Even if the gastric mucosa is damaged, it will not affect the further invasion of Helicobacter pylori. The damaged mucosa is not going to cause harm to Helicobacter pylori, and the damaged mucosa may become more and more serious. H. pylori is a microorganism that can survive for a long time in the stomach, the bacteria will produce a large number of toxins, which can damage the normal mucosal barrier, leading to the occurrence of chronic gastritis, and if not intervened in a timely manner may lead to the occurrence of peptic ulcers, and even develop into gastric cancer. If the diagnosis of H. pylori infection is confirmed after examination, it is recommended to choose the symptomatic drug eradication treatment, commonly used “quadruple therapy” (e.g., amoxicillin, clarithromycin, bismuth pectin, omeprazole), and should consult with a professional doctor before using the drug, and take it at regular intervals in accordance with the doctor’s instructions. Because H. pylori is contagious and can be cross-infected through sharing meals, it is recommended that communal chopsticks be used for daily meals. If gastric mucous membrane damage or H. pylori infection occurs, please consult a doctor in time to avoid delaying your condition.
