Interview with Terrance Gregg, President & CEO of DexCom

Thanks for posting this interview.

One minor correction. Gregg mentions that the sensor uses blood. It actually uses interstitial fluid. This means that the value from the Dexcom will typically lag the blood sugar value in the bloodstream. I've heard one doctor mention that the interstitial value more closely mirrors the BG value in the brain. So perhaps this is a more useful number to know.

It's a great system, despite some flaws. In the last year I've seen a big reduction in my blood glucose fluctuations and an improvement in my overall control.

Dexcom is now on the third version of their system. Each version has had minor improvements over the previous ones. I'm still waiting for their second generation device.

Their stock isn't do much at present. When widespread insurance coverage for CGM arrives, I'd expect to see the stock go up.
