Hismouse reported that her c-peptide levels are 1.5. By some measure standards I've seen she's in the normal range on 2 I've found, and definetely too high on one. I don't know if there are more methods but perhaps she could clarify by which standard she was measured.

0.78-1.89 ng/ml (normal high)
0.26-0.62 mg/L (Too high)
1 - 5 (normal low)

From a logical point of view, this doesn't make sense, if Hismouse is really a type Mody 2 or a type 1, then why is she having high BG levels if she has normal levels of insulin?

I think that Nancy's thoughts about the digestive system being the main culprit behind many autoinmune metabolic disorders, are on spot. Some sort of imbalance in the gut system

I could imagine that some bacteria/yeasts in the gut are overrepresented and that those make substances that alter the function of insulin, that would mean that they produce molecules that will attach to the insulin, making something else of it and unuseable by the cells to transport glucose into them. Since they measure the c-peptide levels and not insulin directly, we can never know how much "real" insulin would be in the blood stream. Perhaps there is really an altering of the insulin molecule after it is in the blood stream.

Since those duodenal bypass operations seem to cure diabetes almost instantly in most type II and reduce dramatically the insulin comsumption by types I, according to a doc of another poster, I guess that the chances of the gut being the main culprit on most autoinmune disorders are great.
