PS
If you get a formal diagnosis of T1 diabetes, you will need insulin. In the meantime, cut out carbohydrates, which will bring those numbers down a bit.
Do you have the other usual symptoms?
Thirst and a constantly full bladder and weight loss.
Are you young?
Make sure you ask for a glucode tolerance test for diagnosis. They often miss that out nowadays, but it's the best. If they'll do a c-peptide test too, you'll get information on whether you're dealing with T1or T2
I never had either of those, but since the treatment is working 5 years later, I think they guessed right
diabetes T2
