My husband and I have no autoimmune diseases or chronic health concerns. The endo has not dx him poly endocrine syndrome type 2. They thought the dual diagnosis was a mute point even though they had not seen both initially dx at the same time. Since diabetes and thyroid issues go hand in hand. My son had been checked for Addison's and so far so good. We have been told by the docs it is about managing the conditions. I am now going to just be more vigilant when he is "sick" that he is going to be more likely to have another autoimmune concern. I have not found much info on poly endocrine syndrome to learn more about what to expect.
