Hello all! I’m dealing with a rather baffling problem the past few days, and wanted to see if anyone could shed some light on what could possibly be going on here.
So, I changed my pump site Thursday morning, took my breakfast insulin on it, ate, went on about my business, no problems. Ate lunch later, took insulin via pump, lived my life - again, no issues. Few hours later, I’ve just arrived at my parents’ place to spend 4th of July together, and my BG’s running a little low with IOB, so I’m like, “Oh well, it’s snack time anyway, I’ll just eat a few multigrain tortilla chips and not take anything for it.”
An hour or so later, all hell has broken loose. I’m going to bolus for dinner, and find that my CGM is showing that my BG has rapidly shot up from the low 70s to 180. Well, I’m annoyed, but that venison spaghetti sauce was calling my name, so I just bolused for dinner, expecting that I’d probably go a little higher, but then come back down later. Never happened.
Throughout the evening I watched as my BG climbed higher and higher - 250, 290, 336, 350 - I was growing increasingly alarmed because this was entirely unlike me. Against all common advice, I began taking additional boluses; I just was NOT slowing down. I considered the possibility of a bad site, but disregarded this possibility because I’d been doing perfectly fine on this site all day until near dinner.
Around 11PM as I was going to bed, I was at 376. In desperation, I took a correction bolus by syringe to my arm (which has always absorbed faster for me, as I have very thin arms). I set alarms on my pump to wake me a few times throughout the night so I could make sure I was coming back down. I did, finally, about 2 hours after the syringe bolus, start to trend back down, I dropped briefly (not severely) low around 4 AM and was finally stabilized at 96 with no IOB by breakfast. I ate breakfast, and the severe spike started all over again.
So I finally changed my site at that point, using a new vial of insulin. But I’ve been getting mixed results. Breakfast this morning was fine - I pre-bolused like I usually do, and had no meal spike. But lunch and dinner today both showed the same pattern of severe post meal spikes, despite the fact that I’m eating the same foods that I always eat. Worse yet, I’m forced into doing exactly what I know I’m NOT supposed to do, and have to stack additional boluses to force my runaway BG to stop rising. I couldn’t even exercise tonight because I couldn’t get my BG to rise to a safe range for me to run - I guess I was still eating all the extra insulin I had to take after lunch, even though it had been over 5 hours earlier.
If I didn’t know better, I’d say I’ve got a bad site, but I’ve already changed it out once and I’m still having these problems. Is it possible that I somehow managed to get a bad site twice in a row? Are there any other explanations for what could be happening here? Any suggestions are greatly appreciated! Sorry my story is so long!
