I’ve been fighting some really weird blood sugar highs recently – occurring at times when I normally see a level line on the CGM or am otherwise crashing (like 3am, all the freaking time) – and before my last pump site change, it was just getting ridiculous, so I took out the set early. And found this monstrous bubble (as seen above) in the reservoir.
Sitting here now with my new set for the past couple of days….the highs are still hanging around. (And that 1 bubble doesn’t explain the “bubble” I’ve seen in my blood sugar numbers being steadily higher for several months now.) The time I notice it most is the overnight sugars as seen on my Dexcom CGM. I’ll go to bed at a comfortable and steady 110 or so. Fall asleep. Rudely awakened by a blaring high in the 200s for several hours overnight. Wake up. Drink water. Take correction bolus. Sometimes eat a cheese stick if I think it’s dawn phenomenon-related. And most times, it goes down and I’m good by breakfast-time.
I keep wracking my brain….what am I doing differently from the past year+ that is making this happen?? It’s not *always* the last week of my cycle, I haven’t changed any medications or vitamins recently, I don’t think I’m sick (or getting sick), my exercise regimen is better than it’s been in years, I haven’t changed my basal rates (this will be the next thing I do to try to counteract it)….my checklist of “what it could be” goes on and on. MAYBE I’m not drinking enough water lately and I’m slightly dehydrated? I have been downing a lot of coffee over the past few weeks of cold-weather spells we’ve had. (But I’ve moved to half-caf and decaf, shouldn’t that be OK?) And sure, some nights the highs will happen after I’ve had a couple glasses of wine and some snacks with my girl friends, but even taking those out of the equation, it’s still a LOT of unexplained overnight highs for me. And it shows in my A1c – up 0.4 from my last A1c of 3 months ago (which was up 0.2 from the A1c before that.) It seems like a small enough gain, but feels really big. I’ve got to shut that sucker down, and stop the upwards “bubble” trend I keep seeing. Now, if I can just figure out how to do that…..
