Pediatric intestinal obstruction is an abnormality in the intestinal tract of infants and children, where the intestines may become interlocked or obstructed by certain objects that block the intestines or obstruct peristalsis, preventing the movement and elimination of stool and other contents. Pediatric intestinal obstruction is a relatively common and sudden disease. At the onset of the disease, infants and children will experience abdominal cramps, and because they cannot express themselves verbally, they will exhibit sudden crying and fussing, writhing, stiffening of the limbs and body, and bending of the legs toward the abdomen. If not treated in time, the child may become drowsy and vomit as the condition worsens. Initially, the vomit is undigested food, followed by bile-like objects. Infants and children may also have subsequent bowel movements, starting with normal stool and followed by stool that may contain blood or dark red blood clots. Children with intestinal obstruction must be taken to a doctor promptly, otherwise the condition may worsen and lead to shock or even death. Some children with less severe intestinal obstruction can be treated with fasting and medication, and can be cured after treatment. However, if the child’s intestinal obstruction is more serious, he or she still needs early surgical treatment to avoid complications. After the disease, we should pay attention to the dietary health of children and eat more light foods, fruits and vegetables. Pediatric intestinal obstruction is more urgent and harmful, and should be treated in time, otherwise it will endanger the life and health of infants and children.
