Do Proton Pump Inhibitors Increase Your Risk of Iron Deficiency?

Yes, proton pump inhibitor use significantly increases iron deficiency risk by approximately 2-fold according to this large population-based study. The increased risk results from PPI-induced reduction in stomach acid, which is essential for converting dietary iron into an absorbable form, particularly affecting non-heme iron from plant sources.

Dr. Kumar’s Take

This population study provides compelling real-world evidence for a clinically important PPI side effect. Doubling iron deficiency risk is significant, especially for populations already at risk like menstruating women, vegetarians, and the elderly. What’s concerning is that iron deficiency can develop gradually and cause fatigue, weakness, and cognitive issues that might be attributed to other causes. This reinforces the importance of using PPIs judiciously and monitoring nutritional status in long-term users.

Why Is Stomach Acid Essential for Iron Absorption?

Gastric acid plays a crucial role in iron absorption by converting dietary iron from the ferric (Fe3+) to the ferrous (Fe2+) form, which is the only form that can be absorbed by intestinal cells. This acid-dependent conversion is essential for absorbing iron from plant sources and iron-fortified foods, explaining why conditions that reduce gastric acid production can lead to iron deficiency despite adequate dietary intake.
