When I change infusion sites, I have trouble controlling my BG for several hours afterwards. My endo tells me that the trauma of the insertion causes the area around the site to be poor at absorbing insulin for a while.
I’ve tried a few strategies to deal with this.
For a while, I would give myself a big bolus into the new infusion site, but this didn’t help much. The insulin would kick in eventually, but there often seemed to be a long delay.
I’ve also tried making the change right before going to bed when my insulin needs are the lowest. This strategy is often but not always effective, but I don’t like going to bed with uncertainty about whether I have a well functioning infusion site or not, especially if I have to make a bedtime correction to my BG.
More recently, I’ve started giving myself an injection with a syringe at the same time I change sites and then increase my basal by 20% for the next six hours. This is a new strategy for me and it seems to work OK, but doesn’t quite eliminate the spikes I get on the first day of an infusion site.
The second day of my infusion sites is usually the best.
I’m curious if other people have similar issues and if anyone has a strategy to suggest. Does anyone use a totally different profile on the first day of an infusion site vs the second?
Thank you for your advice in advance!
