Cyclic vomiting syndrome (CVS) is usually seen in children. The attacks of vomiting often stop as the child gets older, but then they usually go on to develop migraine headaches. A recent report in Headache describes three adults with CVS. The article also mentions a previous report which described another 17 adults with this syndrome.
CVS typically consists of recurrent stereotypical attacks of incapacitating nausea and vomiting, separated by symptom-free periods. Supporting evidence that helps diagnose this condition include personal or family history of migraine and other symptoms, such as headaches, motion sickness, and sensitivity to light.
Just like in children, CVS in adults is a diagnosis of exclusion, meaning that other causes of vomiting must be considered and ruled out. I mentioned in a previous post that one out of three children with CVS turned out to have another medical problem rather than migraine.
CVS in adults seems to respond well to an injection of sumatriptan (Imitrex). This allows for a quick relief of symptoms and makes this debilitating condition very manageable. Besides Imitrex injections, Zomig (zolmitriptan) nasal spray can sometimes be effective as well.
