Cyclic vomiting syndrome (0)

Cyclic vomiting syndrome (US English) (CVS) is a condition whose symptoms are recurring attacks of intense nausea, vomiting and sometimes abdominal pain and/or headaches or migraines. Cyclic vomiting usually develops during childhood usually ages 3–7; although it often remits during adolescence, it can persist into adult life.
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, especially when the family history is significant for a mother with migraines. Persons who suffer from migraines in some cases also have cyclic vomiting syndrome. CVS can be a very painful and uncomfortable syndrome. It results in lack of sleep, abnormal eating, and lack of concentration. Going to school or work can be very hard and painful.
The average age at onset is 3–7 years, but CVS has been seen in infants who are as young as 6 days and in adults who are as old as 73 year. Typical delay in diagnosis from onset of symptoms is 2.7 – 3 years. Females show a slight predominance over males; the female-to-male ratio is 57:43. CVS occurs in all races but seems to disproportionately affect whites.
