I started pumping with a MiniMed 507 in Dec 1996. While I have not had any consistently continuing infusion problems in past, recently my sites seem to no longer work. Specifically, my Blood Glucoses (BGs) no longer drop even after multiple correction boluses.
If instead of a pump bolus I correct via an injection, then my BGs do drop, so I don’t think my (Novolog) insulin is the problem. I have always rotated my sites and I am not aware of having scar tissue. Also, I am experiencing poor site absorption even when using my belly. I personally preferred to not use my abdomen so I would not expect problems there, but I do have problems there.
I am posting here because I’m at my wit’s end. I’m not sure what to do other than go back to using injections. I don’t really want to do that. (It’s been so long since I used MDI, that I’m not really sure I remember how to do that!)
Anyone have any ideas and/or suggestions?
Additional tedious details:
I’m currently using a Medtronic 630G pump. I have been using Medtronic’s 6mm Quick-Set infusion set until recently when I started having site absorption problems. I tried switching back to using 17mm Medtronic Silhouettes about two weeks ago, but the absorption problems are still with me.
