Infants and young children infected with H. pylori can first observe the baby’s symptoms and choose whether or not to take medication depending on the severity. If an infant or young child infected with H. pylori does not show any adverse symptoms, such as indigestion, acid reflux, abdominal pain, etc., and no one else in the family shows symptoms of H. pylori infection, no measures can be taken first and close observation can be observed. If infants and young children infected with H. pylori have the above mentioned uncomfortable symptoms, they should go to the hospital immediately for examination and medication after diagnosis, usually taking triple therapy including amoxicillin, ornidazole, omeprazole and so on. Note that the use of medication must follow the doctor’s instructions, do not use the drug arbitrarily. After the diagnosis is confirmed, it is also necessary to pay attention to whether family members have similar symptoms to prevent cross-infection. At the same time, pay attention to the diet of infants and young children, avoid eating irritating food, and do not take drugs.
