Which CGM is actually worth buying?

I'm thinking of trying a CGM for the first time but I'm getting confused looking at all the options and prices.

I have Type 2 and I'm not on insulin. My main reason for wanting one is to understand what different foods are doing to my sugar and whether things like walking after meals actually make a difference.

Libre seems to be the one I hear about most, but I've also seen people mention Dexcom and a few cheaper options online. I'm trying to figure out the actual monthly cost too, because even if a sensor looks affordable, replacing it every couple of weeks adds up pretty quickly.

For those of you using a CGM, which one are you using and roughly how much are you spending each month? Is it worth using continuously if you're not on insulin, or would using one occasionally for a couple of weeks be enough to learn your patterns?

I'm Type 2 and not on insulin either. I used Libre for a few weeks mainly as an experiment. The biggest thing I learned was which breakfasts were messing me up. Some foods I thought were completely fine gave me a much bigger rise than I expected.

That's exactly why I want one. I don't necessarily want another device forever, I just want to see what my normal meals are actually doing.

Don't compare only the price of one sensor. Work out how many days each sensor lasts and then calculate what a full month actually costs. That's where the difference becomes much more obvious.

Yeah this is what confused me. I kept seeing individual sensor prices and then realised that's not really the number I should be comparing.

I use Libre and the convenience is what keeps me on it. I care more about whether I can reliably get replacement sensors every month than having the fanciest CGM.

Availability is underrated. A cheaper sensor isn't much use if you have to hunt around for it every time you need another one.

If you're choosing between Libre and Dexcom, first make sure the exact model you're looking at is officially available and supported where you live. A lot of comparisons online are written for the US and the products, apps and pricing aren't necessarily the same here.

Good point. I think that's part of why my searches have been confusing. Half the results I'm reading aren't even talking about the same market.

I don't use mine continuously. I'll wear one for a couple of weeks when I'm trying to understand something specific, like a new breakfast routine or what happens when I start exercising regularly. Then I go back to my meter.

This might actually make the most sense for me if the monthly cost is high. Use it with a purpose instead of feeling like I need to wear one forever.

Exactly. I make a little list before I start one so I don't waste the sensor. Different breakfasts, rice portions, walking after dinner, sleep, that kind of thing.

One warning from personal experience: don't let the CGM turn every meal into an exam. I became obsessed with keeping the graph flat for the first week and it made eating stressful. The useful part is seeing patterns over time.

Same 😂 First three days I was checking the app like it was the stock market.

I'm on insulin, so for me alarms and getting readings without having to remember to scan are much more important than they might be for someone who's mainly using a CGM to learn how food affects them. I wouldn't assume the CGM that's best for me is automatically best for you.

Also check phone compatibility before buying anything. It sounds boring until you discover after paying for the sensor that your phone or app setup isn't what you expected.

For me the most useful thing wasn't seeing that a certain meal raised my glucose. It was seeing what happened afterward. A short walk after dinner made a visible difference often enough that it finally motivated me to make it a habit.

That's the kind of feedback I'm hoping for. Seeing the effect in real time would probably motivate me more than just being told to walk after meals.
