The Claim

Disruption of neurocrine, paracrine, or endocrine pathways regulating gastric acid secretion—including vagal stimulation, histamine release, or gastrin signaling—transiently elevates gastric pH, enabling acid-sensitive pathogens to survive and reach the intestine.

How it works
1 study reviewed
In plain English

When nerve, hormone, or local chemical signals that control stomach acid production are interrupted, stomach pH rises temporarily, allowing bacteria that cannot survive in acid to pass through the stomach and reach the intestine.

See the scientific wording

Disruption of the neurocrine, paracrine, or endocrine pathways regulating gastric acid secretion—such as vagal stimulation, histamine release, or gastrin signaling—can transiently elevate gastric pH, enabling acid-sensitive pathogens to survive and reach the intestine.

Why this might work

When signals that tell the stomach to make acid are interrupted, the stomach becomes less acidic. This lets harmful bacteria that cannot survive in strong acid pass through the stomach alive and reach the intestine, where they can cause infection.

  1. Study: Gastric Acidity and Microbial Escape Routes: Mechanisms Used by the Intestinal Microbiota and Transient Pathogens

    When the body’s natural signals that make stomach acid get interrupted—like during stress or illness—the stomach becomes less acidic for a little while, letting harmful bacteria survive and travel to the intestines. This study shows that’s exactly what happens.
