Cyclic Vomiting Syndrome is an unexplained disorder of children and adults that was first described by Dr. S. Gee in 1882. The condition is characterized by recurrent, prolonged attacks of severe nausea, vomiting and prostration with no apparent cause. Vomiting occurs at frequent intervals (5-10 times an hour at the peak) for hours to 10 days (1-4 most commonly). The episodes tend to be similar to each other in symptoms and duration and are self-limited. The person returns to their normal health between episodes......

Episodes may begin at any time, but often start during the early morning hours. There is relentless nausea with repeated bouts of vomiting or retching. The person is pale, listless and resists talking. They often drool or spit and have an extreme thirst. They may experience intense abdominal pain and less often headache, low grade fever and diarrhea. Prolonged vomiting may cause mild bleeding from irritation of the esophagus. One mother aptly described her child's state as a "conscious coma". The symptoms are frightening to the person and family and can lead to severe dehydration and electrolyte imbalance.
