Celiac disease occurs when the body cannot digest or break down gluten-containing products that are found in wheat, barley and rye. For example, products like bread, crackers, and cookies contain significant amount of gluten. Eating gluten makes the body’s immune system go on the attack and create toxins. This abnormal, autoimmune response damages the finger-like villi in the small intestines that absorb nutrients from food. If left untreated, celiac disease can lead to malnutrition and other complications.
Celiac disease is more common than many people realize. In fact, it is one of the most common autoimmune conditions in children. It affects approximately 1 in 144 people in the western countries and the numbers are higher in certain geographic locations based on genetic and other environmental factors. Celiac disease is still largely underdiagnosed due to the varied presentation of clinical signs and symptoms.
