Today my sugar went up for no reason to 320, i checked the insulin, the insertion site and the pump it was all clear. I took correction for 1.5 units only. It droped after an hour to 140. its cool but then i checked my pump there was 1.4 active insulin. i was worried about having a hupo. Do i have to be worried in such a case or shall i leave it. Does anyone have a hint of how to deal in such a satuation.
