The cause of CVS is still a mystery. Similarities to migraine suggest a common cause, but as yet no firm evidence has surfaced. Patients can usually identify some factor that precedes an attack. Vomiting can be protracted and lead to complications such as dehydration, chemical imbalances, tearing and burning, and bleeding of the esophagus (swallowing tube). Between attacks, there is no sign of any illness.
