Abdominal pain can occur during a child’s development, but the causes of abdominal pain vary from age to age and from child to child. As a parent, it is very important to know how to distinguish what causes abdominal pain for the sake of your child’s health. First of all, for infants and toddlers, their abdominal pain is often colic-based, and children at this stage, because they cannot express not with words, tend to cry to show the pain. As the baby grows up, colic will ease and disappear, at which point the baby will no longer cry. Secondly, infants and young children within 2 years of age are prone to symptoms of intussusception, which are typically characterized by: abdominal pain, abdominal masses, and bloody stools. In addition to paroxysmal crying, the child may also vomit, and the baby may curl up in pain. Also, hernia is a cause of abdominal pain in infants and children. As a parent, you need to pay attention to see if there is a swelling bulging up in the groin and scrotum area when the baby cries, and if a pediatric hernia occurs, you should go to the hospital as soon as possible. Abdominal pain in childhood, we most commonly see acute gastroenteritis, intestinal cramps, allergic purpura and pediatric acute appendicitis. Some children with respiratory infections also complain of stomach pain, which is often due to mesenteric lymphadenitis. Parents should pay attention to their babies’ personal hygiene, train their children to have a good diet, and observe their babies’ discomfort. If the abdominal pain is frequent, if the abdominal pain is accompanied by vomiting, diarrhea and fever, or if the abdominal pain is severe, you need to seek medical treatment in time.
