Diagnostic criteria

The cause of CVS has not been determined, there are no diagnostic tests for CVS. Several other medical conditions 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 may be appropriate.

There are established criteria to aid diagnosis of CVS, essential criteria are

• A history of three or more periods of intense, acute nausea, and unremitting vomiting lasting hours to days
• Intervening symptom-free intervals, lasting weeks to months
• Exclusion of metabolic, gastrointestinal or central nervous system structural or biochemical disease e.g. individuals with specific physical causes (e.g. intestinal malrotation)
