An introduction to Cyclical Vomiting Syndrome and the CVSA, the UK Charity supporting sufferers.
CVS is a poorly understood condition affecting children and adults. Although they have healthy periods in-between, they endure regular episodes of unrelenting intense nausea and vomiting. Episodes can last from days, or in extreme cases weeks. Vomiting can be up to 6 times per hour during this time. CVS is a socially, educationally and physically disabling condition.
