What is H. pylori and how does it relate to our health? Listen to my discussion with you. A, what is H. pylori? Helicobacter pylori, a spiral-shaped, microaerobic, very demanding conditions for the growth of bacteria. 1983, the first successful isolation from the gastric mucosa biopsy tissue of patients with chronic active gastritis, is currently known to survive in the human stomach is the only microbial species. Gastric and duodenal ulcers, gastritis, lymphoma, and gastric cancer are all associated with H. pylori, and the worst outcome is, of course, the development of gastric cancer. Second, the route of infection? H. pylori is mainly found in the stomach, mouth and stool of infected people, so it can be spread in the population through the following ways: oral-oral route: Chinese people are used to concentrated meals, then Hp from the mouth of infected people through the tableware → dishes or soup → the mouth of uninfected people. Some mothers are accustomed to chewing food before feeding it to their children, thus infecting them with Hp. In addition, there is kissing. Therefore, it is important to pay attention to oral hygiene and prevent the disease from entering through the mouth. Fecal-oral route: Hp in feces contaminates water or food and infects drinkers or eaters with Hp. Studies have shown that low temperature can prolong the survival period of Hp, so food preserved at low temperature and contaminated with Hp will increase the chance of Hp transmission. Gastro-oral route: Hp is transmitted to healthy people through the vomit of infected people. It occurs mainly in nurseries and kindergartens. Avoiding these routes of infection will prevent H. pylori cross-infection. Third, how to confirm the diagnosis of H. pylori infection? The first step is to go to the regular medical department for examination, there are various methods, mainly C-13 breath test, urease method, pathological diagnosis, serum antibody test, C-13 breath test is recommended, non-invasive, non-radiation and high accuracy. Fourth, how to eradicate H. pylori? Standardized treatment in regular hospitals. Triple therapy, quadruple therapy. V. Do I still need to review and follow up? Of course, H. pylori is more stubborn, standardized anti-H. pylori treatment after two weeks of discontinuation of the drug to the regular hospital to review, by professional doctors to decide the next treatment measures. Gastroscopy is required for combined ulcers or other lesions. H. pylori is all around us, it can enter your body and bring you harm if you are not careful, but it can be prevented and controlled, good habits and standardized treatment will keep you away from them.
