Hi,

My husband had a blood test in March this year and was contacted last week (August 2025) by a pre diabetes advisor to explain his level was 42 over 5 months ago.

The chat with the advisor was helpful but we are concerned that the result is 5 months old.

Would the forum recommend a CGM, so that we understand his current level and then gain an understanding of how food, drink and a revised diet impact him over the next 3 months?

We would really appreciate hearing from the forum community.

It is something we are seriously committing to doing but thought it wise to ask for input here and also recommendations for CGMs.

Many thanks in advance for your feedback
 
Hi and welcome to the forum @Johnianna . A 5 month delay , that's not good. At least your husband has now been contacted. D2 members generally use a glucometer (finger prick device) to test their blood sugars. The best way yo get the most out of one is to test just before a meal and then two hours after. If the post mean result is less than 2 mmol/Ls than the first reading your body has coped well with the meal.
If not then one can make adjustments to your meal. Using glucometer s in a systematic way you do get the best out if them
As for a CGM I use both a finger prick device and a CGM. The CGM in my view gives you far more information. You can see what your blood sugars are doing at any given time. The negatives , you can become obsessive with the readings. I know I did, but now I just glance. They are expensive, but very useful, even if you only use them a couple of times. They can help you to figure out what foods raise blood sugars and what foods don't. They show you patterns and trends. They are definitely a nice to have device, but once you have figured out your foods , you don't need them or you can use one from time to time.

@Melgar -Thank you for the welcome and the information. really useful and very much appreciated.

Can I ask which CGM you use and if you have a view on its merits / limitations.
Thanks again @Johnianna

I use a Freestyle Libre 2 @Johnianna . I live in Canada so the Libre 2 is actually the Libra 2+ in the UK.
 
Testing has great benefits in fighting against pre diabetes.
A CGM is perhaps the most convenient method of testing .
But you should plan for using one. By this I mean formulate a list of foods you want to test and use this information to base your diet on.
I used a CGM in the summer of . I had two sensors that offered [emoji[emoji6]] days cover. This was enough to eliminate certain foods to my diet and also to include others .
I still use a CGM every few months just to see I’m on track and it feels like a treat
