Coeliac disease (also spelled "celiac" disease) is an autoimmune disorder that affects the small intestine. It is triggered by the consumption of gluten, which is a protein found in wheat, barley, and rye.
When someone with coeliac disease consumes gluten, their immune system attacks the lining of the small intestine, which can lead to inflammation and damage over time. This damage can cause a range of symptoms, including digestive issues (such as diarrhea, abdominal pain, and bloating), fatigue, weight loss, and nutritional deficiencies.
Celiac disease is a chronic condition that requires lifelong management. Treatment typically involves following a strict gluten-free diet, which means avoiding all foods and products that contain wheat, barley, and rye. With proper management, most people with celiac disease can lead healthy, symptom-free lives.
