Celiac disease is a genetic autoimmune disorder that affects the digestive system. It is triggered by the consumption of gluten, which is a protein found in wheat, barley, and rye. When a person with celiac disease consumes gluten, their immune system responds by attacking the lining of the small intestine, leading to damage and inflammation.
The symptoms of celiac disease can vary widely, and may include abdominal pain, bloating, diarrhea, constipation, weight loss, fatigue, and anemia. In some cases, people with celiac disease may have no symptoms at all.
Celiac disease is diagnosed through a combination of blood tests and a biopsy of the small intestine. There is no cure for celiac disease, but the symptoms can be managed through a strict gluten-free diet. This means avoiding all sources of gluten, including bread, pasta, cereal, and many processed foods. With a gluten-free diet, most people with celiac disease can lead normal, healthy lives.
