What causes abdominal pain around the navel in children?

Common causes of periumbilical pain in children include gastrointestinal infections, intestinal colic, umbilical hernia, and intussusception. Gastrointestinal infection is the most frequent cause, often resulting from improper diet, consumption of contaminated water, or spoiled food. Intestinal colic is caused by gas or fecal impaction in the intestines, typically accompanied by symptoms such as abdominal distension and difficulty with bowel movements. An umbilical hernia occurs when part of the intestine or an abdominal organ protrudes through a weakness in the abdominal wall at the navel, leading to pain and a noticeable lump. Intussusception is a common pediatric gastrointestinal emergency that may result in intestinal ischemia and necrosis, requiring prompt medical attention and treatment.
