What are the Symptoms of CVS?

The main symptoms of CVS are severe vomiting, nausea, and retching (gagging).  Episodes usually begin at night or first thing in the morning and may include vomiting and retching as often as 6 to 12 times an hour during the worst of an episode.  The episodes are often preceded by thick saliva, which often signifies that an episode is about to occur.

Why is CVS hard to diagnose?

CVS is hard to diagnose because no clear tests--such as x-rays and blood tests--exist to detect it. A doctor must diagnose CVS by looking at symptoms and medical history and by ruling out other more common diseases that can cause nausea and vomiting.

The Treatment of CVS.

CVS cannot be cured.  Treatment varies, but people with CVS are encouraged to get plenty of rest and sleep. Sometimes, though not often, medication can prevent an episode before it starts or alleviate an episode while it is occurring.  Medication can also be given during the symptom free episode in hopes to prevent more episodes from occurring, but they are not always successful.
