Advice massively appreciated

Hi and welcome.

i would encourage you to get a doctor’s appointment as soon as you can.
Don’t delay while you do research and try to adjust your diet and make lifestyle choices (that could backfire on you and delay or dodge a diagnosis, which in turn could prevent you getting any treatment and monitoring that you need).

My personal experience is that there are some doctors who actively dislike patients who turn up with lots of evidence and a self diagnosis. Others are much more open minded and willing to listen. But none of them will take your home readings as proof of anything. Instead they will order their own set of tests, if they consider them necessary, using their own lab.

by all means continue reading and self educating, and posting here! But don’t do that instead of, or as a delaying tactic, to avoid a doc appt.

Hi and welcome to the forum, @LisaLeigh.

A reading of 12.3 is admittedly a bit high for a non-diabetic, but still possible. I guess it depends a bit of when you were tetsting your blood sugars (e.g. right after a meal).

To find out if you are truly diabetic, you would need to ask your GP for an HbA1c. If you are diagnosed, changing the way you eat works for a lot of us with T2 diabetes.

Stick with us. There are plenty of really knowledgeable members, who will be happy to help.

Again, welcome to the forum.
