There are many potential causes of recurrent abdominal pain and/or vomiting in children. If your child is having one or both of these symptoms, you should talk to your doctor so that they can determine the underlying cause.

Although there is a group of disorders called childhood periodic syndromes that can be associated with recurrent vomiting and/or abdominal pain, it is always necessary to first exclude other possible causes such as gastrointestinal disorders. After excluding other medical causes, your physician might determine that the cause of your child’s recurrent vomiting or abdominal pain is in fact a childhood periodic syndrome. Abdominal migraines are associated with periodic abdominal pain and vomiting, whereas cyclic vomiting syndrome is usually characterized by periodic vomiting episodes4.
