Coeliac disease is a lifelong autoimmune disease which is associated with chronic inflammation of the small intestine. Dietary proteins known as gluten, which are present in wheat, barley and rye, activate an abnormal immune response in the intestinal mucosa, which can lead to malabsorption of nutrients.
It is estimated that one in a hundred people have the condition and symptoms include bloating, diarrhoea, nausea, wind, constipation, tiredness, sudden or unexpected weight loss, (not in all cases) hair loss and anaemia and even skin disorders.
