BACKGROUND & AIMS: Proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) suppress gastric acid production, which can inhibit iron absorption. However, few data exist regarding whether these medications increase the risk of clinical iron deficiency. METHODS: A community-based case-control study evaluated the association between acid-suppressing medication use and the subsequent risk of iron deficiency.… Read more »
