I have concern i got gullen barry syndrome 5 years ago do i have more risk of getting another autoimmune disease like celiac, aih,etc because i have history of one?

Maybe you do or don't. I know of no preventive action/treatment. There are some with a genetically defined risk of one or more of these afflictions. Be aware and seek out your doc if you feel a problem is starting.

CIDP, a chronic form of Guillain-Barre, would have already developed. An acute autoimmune disorder does not predict a new chronic co-morbidity such as Celiac disease
