Pain around the umbilicus in children is a common clinical symptom in pediatrics. There are many causes that can cause pain around the umbilicus, most often seen clinically in disorders of the small intestine, ranging from indigestion, to enteritis, to intestinal worms, and so on. Small intestinal disorders: such as ascariasis, intestinal obstruction, enteritis, peritonitis, mesenteric lymphadenitis, abdominal allergic purpura, and other such disorders can cause symptoms of peribulbar pain. Stomach pain: Some children are not able to express the specific pain site, so stomach pain cannot be completely excluded. Periumbilical infection and umbilical hernia: Inflammatory infection of the pediatric belly button and umbilical hernia can also cause periumbilical pain. Finally, appendicitis should also be taken seriously. Although appendicitis typically manifests as right lower abdominal pain, appendicitis in children is often not typical enough and the child’s ability to express itself varies from person to person, so it is important to pay attention to the presence of a surgical disease like appendicitis even if it is periumbilical pain. In conclusion, children with periumbilical pain are mostly associated with inflammation, obstruction, spasm and intestinal parasites in the abdominal organs. It is recommended to pay attention to the establishment of normal and healthy eating habits, timely consultation for abdominal examination to clarify the cause and treat for the cause, and for unexplained abdominal pain, remember not to use painkillers casually to cover up the condition and delay treatment.
