I am new to this and just learning. My dad has been diagnosed w celiac disease at 76. He was completely healthy, on zero medications, eating healthy meals cooked by my mom, and taking vitamins for years! When he was first diagnosed (after weight loss and weakness completely disabled him), ever Dr he saw said No, you can’t have celiac. You’re too old. But slowly we have learned that celiac in older people is more and more common. This is an auto immune disorder, yes? Are there any studies regarding the fact that celiac in seniors may be caused by the flu or shingles vaccinations? My dad had both last year, and then Boom! Total sudden change in his health, and vaccinations are known to cause auto immune disorders. Am I out of line here??? Has anyone studied this or even felt that this could be a factor??
