Dexcom is going to market a scaled down version of their G7 CGM in 2024 for diabetics not on insulin:

Many believe this is a reaction to Apple who are believed to be making a Smartwatch that can use infrared to check glucose.

I've been using a CGM for 5-6 years now. I started a long time before going on insulin. The Freestyle Libre without insurance runs around $120/month or so I think, but that data is several years old.

If you're not officially diagnosed as diabetic the insurance may not pay for a CGM but if you're got reason to suspect your susceptible I think your Doctor will write you a prescription.

There's a large Diabetic forum with a section for CGM's at this website:

As mentioned, the CGM is great for showing you what certain foods do to your glucose levels.

Insulin dependent pilots who want a Class 1 Medical have to wear a certain type of CGM that has low glucose alarms. And they have to submit 6 months of monitoring data along with explanations for high/low readings.
