In the measurement here in the US (mg/dL), your 11.1 mmol/L is equal to 199. I don't know of any doctor that would think that's acceptable two hours after a meal. I'm also wondering about
the blood pressure. From what I know about
blood sugar and blood pressure, it seems to me those readings should be much lower no matter how old you are. If I were you, I'd see another doctor and have yourself checked out with new tests.
Neuropathy happens over a period of time because of high blood sugar.
