Typing problems too?
First, welcome Kari! We're glad to have you join us.
Yes, speech issues are not uncommon when low, particularly severe lows. I've had that happen once or twice when I was down in the 40's.
If this is happening to you well above 80-90, that's something else, and you should see a neurologist about it. One thing I'd add before I get you all riled up though: Are you getting enough sleep?
I have slight slurring issues, and reduced ability to say things that require very rapid, precise mouth movements when I'm chronically under-rested. Like many days in a row with 5-6 hours a night or less.
I used to be able to handle this when I was a yute (cultural reference: My Cousin Vinny, perhaps one of the funniest movies ever made and a tribute to Fred Gwynne), but it's become more and more an issue as I've gotten older. I'm 52 now, and have had diabetes for 15 years.
I don't think it has anything to do with the D. I will say, though, that when I'm chronically short of sleep, I'm more susceptible to the problem when I'm low.
Definitely get this checked out with a physician!
