Which adverse effects are associated with long-term proton pump inhibitor use?

• A. Hyperkalemia
• B. Renal calculi
• C. C diff infection, hypomagnesemia, hip fracture
• D. Anemia

Answer: (C)

Long-term proton pump inhibitor use lowers stomach acid, which can disrupt the gut environment and nutrient absorption. This combination increases the risk of Clostridioides difficile infection because less acidic gastric conditions allow more pathogenic organisms to survive and colonize. It also can lead to hypomagnesemia due to impaired intestinal magnesium absorption. Additionally, ongoing acid suppression can reduce calcium uptake and bone mineral density, raising fracture risk, including hip fractures. Hyperkalemia and renal calculi are not typical direct associations with prolonged PPI use, and while anemia can occur in some contexts, the most consistently linked adverse effects are the trio of C. difficile infection, hypomagnesemia, and fracture risk.
