Cyclic vomiting syndrome is a disorder characterized by nausea and vomiting, separated by periods without any symptoms. There is very little research on this field at this point and most doctors do not fully understand the disorder. The goal of this study is to assess how the stomach empties food. Participants will be asked to participate in this study because either (a) they have been diagnosed and/or treated for cyclic vomiting syndrome in the past, or (b) they are physically healthy. The study seeks to compare how a healthy person's stomach empties to how the stomach of someone with cyclic vomiting disorder empties.
