Cyclic Vomiting Syndrome (CVS) Print E-mail

Dr. Kennedy Cyclic vomiting syndrome (CVS) is characterized by episodes , bouts, or cycles of severe nausea and vomiting lasting for hours or even days alternating with longer asymptomatic periods with no symptoms. The cause of the syndrome is unknown. Each episode is similar to previous ones and tends to start at about the same time of day, last the same length of time, and present the same symptoms at the same level of intensity. Episodes of CVS can be so severe that a person may have to stay in bed for days, unable to go to school or work. Because other common diseases and disorders can also cause cycles of vomiting, people with the syndrome may initially be misdiagnosed. Cyclic vomiting syndrome affects children more often than adults beginning most commonly between ages 3 and 7. In adults, episodes tend to occur less often but last longer than in children and the events that trigger episodes in adults cannot be pinpointed as easily as they can in children.
