Possibly I need to rephrase that then. In someone with insulin resistance, large amounts of insulin are required to maintain normal blood glucose levels. This defines the Type 2 classification. In the absence of this attribute, someone really shouldn't be diagnosed as T2. Being sensitive to insulin and having Type 2 diabetes is a contradiction in terms.
Having said that, I agree that there is a lot of misdiagnosis going on. If it doesn't look like T1, it gets diagnosed as T2. The result is that there are a lot of anomalies in the so-called T2 basket. There needs to be a definitive test for insulin resistance, and maybe they need a third classification - "idiopathic diabetes"
