HP infection is considered as one of the major causative factors of peptic ulcer, gastric mucosa-associated lymphoid tissue lymphoma and gastric cancer. According to clinical epidemiological surveys, Hp infection is distributed worldwide, with a wide range of infection and a high rate of infection. 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 and generally do not require treatment, despite carrying Hp in their stomachs for life. In fact, not all people infected with HP must receive treatment. In fact, not all people infected with HP must be treated. The general population in China is infected with HP up to 50% to 80%, but only about 1/3 of these so-called “carriers” need to be treated. For example, people who are infected with HP and also suffer from gastric ulcer, erosive gastritis, or have a family history of gastric cancer, or are particularly panicky. Otherwise, over-treatment can lead to other negative consequences. There are four types of infected patients who need treatment: firstly, patients with peptic ulcer or other related gastric diseases; secondly, patients with erosive gastritis; thirdly, infected patients whose parents, siblings and other immediate family members have gastric cancer, HP may increase the risk of gastric cancer; fourthly, patients who are psychologically panic about Hp, they can be treated appropriately to relieve the tension, which can also play a role in relieving the stomach symptoms. For the above four types of patients, doctors will recommend Hp eradication treatment. In fact, the treatment process of HP is not complicated. Most patients can be eradicated by taking the medication for 10-14 days. After eradication of Hp, it is also beneficial for the prevention of gastric cancer.
