CVS is Rare
Cyclical vomiting syndrome (cvs) is a diagnosis of exclusion.
It is a rare problem. It has a very typical pattern of severe vomiting
which lasts for less than 48 hours. In between episodes, people are totally fine. Attacks occur every few weeks or months. Acid reflux
, gallbladder and pancreas
disease need to be excluded. Avoid marijuana
- it has recently been implicated as a cause.
