Infantile intussusception may present with paroxysmal abdominal pain, abdominal mass, bloody stool and other symptoms. 1. Paroxysmal abdominal pain: When infants suffer from intussusception, it may cause paroxysmal abdominal pain. However, as infants cannot express clearly in words, they may cry and be restless when in pain, so parents need to pay attention to observation. 2. Abdominal mass: As intussusception can occur when the small intestine is trapped into the surrounding organs, intestines and other tissues, the symptom of abdominal mass may appear. 3. Bloody stools: If small intestine necrosis occurs in infants and young children with intussusception, it may lead to jam-like bloody stool symptoms. In addition, infantile intussusception may be accompanied by fever, vomiting, abdominal distension or abdominal tension. If infants and young children have similar symptoms of intussusception, they should go to the hospital in time for treatment.
