Helicobacter pylori is the only bacteria found to survive in the stomach and is also one of the highest infection rates among people worldwide. May 15th every year is designated as the national "No Pyloric Day", and learn about Helicobacter pylori together. Helicobacter pylori is a kind of bacteria that parasitizes in the stomach, adheres to gastric mucosa and intercellular spaces, and can survive in a strong acidic environment. Data shows that more than half of the population in China is infected with Helicobacter pylori. At present, there are still several misconceptions about the understanding of Helicobacter pylori among many people: misconception 1. Asymptomatic infection without active treatment of Helicobacter pylori is one of the very clear carcinogenic factors. In real life, many people do not know when they have been infected with Helicobacter pylori, but this does not mean that we can ignore the risk of Helicobacter pylori. For some susceptible populations, the risk of cancer in patients after infection will significantly increase. Li Peng, Chief Physician of the Digestive Center of Beijing Friendship Hospital Affiliated to Capital Medical University: After infection, there may be several days of stomach discomfort, which can cause some symptoms of acute gastritis, but most of us are actually unaware. For some so-called high-risk groups, when undergoing gastroscopy, it is found that there are actually atrophic changes, such as widespread atrophy and intestinal metaplasia. For these people, we should pay special attention and regularly undergo gastroscopy to detect early gastric cancer. Myth 2: Infection with Helicobacter pylori means that about 1% of gastric cancer patients develop gastric cancer after being infected with Helicobacter pylori. Infection with Helicobacter pylori increases the risk of developing cancer, but it does not necessarily mean that after infection, one will inevitably develop gastric cancer. The doctor introduced that the proportion of gastric cancer after infection with Helicobacter pylori is approximately 1%. There is no need for excessive anxiety after infection, and treatment should be actively coordinated based on one's own symptoms. Li Peng, Chief Physician of the Digestive Center of Beijing Friendship Hospital Affiliated to Capital Medical University: Some people may experience ulcers such as gastric and duodenal ulcers, as well as problems such as lymphoma. Some may actually be chronic gastritis, without progression to atrophy or gastric cancer. Myth 3: After Helicobacter pylori infection, the probability of complete eradication of Helicobacter pylori reinfection is low. It is understood that the overall probability of reinfection of Helicobacter pylori is low. For cases that are difficult to cure and cannot be eliminated after repeated treatment, antibiotics can also be selected through the cultivation of Helicobacter pylori. Li Peng, Chief Physician of the Digestive Center of Beijing Friendship Hospital Affiliated to Capital Medical University: Actually, there are currently very good methods for eradication. Currently, with triple or quadruple treatment, the eradication rate can be above 80%. According to our research results, the chances of new infections every year after eradication are approximately 2% to 3%. Of course, some research results may show that this proportion may be high. The chances of re infection are actually not many. After understanding the relevant knowledge of Helicobacter pylori, can we prevent infection in advance in our daily life? Under what circumstances should we undergo relevant examinations? Developing good habits to reduce the spread of infection From the current incidence of Helicobacter pylori infection,
