Overview

Cyclic vomiting syndrome (US English) or cyclical vomiting syndrome (UK English) (CVS) is a condition whose symptoms are recurring attacks of intense nausea, vomiting and sometimes abdominal pain and/or headaches or migraines. CVS can affect both children and adults. It was first described in the 19th century with one of the earliest references being that of Samuel Gee in 1882. Onset of the condition is possible at any age but is seen to occur more often in a young age. Why anyone develops it is not clear since it is of unknown etiology. There is a strong suggestion of maternal inheritance. A background of migraines could also be the cause of Cyclic Vomiting Syndrome.
