Celiac disease doesn't affect the immune system at all. If anything, those with celiac disease have a stronger immune system.

Also asked, how does celiac disease affect the immune system?

Celiac disease is associated with an inappropriate immune response to a segment of the gluten protein called gliadin . This inappropriate activation of the immune system causes inflammation that damages the body's organs and tissues and leads to the signs and symptoms of celiac disease.

Secondly, is Celiacs an autoimmune disease? Celiac disease is a digestive and autoimmune disorder that can damage your small intestine. People with celiac disease might experience symptoms like diarrhea, bloating, gas, anemia and growth issues. Celiac disease can be triggered by a protein called gluten.
