Can H. pylori infection be prevented? H. pylori infection can be effectively prevented, mainly in the following areas: 1, the prevention of dietary management: H. pylori infection has aggregated, should be used to share meals; H. pylori resistance to the external environment is not strong, sensitive to dryness and heat, a variety of commonly used disinfectants are easy to kill them, strengthen the disinfection of tableware, keep tableware dry; strengthen personal hygiene, wash hands before and after meals. Clean up excrement in a timely manner to avoid contaminating water sources. In addition, regular and quantitative meals, do not eat unclean food, avoid spicy and stimulating food, less pickled and smoked, barbecue food. 2, the prevention of task environment adaptation: research has shown that the risk of Hp infection increases under stressful conditions. Should have a good understanding of the task environment, adjust themselves to better adapt to the environment to reduce stress. 3, sleep quality adjustment prevention: On the one hand, sleep quality and gastrointestinal function are obviously related. Those who sleep poorly are more likely to have gastrointestinal tract dysfunction and gastrointestinal diseases. On the other hand, sleep quality and immune function are related. Those who have poor sleep for a long time may find a decrease in immune function. 4, prevention of mental and psychological adjustment: some studies show that long-term anxiety may easily lead to irritable bowel syndrome and depression may easily lead to functional dyspepsia. hp infection may increase the incidence of functional dyspepsia, irritable bowel syndrome and stress ulcers. 5, the prevention of drug application: if there is epigastric pain, fullness, poor nausea and other highly suspicious gastritis or peptic ulcer, dyspepsia, you can first take acid suppression, gastric mucosa protective agent. When available, improve gastroscopy and Hp-related testing. 6, standardized treatment, timely consultation and treatment according to treatment norms. What is H. pylori infection? Helicobacter pylori (Hp) is a Gram-negative microaerobic bacterium that generally colonizes the epithelial cell surface of the gastric mucosa and produces highly active urease. Urease directly damages the gastric mucosa on the one hand, and on the other hand decomposes urea to produce NH3 to protect Hp from gastric acid and pepsin, while using Hp for colonization and survival. In addition, Hp can produce a variety of pathogenic factors, such as vacuolar cytotoxins and bacterial toxin-associated proteins, which lead to inflammation and immune response in the gastric mucosa where it colonizes. H. pylori infection is the main cause of chronic gastritis and peptic ulcer, and is closely related to the development of gastric cancer and gastric mucosa-associated lymph-like tissue lymphoma. H. pylori infection refers to the colonization of the gastric mucosa by H. pylori, resulting in localized damage to the gastric mucosa. The global prevalence of Hp infection is more than 50%, and is generally higher in developing countries than in developed countries. Person-to-person transmission is the only route of transmission, and the main modes of transmission are oral-oral transmission, fecal-oral transmission, and gastric-oral transmission. What are the signs and symptoms of H. pylori infection or any discomfort? The most common comorbidities of H. pylori infection are chronic gastritis and peptic ulcer, which are characterized by epigastric pain, mostly pins and needles or distension, associated with eating, and pressure on the painful area, as well as fullness, belching, and acid reflux. It is also combined with some symptoms of indigestion, such as poor appetite, abdominal distension and nausea. Some patients also present with bad breath only. Why does H. pylori infection occur? H. pylori is a microaerobic bacterium that depends on a microenvironment containing 5-8% oxygen for stable growth and cannot grow in atmospheric or absolutely anaerobic environments. More than the average person in the world is infected with H. pylori, and the rate of infection is higher in developing countries. In the natural environment, humans are currently considered to be the only source of infection. The main modes of transmission are oral-oral transmission, fecal-oral transmission, gastric-oral transmission, etc. 1. Oral-oral transmission: the most important route. When people eat together, Hp can be transmitted through chopsticks. It can also be transmitted orally through close contact of family members. In addition, hands also play a role in this transmission process. 2.Fecal-oral transmission: Hp can be spread by fecal-oral transmission caused by contaminating water through feces. 3. Gastro-oral transmission: It mainly occurs in young children and endoscopists. Because vomiting and gastroesophageal reflux often occur in young children, and vomit or gastroesophageal reflux may cause gastro-oral transmission of Hp. Endoscopy operators, who come in contact with the mucus in the patient’s stomach, can cause gastro-oral transmission of Hp.
