Coeliac disease is a condition which affects the villi in the small intestine of the digestive system. One of the symptoms of coeliac disease is poor growth in children. Explain why this might be.

When someone with coeliac disease eats gluten this causes damage to the villi in the small intestine. This causes a reduced surface area for absorption of food. This means that fewer nutrients such as amino acids and glucose molecules can be absorbed.This means there is less glucose available for use in respiration to make new cells.If fewer amino acids are absorbed, there are less available to build new proteins.Without new proteins and cells, growth cannot happen.Therefore children with coeliac disease who eat gluten may be short.
