Abstract
In 54 children with coeliac disease, mild iron deficiency anaemia or evidence of iron deficiency without anaemia were common at the time of diagnosis. Treatment with gluten‐free diet without iron medication eliminated all evidence of iron deficiency and completely normalized laboratory values. Subsequent challenge with gluten resulted in the rapid reappearance of suboptimal iron balance as evidenced by decrease in serum ferritin concentration.
