Helicobacter pylori is a micro aerobic bacterium present in the human stomach, spiral shaped, with flagella, which can survive in the stomach and can cause damage to the human body. So there is more concern about it. H. pylori was discovered in 1982 by Australian scholars Warren and Marshall, and these two scientists also won the Nobel Prize for Medicine in 2005 for this. H. pylori is closely related to many diseases of the digestive system, such as chronic gastritis, peptic ulcer, and even gastric cancer and MALT lymphoma, etc., and H. pylori has been detected in these populations. If H. pylori eradication treatment is carried out, the corresponding morbidity rate is decreasing and the treatment effect is improving, especially peptic ulcer is a very tricky internal disease with a high recurrence rate before. Since the discovery of H. pylori and eradication treatment, the recurrence rate of peptic ulcer has gradually decreased. In other words, the eradication rate of H. pylori has been increased and the recurrence rate of peptic ulcer has been reduced, which is a great benefit for reducing the number of patients and the process of medical treatment, as well as reducing the medical expenses.
