Coeliac disease is an autoimmune disease. It happens when the immune system reacts badly to gluten. Gluten is found in wheat, rye, 和 barley. People with coeliac disease cannot eat anything with gluten in it. Eating gluten can cause long term gut issues. Coeliac disease is not the same as a gluten sensitivity. People who have a sensitivity to gluten can still eat small amounts of gluten.
Coeliac disease can happen at any age. There is no cure, but not eating gluten helps. A person with coeliac disease can still have a nutritious, balanced and varied diet.
