Abstract
Background: Cyclic vomiting syndrome is a chronic disorder of gut‐brain interaction that is present in both adults and children. It is characterized by severe nausea, vomiting, abdominal pain, and several non‐GI symptoms. It is also associated with several comorbid conditions such as anxiety and depression, which affect overall health care outcomes.Methods: This article delineates treatment principles, encompassing both abortive interventions and prophylactic regimens currently recommended for CVS. However, it underscores a critical concern: the absence of FDA‐approved medications for CVS treatment, with existing therapies relying on retrospective and open‐labeled trials.Key results: This article emphasizes the pressing need for the development of CVS‐specific outcome assessment tools to facilitate more accurate evaluation and robust data collection for the future studies. In exploring this deficiency, the manuscript also presents the up‐to‐date data and development that enhances our comprehension of patient‐centric concepts, and the challenges faced in creating CVS‐specific tools, and presents a roadmap for their development. Addressing this gap is crucial for advancing our understanding of CVS and optimizing patient care.Conclusions and Inferences: This elucidates the current state of CVS management but also advocates for a future where tailored tools enhance our ability to measure and improve the outcomes for individuals with this debilitating disorder.
