What is Celiac Disease?

Celiac disease (aka coeliac disease) is a genetic autoimmune disorder where ingesting gluten (a protein in wheat, barley, and rye) triggers an immune response that damages the small intestine's lining. This damage leads to inflammation and atrophy of the villi, tiny finger-like projections in the intestine responsible for nutrient absorption. As a result, individuals with celiac disease may experience symptoms like diarrhea, bloating, fatigue, and malnutrition. Over time, untreated celiac disease can lead to more severe health problems, including anemia, osteoporosis, weight loss, and increased risk of certain cancers. A strict gluten-free diet is the only effective treatment. Celiac disease is an autoimmune disease, not a wheat allergy. It's also different from non-celiac gluten sensitivity, gluten intolerance, or sensitivity to gluten.
