What is celiac disease?

Celiac disease is an autoimmune disorder where the ingestion of gluten — a protein found in wheat, barley, and rye — leads to damage in the small intestine. When individuals with celiac disease consume gluten, their immune system reacts by attacking the lining of the small intestine, which can lead to various digestive issues and nutrient deficiencies. It is not simply a digestive disorder, nor is it a heart condition or a type of food allergy; rather, it is a specific immune response to gluten that requires strict adherence to a gluten-free diet to manage symptoms and promote healing of the intestinal lining. Understanding this condition is crucial for those diagnosed, as consuming even small amounts of gluten can result in adverse health effects.
