• The relationship between migraines and CVS is unclear, but many children with CVS experience migraines or have a family history of migraines. 
  • Chronic marijuana use is also associated with CVS
    •  Chronic marijuana use leads to a condition called hyperemesis syndrome, which leads to persistent vomiting.
  • To rule out hyperemesis syndrome, you must stop using marijuana for at least one to two weeks and observe if the vomiting decreases.
  • Additionally, individuals who are prone to get motion sickness are at risk for CVS
