What are the causes of abdominal pain around the navel in children?

Children's periumbilical pain may have several possible causes: 1. Intestinal spasm: When children are exposed to environmental stimuli or consume cold foods, intestinal spasms may occur, causing pain around the navel. 2. Irritable bowel syndrome: Caused by increased organ sensitivity or impaired gastrointestinal motility, this condition may be accompanied by symptoms such as nausea, vomiting, and constipation. 3. Intestinal parasitic infection: Poor hygiene or unhealthy lifestyle habits may lead to parasitic infections, causing abdominal tenderness, mainly around the navel, and possibly accompanied by chronic diarrhea. 4. Lymph node infection: The lymphatic system is relatively developed in childhood. When affected by viral or bacterial infections, the lymphatic system may exhibit hyperplasia, leading to swollen lymph nodes and abdominal pain.
