What’s the difference between celiac disease, gluten intolerance, non-celiac gluten sensitivity and wheat allergy?
We use “gluten intolerance” when referring to the entire category of gluten issues: celiac disease, non-celiac gluten sensitivity and wheat allergy.
Celiac disease is an inherited autoimmune disorder that affects the digestive process
of the small intestine.
“Non-celiac gluten sensitivity” (what many call “gluten intolerance”) causes the body to mount a stress response (often GI symptoms) different from the immunological response that occurs in those who have celiac disease (which most often causes intestinal tissue damage).
As with most allergies, a wheat allergy causes the immune system to respond to a food protein because it considers it dangerous to the body when it actually isn’t. This immune response is often time-limited and does not cause lasting harm to body tissues.
