Hi there everyone, I would really appreciate if you could help me a little bit please. I am not sure if there is anyone else who has ever had this problem in the past but I would really like to talk with someone if some of you ever had it or with people who has more experience and can help me out. so here’s the thing – a few days into the use of the cannula does seems to stop absorbing the insulin into me, or at least it is decreasing the absorption rate pretty significantly? The reason why I could notice this is because that I need 3* as much insulin, however then later when I take it out it all does seems fine and insulin is flowing normally, can this be real at all? I would appreciate any information in regards to this. and yeah, to make it all clear: I am using Medtronic 640g and also minimed mio cannulas. Anything in this matter is going to be really appreciated. Thanks a lot in advance.December 19, 2017 at 6:59 am #2600DieGoGoGoParticipant
Oh yeah, you’ve noticed it alright as it does it all the time. that’s for sure. It has drove us all mad. Will only use sure t right now. it just needs a change every 2 days, however I do know that it is going to work 100% of the time!December 27, 2017 at 9:29 am #2608AdmiandParticipant
Hey there OP, I have to ask you something in regards to this:
so here’s the thing – a few days into the use of the cannula does seems to stop absorbing the insulin into me, or at least it is decreasing the absorption rate pretty significantly?
How much it is a few days? you should be more specific here. Like for example Medtronic says that you should change sites anywhere between every 2 to 3 days. you can find that information on medtronicdiabetes site – customer support.December 28, 2017 at 7:22 am #2609PudsteckParticipant
Oh well… I did have gone as many as 6 days with a single cannula (but that was at the most), however I do usually change it after 4 days and I don’t change it sooner because I don’t actually have another need to change it anytime sooner unless it is to adhere to Medtronic guidance which, cynically, I can suspect that it is because of the companies that actually want to get people to regularly purchase rather than a genuine need (I suppose it is a little bit like lancets).December 28, 2017 at 7:43 am #2611HingerParticipant

Well, in regards to this part. It is perhaps for the reason that you are describing up there in your original post that the Medtronic is recommending to change it every 2 to 3 days. and according to everything that you said and what I could conclude then, to be honest, it really does sounds to me as if you do have a need to change them sometime sooner than only the 4 to 6 days period that you’re currently changing them. Maybe if you’re going to do it you’re going to find out that it has worked out better, who knows?December 29, 2017 at 6:02 am #2613LarryTomphParticipant
Oh well, I will just try helping with whatever I can. I just can say that when I have been getting set up with my pump, my DSN drove home that I had to change my canula every 3 days or more often if needed, but not rarer than that. as much as I have been explained, the main reason for that being the fact that your body is going to start to heal around the canula and so the insulin absorption is going to dramatically drop down, something that you surely do not want to happen, I guess. And yeah, that seemed to be true and for this reason I recommend you to do the same and make sure to change it at 3 days or even more often if needed but not rarer. The reason I recommend you is that I did have left my canula in for 4 days a couple of times back in the days when I have been camping around and due to some reasons I left it for 4 days or so (main one being that it has been a little bit awkward to try and change it there – big mistake) and back then I did have seen a big and stupidly for me – unexpected, increase in the levels of my blood glucose. Since then I am being very strict about it and guess what? Everything goes smoothly without any blood glucose levels increasing. No wonder that you noticed having some issues with it if you change it on a regular basis at 4 days and sometimes even up to 6 days. hopefully this is going to be helpful.December 29, 2017 at 7:54 am #2614DonCSungParticipant
I completely agree with the previous poster, the more often you change it the better your levels would be. of course it depends on your general conditions/ statistics, however the same rule applies for everyone – the more often you change it the better it is. I personally need to change my set as often as every 2 days! I personally did have waited a few times for 3 days and each time when I’ve done it my blood sugar is always getting high on the third day. but 4 to 6 days… that’s a wow. If I waited for 6 days I definitely would end up in hospital, or at least most likely. Anyway, if you can wait 4 days then you could try changing it every 3 days and see what results you would have.
