“Continuous” glucose monitors (CGMs) aren’t actually continual. Most take a reading every 5 minutes. But it’s easy to forget that. In any moment we see a number on our CGM display, and it feels like that’s our current BG. But it was calculated by the CGM up to 5 minutes ago, and will usually be …
Most CGMs (Continuous Glucose Monitors) require calibration by comparing with BG fingerprick samples. These help ensure that the numbers the system reports are a good analog for your current blood glucose. If left uncalibrated for too long the values can drift from reality, but the speed of this drift varies across systems. I wrote earlier …

Well, for the last fortnight I’ve been wearing three CGMs. It’s been quite enlightening. The three systems I’ve been using have been: …
Over the years I’ve spent some time living with multiple CGM systems: Dexcom G4 and G5 Medtronic Guardian2/Enlite (640G pump) FreeStyle Libre FreeStyle Libre with Spike/xDrip+ Incidentally for the purposes of this technical discussion, the Libre is a Continuous Glucose Monitor. Any lack of alarms/etc does not change this, even if “Flash” monitoring doesn’t have …
I’ve written about technology such as insulin pumps for a while now, so I figured it was time for me to show you the pump I’m using in 2018.

I’m currently using Dexcom G5 CGM sensors, and like many people I’m self-funding it. In Australia there is rarely insurance cover for CGMs (and where there is, it’s only slight) or funding support for those of us over 20 years old. So we so what we can to cut the costs down. One of the most …
