After 3 years of pump usage, I'm seriously at the point of jacking it in and going back to MDIs. Over the years I've just had too many random and unexplained high blood sugars, sometimes following cartridge/infusion set changes, sometimes following cannula changes and sometimes for no obvious or apparent reason at all. I've always been super conscientious about sticking to good pump protocol and avoiding issues like air bubbles but alas these problems continue.
Most times these spikes are just too high to attribute to stress, illness or a miscalculated bolus and just leave me concluding that for whatever reason, there are times when the insulin just isn't get through to my bloodstream. I can't carry on exposing myself to the risks posed by blood sugars often in excess of 15mmol, so I just think it's time to go back to a regime that leaves me in no doubt that I'm getting both the necessary basal rates and boluses, even if it involves more discomfort and less flexibility.
