Proton pump inhibitors (PPIs) can significantly reduce stomach acid production by inhibiting the enzyme responsible for acid secretion. However, in most cases, this effect is reversible once the medication is discontinued. That said, long-term or chronic use of PPIs can potentially lead to persistent low stomach acid (hypochlorhydria) or, in rare cases, difficulty in restoring normal acid levels.
