I’m writing this with a lotttttttttttt of built up frustration and a blood sugar of 329. I currently have the Medtronic 670G (which I’ve hated since I got it) and for the past 2 years now I’ve experienced FREQUENT pump site occlusions. Lately, it seems every single time I rotate infusion sites, I get a “insulin flow blocked” message and I have to go through the painful process of inserting a new cannula again and again.
Mind you, I had a baby in 2018 and at first, I thought the occlusions were only happening when I inserted the site on my abdomen where there were stretch marks. They never happened on my back sides. Then I thought, maybe they’re happening because I gained weight and I need a new cannula size. But I didn’t need a new cannula size when I was pregnant? Anyway I’ve lost about 30 lbs in the last 6 months and now the occlusions are happening even more and everywhere, including my back. So it can’t be the weight either. Idk about the stretch marks but I avoid them.
Could the occlusions be due to overuse of the sites?
I’ve brought my A1C down by 0.6 points in the last 6 months and it’s soooo infuriating that the only times I have extreme episodes of hyperglycemia are when I’m having pump trouble! It is also now 1 am where I live and I can’t sleep because I’m monitoring my sugar. I’ve changed my cannula 3 TIMES, 3 DIFFERENT SITES, and given a correction ONE unit at a time to avoid getting that occlusion message. It lets some insulin through and then sometimes it says it’s blocked again! My sugar has been high for 4 hours now. This pump only tells me that insulin is not being delivered when I try to bolus or HOURS later if I rely on undelivered basals. I can’t keep giving myself boluses to ensure that the insulin is going in. This is ridiculous and dangerous.
Please excuse the angry tone. It’s not you lovely people I’m upset with (I love this community). But this pump… UGH it’s hell. I’m flustered and desperate and don’t know what to do anymore.
