DH was diagnosed a few days ago. He had had gradual weight loss for a few months and more recently increased thirst. The GP measured his blood sugar as 20 and sent him straight to A&E. Hba1c was >100. The doctor was non committal, understandably, about whether it is type 1 or 2. She said he is on the cusp of having increased risk of type 2 - age 39, was overweight (BMI 28) before the weight loss, and mixed ethnic background. He is now being treated as if he is type 1 while we wait for the test results which will take 4 weeks. He is now on insulin and his blood sugars have stabilised a lot over the weekend (fasting sugar in the 6 range typically).
What I'm struggling with is understanding the context. I get the impression his Hba1c was very high - is this correct and does it indicate that it is more likely to be type 1? If it is type 2, does the high Hba1c indicate that it is more likely to need insulin to control it?
