The Potential Role of Hypochlorhydria in the Development of Duodenal Dysbiosis: A Preliminary Report.

Front Cell Infect Microbiol 2022 19;12:854904. Epub 2022 Apr 19.

Department of Translational and Precision Medicine, University of Rome "Sapienza", Rome, Italy.

In recent years, the role of gastric and duodenal microbiota has acquired increasing importance in the homeostasis of the host, although, to date, most evidence concern the faecal microbiota. Indeed, the gastric, and duodenal microbiota are challenging to study, due to gastric acid, bile, digestive enzymes, and rapid transit time. Specifically, the gastric acid environment may influence their bacterial composition since the acid barrier protects against orally ingested microorganisms and leads to their inactivation before reaching the intestine.
