Many parents get frazzled when their child has a tummy ache or vomiting. The first thing you should do is to identify the cause and then treat it. The first thing to determine is based on age. If the child is under one year old, the tummy ache and vomiting may be due to intussusception. The child’s stool may be green and the child is around three years old mostly due to intestinal spasms. In the case of preschoolers, it may be caused by intestinal roundworms or by vegetative nerve disorders. If the pain is so severe that the child does not dare to move, it is usually due to acute inflammation and should be seen by a doctor immediately, such as acute appendicitis. If the pain is colic-like, it is usually caused by a roundworm or a urinary tract stone. Perforated internal organs can cause tearing pain in the child. When pain occurs in a child, medication should not be used blindly to avoid masking the condition. The location of the pain varies from disease to disease. If the child has pain throughout the abdomen, it is most often caused by a lesion or perforation of an organ. If the pain is around the belly button, it may be due to a disease in the small intestine. Parents should pay attention when their child has abdominal pain, nausea and vomiting, and take the child to the hospital for examination in time.
