H. pylori is usually suited to acidic environments, and alkaline environments limit it to some extent. Helicobacter pylori is a relatively common gastric pathogenic bacteria, which can be well adapted to the environment of the stomach, and the stomach contains gastric acid, Helicobacter pylori is able to reproduce in large quantities under the conditions of the presence of gastric acid, so it is generally suitable for survival in an acidic environment. Clinically, drugs such as omeprazole enteric-coated capsules and lansoprazole enteric-coated tablets can generally be used to inhibit the production of gastric acid, which can play a role in killing H. pylori by changing the acidic environment of the stomach. Therefore, an alkaline environment may have a limiting effect on H. pylori. When you are tested for H. pylori in your body, you need to actively cooperate with your doctor for treatment. At the same time, you should use communal chopsticks and spoons to avoid spreading H. pylori to others.
