Does anyone else experience higher than normal BG levels prior to an insulin set change? I find the insulin seems a lot less effective after about day 3 of a vial in the pump but after changing the insulin vial and set BGs are back to normal. I would appreciate any comments whether pump users experience this or not. |

Andy, I sometimes get erratic readings after the set change. Endocrinologist says the new set is settling in. I have been a diabetic for 40 years and have had a lot of injections (predominantly into my abdomen)...theory is I have damaged the underlying layer so it takes a while to establish a pathway. I occasionally experience some irritation around the point of insertion if I let the set go for more than about 3.5 days and I think this impacts on BGs (i.e. raising them a little...not quite an infection but certainly slightly inflamed). |

The three day mark is when the body starts to heal up round the cannula, so you should be changing every 3 days at a minimum..... |

The issue, as I see it, is that if I get elevated levels post changing the set for the next 8+ hours then every third day I am getting elevated levels (which I currently reduce with injections...recorded on the pump). This means that I have about a 1.5 day window out of three days during which I can get reliable data to drive changes in basal rates. Thus by delaying the changing of the set I am postponing the period of elevated levels post set....and of course if I have had a period of elevated levels dealt with by injections ... I have more insulin in the reservoir and can postpone it longer...devil and the deep blue sea! Helen |
