### What is Celiac Disease? Celiac disease is an autoimmune disorder triggered by consuming gluten, a protein found in wheat, barley, and rye. When people with celiac disease eat gluten, their immune system overreacts, damaging the small intestine's lining and preventing nutrient absorption. ### Symptoms Symptoms vary widely and can affect different parts of the body. Common symptoms include digestive issues like diarrhea, bloating, and gas. Other symptoms may include fatigue, anemia, and skin rashes. ### Causes Celiac disease is caused by an abnormal immune response to gluten. It primarily affects people with certain genetic mutations. Factors like infections, surgery, or emotional stress can trigger the disease. ### Diagnosis Diagnosis involves blood tests to detect antibodies to gluten and a biopsy of the small intestine to check for damage. Genetic testing may also be done. ### Treatment The primary treatment is a lifelong gluten-free diet. Avoid all foods containing wheat, barley, and rye. A dietitian can help you plan a balanced gluten-free diet. ### Risk Factors Risk factors include having a close family member with celiac disease, being female, and having other autoimmune disorders. The disease is more common in white people. ### Prognosis With a strict gluten-free diet, most people with celiac disease can lead healthy lives. The damage to the intestine is usually reversible.
