Confused With How To Diagnose T2

gav_red said:

Either I am missing something, which is probably the case, or the way t2 is diagnosed doesn't make sense!?

If for example I control my blood glucose through making good choices and get a good hba1c then my doctor would say I'm not diabetic anymore. Surely this is incorrect? My logic says the way to diagnose someone, regardless of their current hba1c, is to test insulin sensitivity. Perhaps give them a high carb meal and test 2 hours later. Otherwise you are just measuring someones ability to control their blood glucose.

My apologies if that makes zero sense, still in the early stages of learning about this condition.

What you describe here is a glucose tolerance test which some surgeries still use. My surgery only appears to use HbA1c which in my case has remained in the mid 30s since last September, so if a Dr saw my latest HbA1c result would assume I was non diabetic if he didn’t look at my history, present medication or diet.

I was diagnosed with a OGTT. I thought that was definitive.

Oh indeed, I think HbA1c (so long as your red blood cell count is normal) and the GTT are equally valid tests to diagnose.

The problem is, no-one knows how long our red blood cells live, so even on diagnosis the HbA1c can be skewed, and we see many people on here with anaemia and thyroid issues who still have the HbA1c rather than the alternatives.
