Not really.. a T2 with insulin resistance would be overproducing insulin... if you were underproducing then you should get it checked regularly? Has it been checked since then?
Well, no I don't think that you are correct.
The test analysis from their tame doctor said I had insulin resistance and I was producing insulin in the lower part of the normal range. So - insulin production and IR but not over production of insulin.
I think that you are conflating the effects of IR on a fully functioning pancreas (which may well be the majority case) with the stage when the pancreas starts to be unable to over produce insulin.
To modify your statement "A T2 with IR would usually be
initially over producing insulin. After some time of over producing insulin, the pancreas can start to lose the ability to produce insulin. This is one aspect of progressive T2 Diabetes.".
I could well have had IR for decades but have been producing enough insulin to keep my BG under control.
The symptoms may well have only shown up when my pancreas began to fail.
This is probably one reason that some overweight and obese people can achieve a quick reversal by dramatic weight loss if they reduce the IR before the pancreas claps out.
However
one size does not fit all and I have test results to show that I am (or have been) someone with Insulin Resistance who is
not over producing insulin.
So your generalised assertion contradicts my test results.
I'm going with my test results.
