Coeliac disease is an autoimmune digestive disorder, in which the body has an allergy to foods containing gluten. Gluten is a kind of protein found in grains. People with coeliac disease react only to the gluten present in wheat, barley and rye. Coeliac disease is a condition where the villous lining of the small intestine distorts and disappears. Normally the intestinal lining is velvety. The villus increase the surface area of ​​the intestine, and this helps with absorption of nutrients. When people with coeliac disease eat food or use products containing gluten, their immune system reacts towards the intake of gluten, which leads to damage of the villus. Absence of villus leads to the lack of nutrition, because the body is unable to absorb the nutrients from food. In Ayurveda, coeliac disease is known as “Grahani”. Coeliac disease refers to imbalance in certain body energies resulting in severe impairment of the immune and digestive systems. This disease is the result of Agni (digestive fire) imbalance. Ayurveda describes coeliac disease as the result of an abnormal reaction of immune cells towards gluten.
