Cyclic vomiting syndrome may affect children more often than adults. Some affected children outgrow these episodes as they get older but for many others, CVS transitions into migraine headache. Oftentimes, nausea is the most disturbing symptom, more so than vomiting. Additional symptoms often present during an episode including dizziness, paleness of the skin (pallor), lack of energy (listlessness) and, abdominal pain and headaches. The associated nausea and vomiting can be severe enough to incapacitate the individual who may be unable to walk or talk and/or be bedridden. For each person who suffers from this condition, the episodes are similar to each other. This alternating pattern of disease and disease-free periods distinguishes cyclic vomiting syndrome from other gastrointestinal disorders. Some can experience milder symptoms between attacks. An episode may last for a few hours to several days and is then followed by a period of time during which affected individuals are relatively free of severe nausea and vomiting.
