For me, my low sensitivity started to decrease after about 15 years. The reasons for the Hypo unawareness can vary from super tight control, to simply having the disease for many years. CGMs can help with this, and at least point out trends, or you may want to look into a service dog that can detect lows, if your unawareness is pretty serious.
YES ME TOO.HYPOGLYCEMIA UNAWARENESS.MY EYES GO BLANK
i think when you are consistenly low for a while you feel it less and less. Last night I was 64 before bed and only caught it because I was taking my routine bedtime reading. This morning, I felt a little low and was 49!
I heard recently that hypo unawareness was due to autonomic neuropathy, but I haven't been able to check that fact anywhere yet.
I know exactly. It was about 8 years in?? Can't remember if my second daughter was born. I was driving home from a Dr. appointment where I had to fast. I guess I didn't eat in time and before I could make it home,( feeling fine the entire trip home, I might add) I suddenly woke up with my car on its roof in the ditch and I'm sitting on the side of a hill with some stranger telling me it'll be OK. Ever since then I've had issues.
You can bring some awareness back by keeping bs levels even or on the higher over time. Or at least not having lows should help I think.
