Insights
Cyclic vomiting syndrome (CVS) is a functional gastrointestinal disorder affecting both children and adults. This review highlights recent findings on CVS diagnosis, management, and its link to migraine therapies.
Area of Science:
- Gastroenterology
- Neurology
Background:
- Cyclic vomiting syndrome (CVS) is a debilitating functional gastrointestinal disorder.
- CVS is characterized by recurrent, severe vomiting episodes interspersed with symptom-free intervals.
- Once considered primarily a pediatric condition, CVS is increasingly diagnosed in adults.
Purpose of the Study:
- To summarize current knowledge on CVS prevalence, diagnosis, and management in pediatric and adult populations.
- To highlight recent advancements in understanding CVS pathophysiology and therapeutic strategies.
- To present best practices and novel treatments for CVS based on expert consensus and literature review.
Main Methods:
- Comprehensive literature review of recent studies on Cyclic Vomiting Syndrome.
- Analysis of expert consensus on CVS diagnosis and management.
- Synthesis of data on comorbidities, mechanisms, and therapeutic avenues for CVS.
Main Results:
- CVS recognition has increased in adults over the past decade.
- CVS shares a common pathway with migraines, responding to similar therapies.
- New comorbidities, mechanisms, and potential treatments for CVS are emerging.
Conclusions:
- Despite improved recognition, CVS remains a functional gastrointestinal disorder lacking a defined pathophysiology and biomarker.
- The link between CVS and migraines suggests shared neurological pathways.
- Ongoing research is expanding therapeutic options and understanding of CVS.
Purpose Of Review:
Cyclic vomiting syndrome (CVS) is a disabling functional gastrointestinal disorder characterized by severe vomiting episodes that alternate with symptom-free periods. The purpose of this review is to summarize current knowledge and highlight most recent data on prevalence, diagnosis, management, and impact of CVS in children and adults.
Recent Findings:
Originally thought to be a pediatric disorder, the past decade has witnessed a considerable increase in CVS diagnosed in adults. Despite improved recognition of CVS, without a delineated pathophysiology and specific biomarker, it remains classified as a functional gastrointestinal disorder. Migraines and CVS share a common pathway based on several studies and response to migraine therapy. Recent work has begun to expand the list of comorbidities and identify plausible mechanisms and new therapeutic avenues. This review seeks to highlight best practices and novel therapies for CVS based on expert consensus and review of available literature.

Cyclic Processes And Isolated Systems
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
