Celiac disease, or gluten intolerance, is an autoimmune disease whose only treatment - at present - is to follow a strict gluten-free diet for life.
When an intolerant ingests gluten, its body releases antibodies, which will want to destroy this protein, but will also destroy the intestinal walls. The anti-bodies act on the small intestine and the atrophient. From this atrophy arises a malabsorption of nutrients, and therefore many health problems.
Before going on a gluten-free diet, it is important to consult a gastroenterologist who will recommend or not the gluten-free diet. Today there are many non-celiac intolerant and several levels of sensitivity towards gluten.
