Pre diabetes?

[Bubbles254]

I recently had an a1c test which came back at 36 which I thought was ok.

I have however been trialling a cgm and have been pretty shocked by my glucose spikes and dips.

I generally eat fairly low carb but I do tend to have a small slice of sourdough with peanut butter for breakfast. Yesterday I also had a small slice of quiche for lunch around 1cm of crust, rest of plate was salad.

The breakfast resulted in a spike to 8.9mmol/l followed by a dip to 3.4mmol/l. Lunch had a spike to 8.5mmol/l, I then had a low carb dinner and my line was flat.

Based on this does it suggest pre diabetes? The spikes are well above the guidelines of 7.8 post meal for non diabetics.

I don't see how the ac1 is at all reliable if it is an average and I am having dips too which reduce the average.

9 is not very high. HBa1C is the gold standard though--when it's high it's because of repeated high spikes. Your numbers are fine and show that you are not diabetic. Eat low carb if it suits you, it won't do any harm but stop worrying about diabetes.

I agree.

@Bubbles254 look up reactive hypoglycaemia. I have it, my CGM shows similar to yours. I’m not diabetic and have good HBa1C.
it is very hard to be diagnosed, I have been to the doctors over the years about low blood sugar, and they never picked it up, as it won’t show on standard blood tests. Only monitoring my glucose throughout the day showed it. I have too much insulin production which causes dips 3-4 hours after I eat.
CGM massively helped identify triggers and reduce carbs, increase protein.
you are not being anxious there are other metabolic conditions besides diabetes.
