My morning fasting numbers for the last 3 months are from 4.4-5.9. The highest after a meal was 7.3 but usually they are much lower. I do get spikes after a run up to 7-9 (cortisol?) but then they go right down after 30 minutes. I run 4 time a week. So none of these numbers explain my A1c being 46. I am due to see the diabetes nurse in a couple of weeks so maybe I'll get some answers then. I am worried that she will put me on Metformin and I'll get dangerous hypos or she won't and I'll develop poorly controlled type 2. Maybe I need a cgm?
That's weird. Though the spikes after running make sense, as it is strenuous. You could just try long walks instead, go for (seriously long) distance rather than speed. That shouldn't cause spikes in any case.
I can put your mind at ease about metformin though: it doesn't cause hypo's. It just tells your liver to dump less glucose, might suppress hunger some. If the height of the HbA1c is to blame on your liver dumps, then that would fix it. (Provided you don't get lasting side effects. If you do go that route, ask for slow release met from the get-go and always take it with food, never on an empty stomach.) It's medication like gliclazide that forces the pancreas to put out more insulin, and that can cause hypo's. Met won't.
