Why don't the components of gastric juice damage the wall of the stomach in the absence of a H. pylori infection?
The components of gastric juice, primarily hydrochloric acid and digestive enzymes, are highly corrosive, yet they do not damage the stomach wall due to the protective mechanisms in place. The stomach lining is coated with a thick layer of mucus that acts as a barrier, preventing direct contact between the gastric acid and the epithelial cells. Additionally, the stomach cells secrete bicarbonate, which helps neutralize acid at the surface, and the rapid turnover of epithelial cells helps repair any potential damage. In the absence of H. pylori infection, these protective factors are generally effective in maintaining the integrity of the stomach lining.
