So I'll assume that my pancreas is still functioning then. You are right because I have done 3 tests in a row with my metre and the difference can easily be half a mmol. So I guess that could be in either direction and it doesn't mean anything much if it's only 0.2 mmols.
So I've looked at this link and I see:
For the majority of healthy individuals, normal blood sugar levels are as follows:
- Between 4.0 to 5.4 mmol/L (72 to 99 mg/dL) when fasting
- Up to 7.8 mmol/L (140 mg/dL) 2 hours after eating
In Australia they won't even diagnose prediabetes until your fasting hits 6.0 mmol. I'm wondering how it is in Europe and the USA. Probably similar to the UK, isn't it?
I also wonder if I'm getting 8+mmol 2 hours after a meal with a small amount of carbs (I say small because I could have had a lot more of the sweet potato and rye pancakes that contributed to a one-hour spike of 11mmol that left me still in the 8s at 2 hours), even if I won't be diagnosed officially using a home metre, I should probably just assume I have a problem.
I would like a proper diagnosis but I'm probably not going to do another GTT anytime soon and if I stick with low carb eating, my HbA1c won't reflect how glucose intolerant I actually am.
I just imagine that before people develop insulin resistance, they can eat carbs, only spike to about 6 mmol, and probably return to base or fasting (in the 4s) within 2 hours. Is that how it works or does it take 3 or 4 hours for everyone to return to base?
Am I right to assume that if you sit 2 or 3 mmol above your starting point at 2 hours postprandial that you probably already have some level of insulin resistance?
