The only treatment for coeliac disease or gluten intolerance is a gluten-free diet. However, those with coeliac disease must strictly follow a gluten-free diet for life in order to reduce the risk of associated long-term health complications, such as anaemia and osteoporosis, which can develop if the condition is poorly managed.
For people with coeliac disease even the smallest amount of gluten may cause symptoms to return and in the longer-term will result in damage to the lining of your gut.
For those with gluten intolerance, reducing the amount of gluten in the diet to a level that can be tolerated and reduces symptoms is sufficient. This is because there are no known long-term health complications associated with gluten intolerance.
