I had to replace my son's Medtronic Minimed Paradigm pump a few weeks ago (after about a year) due to it failing to administer the correct amounts of insulin. I've no doubt it was due to the reservoirs leaking. Quite frankly, I think all of the reservoirs leak (not just the ones they've recalled) and eventually, they destroy the pumps. At first, his numbers being all over the place with no patterns whatsoever just made me think I was crazy, but then I went back to needles for a day or two and realized it wasn't me...it was the pump. When we got the replacement pump, things were much better, but now his numbers are starting to be all over the place again. Is it normal to have to replace a pump pretty frequently? I'm starting to worry about this. I mean having blood sugars in the 220's in the middle of the night some nights and in the 60s and 70s other nights with no other factor changes seems pretty dramatic to me. Any wisdom to offer?
