H. pylori infection is not self-curable in the majority of adults, while some children may recover from H. pylori infection. H. pylori is a very tenacious bacterium that is resistant to high acidity and will colonize the gastric mucosa. H. pylori is the main cause of chronic gastritis, peptic ulcer and gastric cancer, and it needs to be eradicated through active treatment, and the commonly used clinical treatments are quadruple therapy and triple therapy, including antibiotics. It is worth noting that not everyone has symptoms after H. pylori infection, and many patients do not have obvious symptoms. H. pylori spreads through fecal-oral and oral-oral transmission, so it is important to wash your hands frequently in your daily life, try not to use public tableware, disinfect tableware often, and use public chopsticks. If you are found to be positive for H. pylori, it is recommended that you go to a regular hospital to receive advice and treatment from a specialist.
