Positive H. pylori indicates H. pylori infection in the stomach, which is usually not very serious. In this case, if accompanied by symptoms of the digestive tract, including acid reflux, belching, abdominal distension and other manifestations, or electronic gastroscopy suggests the presence of peptic ulcer or peptic tumor, it is recommended to perform sterilization treatment. The current treatment recommendation is quadruple therapy, mainly two antibiotics plus an acid-suppressing drug plus a bismuth agent, taken orally for 14 days, stopping after 14 days, and rechecking after 1 month of discontinuation to understand whether it is eradicated, because H. pylori more than 50% of the normal population has a co-infection, and is currently considered to be associated with peptic ulcers and tumors, so it needs to be eradicated.
