea of your overall blood sugar pattern. The numbers may not be 100% spot on but the peaks and troughs are useful, especially during the night. For example, if you're waking up every day with high blood sugar you can just check the CGM and hopefully find a cause. Maybe at some point during the night you dropped very low and then rebounded high. Maybe you can see your insulin is wearing off too soon. Maybe something else.

I have no doubt that as they get developed the price will come down and the accuracy will go up and they will turn into a very useful bit of kit. However, right now they can be useful for certain people but may not be worth it for everyone.
