Whats the difference between having celiac disease and gluten sensitivity?

Effect on the body. You can be intolerant or react to gluten containing products with cramping, diarrhea, hives , etc. If this occurs and your blood test and or intestinal biopsy are positive for tissue damage markers, anti-intestinal antibodies you have celiac. A negative set of blood tests/biopsy suggest just intolerance. Both issues are complex and the rational approach to management is the same, avoid gluten.
7. Gluten sensitivity is from celiac disease most commonly which is a genetic disease. One can have allergies to individual foods otherwise like wheats etc but not have celiac disease.
