Children as young as 4 years old may not be checked for H. pylori if there are no abnormalities, but it is possible to check for H. pylori in those who have symptoms such as chronic abdominal pain, diarrhea, indigestion, nausea, and vomiting.
H. pylori is a bacterium that parasitizes the stomach, but the symptoms that appear after children are infected with H. pylori are relatively low, and they may have symptoms such as long-term abdominal pain, diarrhea, indigestion, nausea, vomiting, etc. However, some children will not have obvious symptoms even if they are infected with H. pylori.
Therefore, it is recommended that 4-year-old children with abnormalities go to the hospital in a timely manner and, if necessary, undergo testing for H. pylori, such as the carbon 13 or carbon 14 breath test, to determine whether an infection exists.
When infection exists, it is recommended that targeted treatment be provided under the guidance of a doctor.
