Type 2 diabetes is not an autoimmune disorder, but the systemic inflammation caused by RA has been linked to insulin resistence and to Type 2 diabetes. I am insulin resistent myself.  My doctor calls it "prediabetic", but I have been able to keep it at the "prediabetic" stage for seven years now through diet. My father is a Type 2 diabetic.  Early signs of this condition include an elevated CRP and raised white cell count indicating inflammation.  My doctor told me that I would be diabetic within seven years.  That was seven years ago.  So far, so good. Changes in diet such as eating a lot of raw vegetables and fruit, avoiding white bread and white potatoes, eating lean meat, and moderate exercise seem to be helping me avoid Type 2 diabetes so far.  Hope this helps!

Peace,
