Infants and young children infected with Helicobacter pylori, the general situation does not recommend radical treatment.

It is important to cut off the source of infection and reduce the infection rate. 2. If peptic ulcer and gastric MALT lymphoma exist in infants and young children, they must be treated radically. Chronic gastritis, family history of gastric cancer, unexplained refractory iron-deficiency anemia, and planning to take NSAID (including low-dose aspirin) for a long period of time can be selected for radical treatment. It is usually treated with the triple therapy of omeprazole + clarithromycin + amoxicillin. When using these medications for infants and young children, it is important to use them under the supervision of a doctor in strict accordance with medical advice.
