In my ideal world, I would not be dependent on Dexcom for warning me about lows. I’m 13 years into my T1D journey. I’ve used Dexcom for probably the last six or seven years. Before Dexcom, I went off of fingersticks and how I “felt”. And a lot of times I could feel a drop, or feel a low, and then I would confirm it with a fingerstick before taking action (unless it seemed urgent enough for immediate action without testing).
I don’t know if I’m remembering it inaccurately, but I really think that I felt all of those things for most lows pre-CGM. However, I do remember being caught by surprise enough times when I was already down in the 50’s or 40’s or 30’s before I felt it. But my low symptoms were strong enough that they would wake me up from a deep sleep…which was necessary bc Lantus always dropped me in the middle of the night. It’s amazing I have any teeth left after juice boxes every night.
Adding Dexcom certainly gives me early warning of a troubling trend to correct…and it certainly caught lows for me before I did in the early days of using it. But now, I swear I don’t feel lows or drops. I might feel nauseous, or hungry, or mentally slow with lows or drops now, but it all seems so much more subtle. I don’t break out into sweats or shakes or anything textbook like I used to the early years. I got the glycemic index wrong on dinner last night and went low after finishing my extended bolus. I don’t know if the “oh shoot” feeling of seeing the CGM graph is just overriding what I would feel subtly without the Dexcom? But it’s a toss up as to whether I felt the “oh shoot I’m loaded up with insulin, finished eating a while ago, and am 57 right now trending down” jitters vs actual low jitters.
So…are my instincts just rusty? I’ve gotten so dependent on tech that I don’t know my own body anymore? Or is it a combination of tech early warning plus long duration of this disease that has changed my physiology? Do you think there is a way to redevelop my innate physical sense? [I don’t really remember feeling highs pre-CGM…or post-CGM, if that makes a difference.]
