Iron absorption in patients with Zollinger–Ellison syndrome treated with long‐term gastric acid antisecretory therapy

Gastric acid secretion is important for absorption of dietary non‐haem iron, and iron deficiency is common in gastric hyposecretory states such as after gastric resection. It is not known if prolonged, continuous treatment with potent acid suppressants such as omeprazole will lead to iron deficiency or lower body iron stores.
