Very well done for going to the doctors AND getting a blood test!I hope you feel as much a hero as you are for doing that
As for the hba1c, yes. it's over the threshold for diabetes, and you definitely need to change some things, but it's not like you're having dangerously high blood sugars all the time.
Are you planning to cut the carbs a bit? That might be enough, especially in combination with the metformin.
You're not supposed to increase it before you see the nurse. Don't worry about it. Metformin is usually increased over weeks or months, not days.
I don't know anything about the results for your liver, but as for the cholesterol, I'd ask for a breakdown of your numbers when you see the nurse, and not worry about too much it for the first six months if you plan to change your diet in any way. Why not concentrate on your blood sugars first?
Good luck, and again, you're a very brave man to go to the doctors despite your fears!
