Coeliac disease - Lab Tests Online AU

Coeliac disease is an autoimmune diseasecharacterised by an inappropriate immune response to gluten. Gluten is aprotein found in wheat, similar proteins are found in barley and rye and to a lesser extent in oats.This response leads to inflammation of the small intestine and to damage and destruction of the villi that line the intestinal wall. The villi are projections, small tissue folds that increase the surface area of the intestine and allow nutrients, vitamins, minerals, fluids, and electrolytes to be absorbed into the body. When a susceptible person is exposed to gluten, their body produces autoantibodies that act against constituents of the intestinal villi. As long as the person continues to be exposed to the proteins, they will continue to produce these autoantibodies. When villi are damaged or destroyed, the body is much less capable of absorbing food including iron and vitamins. They may begin to develop symptoms associated with malnutrition and malabsorption. Malnutrition causes weight loss in adults and growth delay and failure to gain weight in children. Malabsorption causes diarrhoea and foul smelling bowel motions that float and have a greasy appearance because of the unabsorbed fats and oils in them.
