Hi, thank you everyone for your replies, they are incredibly helpful. I finally got to see my GP who had to confer with her colleagues about the glucose result. I am definitely diabetic; the feeling is the impaired glucose result is due to my recent weight loss. I have lost nearly 2 stone since June.
I saw my diabetes nurse this morning for the first time. Feet OK, cholesterol level below 5, eye sight to be checked plus a referral to an educational group.
It's now diet controlled diabetes and lots of check ups.
