Abstract
- Proton pump inhibitors (PPIs) are commonly used for the treatment of gastric acid-related disorders, and are generally well tolerated. However, by reducing the secretion of gastric acid in the long term, PPI can increase the risk of inducing an imbalance in the gut microbiome composition. Moreover, gastric hypochlorhydria that is caused by PPIs favors the survival and migration of oral bacteria in the lower part of the gastrointestinal tract, with a possible induction of pro-inflammatory microenvironment. Therefore, gut dysbiosis that is associated with the use of PPI has been found to cause adverse infectious and inflammatory diseases. In this regard, adverse effects of the PPI-related gut dysbiosis have been reported in different observational studies, but their clinical relevance remains unclear. Therefore, the aim of this review was to explore the available data on the PPI-related gut dysbiosis in order to better understand its clinical significance.
