I believe everyone has heard of the name Helicobacter pylori (Hp), which is currently the only bacterium found to survive in a special acidic environment in the stomach. Not only that, it is also related to the gastrointestinal tract and certain diseases outside the gastrointestinal tract such as gastric ulcers and gastric cancer. Helicobacter pylori has the characteristics of high infection rate, difficult to cure, and easy to relapse, so in daily life, attention should be paid to preventing Helicobacter pylori infection. The epidemiological status of Helicobacter pylori: about half of the people in the country are infected! Since its discovery in 1983, Helicobacter pylori has gradually become the most important pathogenic bacteria in digestive system diseases. According to epidemiological survey data, the infection rate of Helicobacter pylori in adults in developed countries is about 50%, and the infection rate in developing countries is as high as 60% -90%. In recent years, the infection rate of Helicobacter pylori in China has also increased year by year, which is one of the reasons for the increasing incidence of stomach-related diseases in China in recent years. According to statistics, about half of Chinese people are infected with Helicobacter pylori. The detection rate of adults in China is 30% -80%, and it has the characteristics of early infection rate, that is, the infection of adults often starts in childhood. Helicobacter pylori infection has differences in regions, races, economic and cultural backgrounds, living habits, occupations, etc. The infection rate of children also has different ages. The high infection rate in China is also related to the failure to implement a meal-sharing system. The dangers of Helicobacter pylori infection: from mouth to stomach, and other organ systems! As early as 1994, the WHO designated Helicobacter pylori as a class I carcinogen. According to statistics from the International Agency for Research on Cancer, gastric cancer ranks third in the cause of death from malignant tumors. Not only that, some studies have found that Helicobacter pylori infection is also associated with esophageal cancer, pancreatic cancer, colon cancer, and primary liver cancer. In addition to the digestive system, Helicobacter pylori can also be colonized in dental plaque. Many studies have also found that it has a certain relationship with chronic periodontitis and can also cause intractable bad breath. In China, Helicobacter pylori also has the characteristics of family aggregation infection, so infection in children is not uncommon. Although peptic ulcers caused by Helicobacter pylori infection are not common in children, it is currently found to be associated with chronic gastritis, indigestion, Chronic diarrhea and recurrent abdominal pain are closely related, and may be involved in the occurrence and development of children such as nutritional iron deficiency anemia, growth retardation, malnutrition, idiopathic immune thrombocytopenic purpura, and chronic urticaria. Therefore, Helicobacter pylori infection has brought great harm to the health of adults and children. The advantages and disadvantages of Western medicine treatment of Helicobacter pylori are currently the most ideal treatment plan for the radical cure of Helicobacter pylori infection is a quadruple therapy of proton pump inhibitors (omeprazole, rabeprazole, etc.) + bismuth agent + two antibacterial drugs. Antibacterial drugs mainly include amoxicillin, clarithromycin, metronidazole, tetracycline, furazolidone and levofloxacin. Some studies have pointed out that according to the local bacterial resistance situation, a suitable radical cure plan can be formulated, and the first radical cure rate can be as high as 90%. However, with the wide application of antibacterial drugs, bacteria have developed different degrees of resistance to the above antibacterial drugs, which has gradually reduced the cure rate. Moreover, some special populations also limit the choice of radical treatment options. For example, penicillin-allergic patients are prohibited from amoxicillin, children under 18 years of age are disabled from levofloxacin, tetracycline is prohibited from children under 8 years of age, and G6PD deficiency patients are cautious about furazolidone. Inhibitors can also cause complications such as decreased appetite and osteoporosis. Therefore, the best method for Hp is prevention. How to prevent Helicobacter pylori infection in daily life? A large number of studies from oral hygiene have proved that Helicobacter pylori infection is closely related to lifestyle habits. Its main source of infection is humans, which can be transmitted through the oral-oral route, fecal-oral route and iatrogenic routes. Helicobacter is mainly derived from the transmission of direct relatives. Therefore, it is necessary to correct some unhealthy living habits, while emphasizing that starting from oral hygiene, prevention of Helicobacter pylori infection. 1. Try not to go to unhygienic places to eat and eat out. If the restaurant is not hygienic, especially many roadside stalls, it is easy to cause cross-infection of bacteria, so as much as possible to reduce unnecessary eating out or gathering, it can be greatly reduced Chance of infection. 2. Wash your hands frequently before and after meals. You need to emphasize here that many people may not pay attention to a detail, and only use clean water to wash their hands.
