I'm curious when people on here change infusion sets? Is it at the first unexpected high?
Yesterday afternoon I changed infusion sets around 4:30, was 15.8 (284) at about 5:30 before dinner which was a bit weird, and was 22.1 (398) after dinner. I did a shot but I am always reluctant to change newly-inserted infusion sets, so I left it. My correction with the shot was minus the IOB since I didn't know if that insulin would kick in. By 11:30 I had come down to 11.2 (202) and did a 1/2 correction with the pump (thinking the correction from the shot might still be working), and went to bed.
In the middle of the night I woke up feeling weird but I did not get up and test, just went back to sleep. It very likely could have been a low ... In the morning at 8:30 I was 5.2 (92) and ate my usual breakfast.
Three hours after breakfast I was 20.2 (364). So I did a correction with a shot (this time also bolused with the pump disconnected to capture the IOB). It's two hours later and I've come down to 10.5 (189), so I'm now thinking I'm going to give lunch a try as soon as I come down, and if I'm high after that I'll change my site.
So I don't know if this is due to a bad site (maybe working for basal but not boluses?) or a rebound from an overnight low or my I:C ratio changing drastically for some reason. I changed my last site after only a day due to itchiness/irritation, and this one is itchy, too, so I'm thinking my old infusion-set-irritation-issue might be playing a part. I hate "wasting" infusion sets, though! I might try just moving this one to a new location, but that means I have to stick it down with Band-Aids which get ridiculously itchy.
