I notice if I’m not moving – I’m in bed, or I’m sitting in my chair reading in the evening – as soon I get out of bed (regardless whether it’s as soon as I wake up or after I lie there for a while) or get out of my chair, my CGM blips down for the next one or two readings and then returns to where it was. With no 15-minute lag.
@Beacher I have a very similar problem. As soon as I wake up, my bG starts to go down. But it does not return to normal until I eat. The only time I get a 15 min or so change is when I take a shower, the dexcom blips up for about 15 min and returns to normal after I’ve gotten dressed.
I’ve wondered about that – that when I move significantly after being immobile for a while, the interstitial fluid sloshes around, and that briefly alters the reading. Can’t find any explanation of why, or why it goes down and not up.
This isn’t typically my experience, but I notice this sometimes if I am immobile, running high and correct. If I am on a long drive and have a high BG, corrections just seem to stabilize my BG but won’t bring it down as long as I’m driving. The minute I step out of my car my BG starts to plummet. Ive seen the same thing if I wake up early high, take a correction and go back to sleep. The Dexcom line will stop rising but just stay high until I get up, at which point I plummet.
