Definition
By Mayo Clinic staffCyclic vomiting syndrome causes bouts of severe nausea and vomiting that can last for days. The disorder has no known cause.
Symptoms of cyclic vomiting syndrome typically begin between the ages of 3 and 7 years. While the disorder occurs most often in children, cyclic vomiting syndrome can begin at any age. Adult episodes tend to occur less often than do episodes in children, but adult episodes usually last longer.
Cyclic vomiting syndrome appears to be associated with migraines in some cases. Most children outgrow cyclic vomiting syndrome when they're teenagers. However, children with this condition are at increased risk of developing migraines.
