I’ve been using a Dexcom for about 7 months now, a G5 as of September, and one thing I’ve noticed is that it tends to overreact to exercise. For instance I just got back from a 50 minute strenuous bike ride, and by the last ten minutes of the ride it started giving me <80 alerts with a vertical down arrow. When I got in the house it was showing me at 70, still vertical down, but my fingerstick showed a much more moderate 107. Seeing a significant drop during exercise is expected–and desired: I was at a post-prandial 180 at the start of the ride–but I wish there was a way to have the CGM stay more in line with fingersticks and not overreact or overstate the drop.
Does anyone else have this overreaction problem and know a way to ameliorate it? One thing I’m wondering is whether sensor location affects it. I’m wearing it on my lower abdomen and it may be getting jostled quite a bit by the movement of my legs while I’m riding.
