Cyclic vomiting syndrome (CVS) is characterized by recurrent, discrete episodes of nausea and vomiting separated by intervals of normal health.  An underlying cause is often not apparent. Onset is most common during preschool or early school years though CVS may begin at any age, from infancy onward.

Considering the anatomical relationship between the upper cervical spine and the dura, as well as, the link between myodural traction and migraine disorders, it seems reasonable that the chiropractic adjustment of the occiput bone had a direct impact on relieving dural irritation ultimately leading to the resolution of the patient’s cyclic vomiting symptoms.
