Cyclic vomiting syndrome causes bouts of severe nausea and vomiting that can last for days. The disorder, which has no known cause, may affect as many as one in 50 children. Once thought to affect primarily girls, cyclic vomiting syndrome is now believed to affect boys and girls equally.

Symptoms typically begin between the ages of 3 and 7 years. Children tend to outgrow cyclic vomiting syndrome when they are teenagers. While the disorder occurs most often in children, cyclic vomiting syndrome can begin at any age. Adult episodes tend to occur less often than they do in children, but they usually last longer.

Cyclic vomiting syndrome appears to be linked to migraines in some cases. Treatment with migraine medications often helps.
