What is the prevalence of Cyclic vomiting syndrome?

How many people does Cyclic vomiting syndrome affect? Does it have the same prevalence in men and women? And in the different countries?


Cyclic vomiting syndrome (CVS) is a rare disorder characterized by recurrent episodes of severe vomiting, often accompanied by nausea and abdominal pain. The exact prevalence of CVS is difficult to determine due to underdiagnosis and misdiagnosis. However, studies suggest that CVS affects approximately 1-2% of the population, with a slightly higher prevalence in children than in adults.

CVS is more common in individuals with a family history of migraines or CVS itself. It typically starts in childhood, with many patients outgrowing the condition by adolescence or early adulthood. However, some individuals may continue to experience episodes throughout their lives.

Episodes of CVS can be triggered by various factors, including emotional stress, infections, certain foods, and sleep disturbances. The episodes usually follow a pattern, with a prodrome phase (early symptoms), a vomiting phase, and a recovery phase. The frequency and duration of episodes can vary greatly between individuals, ranging from a few episodes per year to several episodes per month.

Early diagnosis and proper management are crucial in improving the quality of life for individuals with CVS. Treatment options may include lifestyle modifications, medications to prevent or alleviate symptoms, and supportive care during episodes. It is important for individuals with CVS to work closely with healthcare professionals to develop an individualized treatment plan.

In conclusion, while CVS is a relatively rare condition, it can significantly impact the lives of those affected. Increased awareness and understanding of CVS are essential for timely diagnosis and appropriate management.

I've read that it's more prevalent in women than men and actually affects children more than adults. It's considered a rare disease, yet you can easily find others who also suffer from it.

It isn't quite known because there is a lot of people who likely don't know they have it.

I am not sure about that. THere is a difference between child-onset and adult-onset. I heard that slighly more women have it and it often starts in childhood, but not always. It was thought children grew out of it, but that is not the case for all

Experts don’t know how common cyclic vomiting syndrome is in adults. However, experts believe that cyclic vomiting syndrome may be just as common in adults as in children. Doctors diagnose about 3 out of 100,000 children with cyclic vomiting syndrome every year and only 1 in 200,000 adults.
