GERD: The Daily PANCE Blueprint
Prolonged use of a proton pump inhibitor (PPI) is most likely to lead to low levels of which of the following nutrients?
A. Calcium
B. Magnesium
C. Vitamin B12
D. Iron
E. All of the above
Answer and topic summary
The answer is E. All of the above
Prolonged use of proton pump inhibitors (PPIs) is associated with multiple nutrient deficiencies due to reduced gastric acid production, which interferes with nutrient absorption. PPIs are linked to the following deficiencies:
- Calcium: Chronic PPI use reduces calcium absorption by impairing solubility, increasing the risk of fractures.
- Magnesium: PPI-induced hypomagnesemia can occur even after short-term use, leading to muscle cramps, fatigue, and potentially life-threatening arrhythmias if severe.
- Vitamin B12: Gastric acid is necessary to release vitamin B12 from dietary proteins; long-term PPI use may result in B12 deficiency, manifesting as anemia or neurologic symptoms.
- Iron: Acidic gastric pH enhances iron absorption by converting ferric iron to the absorbable ferrous form. PPIs may contribute to iron deficiency anemia in predisposed individuals.
