Abstract

This article reviews iron and vitamin B12 malabsorption due to the use of proton pump inhibitors (PPI) and infection with Helicobacter pylori. The bacterium is in some studies associated with low serum values of both ferritin and cobalamin and has in several cases been shown to cause reversible deficiency of these nutrients. PPI depresses absorption of vitamin B12, but only one case of deficiency has been reported in standard reflux therapy. Case reports exist of PPI-related iron deficiency, but studies have not confirmed these risks. General substitution with iron or B12 supplements in PPI therapy can't be advocated. The safety of long-term use of PPI is well documented, but it is still unclear whether PPI accelerates the development of atrophic corpus gastritis in the presence of H pylori.
