Has anyone heard of these or even used them? I'm wondering if it would be worth it to do a little experimenting and thought it would be an interesting tool to experiment with.
I've been wearing a Dexcom CGM since March 2007, the product has evolved several times in those 5 years.
A CGM is very different to a standard blood glucose meter because you get the context of where your blood glucose has been and where it may be going. Wil Dubois has an excellent book that I've recommended called Beyond Fingersticks. The book helps explain the differences and is CGM agnostic.
Within 6 months of starting on the CGM my A1c test dropped by 1%. It hovers around 7.2-7.4% these days. I couldn't accomplish this without the Dexcom.
In the US, the Dexcom is generally covered by insurance for folks with Type 1 diabetes.
Hope this helps.
