A study reported in the World Journal of Gastroenterology in December looked at the prevalence of coeliac disease in over 4,000 patients with iron deficiency, 206 of whose deficiency was ‘of obscure origin’. Further investigation indicated that there is a high prevalence of coeliac disease in patients with iron deficiency ‘of obscure origin’ and that a gluten-free diet can improve anaemia in patients with relatively mild coeliac disease.
