    Vomiting is different from regurgitation, though the terms are often used interchangeably. Regurgitation is the return of undigested food back up the esophagus to the mouth, without the force and displeasure associated with vomiting. The causes of vomiting and regurgitation are generally different.

    Cyclic vomiting syndrome is a chronic functional condition of unknown pathogenesis. CVS is characterized as recurring episodes lasting a single day to multiple weeks. Each episode is divided into four phases: inter-episodic, prodrome, vomiting, and recovery. Inter-episodic phase, is characterized as no discernible symptoms, normal everyday activities can occur, and this phase typically lasts one week to one month. The prodrome phase is known as the pre-emetic phase, characterized by the initial

    There is no known genetic pathogenesis for CVS. Recent studies suggest many affected individuals have a family history of related conditions, such as migraines, psychiatric disorders and gastrointestinal disorders. Inheritance is thought to be maternal, a possible genetic mitochondrial inheritance. Adolescents show higher possible mitochondrial inheritance and maternal inheritance than found in adults. Single base-pair and DNA rearrangements in the mitochondrial DNA have been associated with the

    The cause of CVS has not been determined and there are no diagnostic tests for CVS. Several other medical conditions, such as cannabinoid hyperemesis syndrome, can mimic the same symptoms, and it is important to rule these out. If all other possible causes have been excluded, a diagnosis of CVS using Rome criteria by a physician may be appropriate. Once formal investigations to rule out gastrointestinal or other causes have been conducted, these tests do not need to be repeated in the event of f

    Treatment for cyclic vomiting syndrome depends on the evident phase of the disorder. Because the symptoms of CVS are similar to those of the disease well-identified as "abdominal migraine," prophylactic migraine medications, such as topiramate and amitriptyline, have seen recent success in treatment for the prodrome, and vomiting, phases, reducing the duration, severity, and frequency of episodes. Therapeutic treatment for the prodromal phase, characterized by the anticipation of an episode, con

    Fitzpatrick et al. identified 41 children with CVS. The mean age of the sample was 6 years at the onset of the syndrome, 8 years at first diagnosis, and 13 years at follow-up. As many as 39% of the children had resolution of symptoms immediately or within weeks of the diagnosis. Vomiting had resolved at the time of follow-up in 61% of the sample. Many children, including those in the remitted group, continued to have somatic symptoms such as headaches and abdominal pain. Most children who have t
