Dennis, I wouldn’t disagree with your 1st paragraph. It is in fact a minority of T1s that have comorbidity with other autoimmune disorders. There is replicated medical research that finds comorbidity between ai T1 with certain other ai diseases. These occurences are beyond coincidence.
My query was to reach a narrow audience. I was not trying to raise a false alarm for all others with T1 or others with another ai disease for that matter. It’s true that there are a multitude of ai disorders known to medical science & medicine. But I would be remiss & guilty of misleading others if I were to list all those which I might find. Most would be irrelevant to my query bc the research on the topic at hand looks at a more narrow list.
I have had both GP 's, endocrinologists & my Immunologist/Rheumatologist tell me that T1s often have comordity with other ai diseases.
For anyone interested in medical research on this topic I suggest beginning with a search of – the National Institutes of Health Website.
– One easy to read article comes from Stanford & can be found at “Beyond Type 1” at
https://beyondtype1.org/type-1-diabetes-with-other-autoimmune-diseases/ . The researcher specifically names Celiac Disease, Lupus, MS, Thyroid diseases, Vitiligo, Addison’s & Rheumatoid Arthritis.
A general web search on the topic would also give you results.
