Miss Lee, who got the medical report, was nervous about the “positive” result of the H. pylori test. “I heard that H. pylori can cause stomach cancer, is not very dangerous?” She was full of anxiety to ask. For Ms. Lee such doubts are not uncommon, today on this common Helicobacter pylori some simple science. ”Helicobacter pylori” was discovered in 1982 by two Australian scholars, referred to as Hp. The medical community believes that H. pylori infection is one of the main causative factors of peptic ulcers, gastric mucosa-related lymphoid tissue lymphoma and gastric cancer. According to the clinical epidemiological survey, Hp infection is distributed worldwide, with a wide range of infection and a high infection rate, and its incidence ranks second only to dental caries. The rate of Hp infection in our general population is as high as 50% to 80%, which is a highly infected country. However, the vast majority of people have been clinically asymptomatic despite carrying Hp in their stomach for life, which is called the carrier state or carrier of Hp, and develops on specific conditions and individuals. Nowadays, many medical institutions have added the H. pylori screening program to their medical checkup packages to see if the examinee is carrying H. pylori in his or her body through tests such as blood sampling or blowing. In fact, not all people infected with H. pylori must receive treatment. The general population in China is infected with H. pylori up to 50% to 80%, but only about 1/3 of these so-called “carriers” need to be treated. ”For example, if you are infected with H. pylori and also suffer from gastric ulcer, erosive gastritis, or have a family history of gastric cancer, or are particularly panicky. Otherwise, over-treatment can have other negative consequences.” Generally speaking, people with no symptoms and no high-risk factors do not need medication, and drug abuse may lead to more troublesome drug-related hepatitis. Most H. pylori carriers do not need treatment, but there are four types of infected people who need treatment: first, patients with peptic ulcers or other related gastric diseases; second, patients with erosive gastritis; third, parents, siblings and other immediate family members with gastric cancer infection, H. pylori may increase the risk of gastric cancer; fourth, patients who are psychologically particularly fearful of Hp, can be treated appropriately to relieve tension, on Fourthly, for patients who are psychologically panic about Hp, they can be treated appropriately to relieve the tension and to relieve the stomach symptoms. For the above four types of patients, doctors will recommend Hp eradication treatment. In fact, the treatment process for H. pylori is not complicated. Many patients take the medication for 10-14 days and are cured. After Hp eradication, it is also beneficial for the prevention of gastric cancer. Of course don’t forget to check regularly for recurrence.
