Thanks @ phonic2k , incidentally I wasn't diagnosed in hospital after an infection, that must have been someone else!
It was a routine blood test a month after a couple of asthma attacks in the summer. No fasting or anything just a general check blood test.
Then a month after the blood test I was called to the surgery and told I was diabetic.... 5 months later I asked for anther test, BG down to 6.3% . I asked about my cholesterol and only then did the nurse look at my results and see that it was "a bit high",
(total of 7) .... she wasn't happy about my lchf diet and gave me the standard NHS recommended diet for lowering cholesterol and a prescription for Atorvastain, even though it can cause a rise in bs.
I have decided to test and have ordered an accu-chek meter, so we shall see ... watch this space!
