It is difficult for normal human stomach acid to kill H. pylori.
H. pylori is a kind of bacteria that is more difficult to kill and not easy to be completely eliminated. The flagellum of H. pylori can be colonized on the surface of the epithelial cells of the gastric sinus mucosa, which avoids the bactericidal effect of gastric acid; the urease enzyme produced can decompose urea, forming a local microenvironment conducive to settlement and reproduction, and making the infection chronic, etc. All these factors make it difficult to kill H. pylori.
At present, the killing of H. pylori mostly adopts quadruple therapy, which mainly includes an acid suppressant (e.g., omeprazole, pantoprazole) + a bismuth agent (e.g., bismuth potassium citrate, colloidal bismuth pectin) + two antibiotics (e.g., amoxicillin, clarithromycin, metronidazole), and the course of the medication is 10~14 days.
If the patient is diagnosed with Helicobacter pylori infection, it is recommended to go to the hospital in time. The above medications must be taken under the guidance of a doctor, do not self-medicate.
