Are pediatric and adult-onset cyclic vomiting syndrome (cvs) different conditions?

Not entirely: The clinical presentation might be slightly different, especially in terms of triggers (more common with children) , they are not considered different conditions.

Possibly: Cvs in children has much more study behind it than in adults, and therefore, less information to draw from. Recent studies suggest that many of the characteristics of cvs are independent of age. As the cause is still unknown, treatment consists of mainly managing the symptoms. As with all conditions, seek the advice of your physician and internal medicine specialist.
