In my understanding, a “normal person” refers to individuals who do not experience any stomach discomfort. In our country, the infection rate of Helicobacter pylori is extremely high, with reports indicating that over 50% of adults are infected, albeit asymptomatically. Thus, it is certain that many so-called "normal people" are infected with Helicobacter pylori, also known as asymptomatic Helicobacter pylori carriers. This condition also requires antibacterial treatment because there is a close relationship between Helicobacter pylori and gastritis, ulcers, and gastric cancer. Even for patients with chronic superficial gastritis, if Helicobacter pylori is present, eradication therapy is advocated. If not completely eradicated, it often leads to the development of chronic atrophic gastritis, which is a more serious condition.
