Celiac disease (gluten-sensitive enteropathy) is an autoimmune disease that affects the small intestine and can lead to impaired absorption of nutrients and the development of dystrophic changes in the organs and systems of the body.
The disease is associated with intolerance to gluten contained in wheat, rye and barley. Gluten is a protein that has sticky properties and is used to make bread, pasta and other foods. If a person has gluten sensitivity, consuming these foods will cause a variety of gastrointestinal and immune system symptoms.
Symptoms of celiac disease vary depending on the severity of the disease, but the most common include malabsorption, increased weight loss, fatigue, anemia, poor skin and nails, diarrhea and constipation.
