Gastric as well as Duodenal Biopsies May Be Useful in the Investigation of Iron Deficiency Anaemia

Abstract

As well as confirming the importance of seeking coeliac disease in patients with iron deficiency anaemia, our results suggest that achlorhydric gastric atrophy is also a common association. Gastric biopsies should be taken in patients with no other explanation for anaemia. The finding of Giardia organisms in two achlorhydric patients, with a possible contributory role, suggests that duodenal biopsies should be obtained even if serum coeliac-related antibodies are absent.
