Title: Cyclic vomiting syndrome- Pathophysiology, comorbidities, and future research directions
A recent article has called for the establishment of a multicenter registry in order to learn more about cyclic vomiting syndrome and related disorders. Creating such a registry would provide a database of patients for clinical trial recruitment, research on patient outcomes across different treatment methods, the underlying mechanism for the disorder, and the ability to identify potential biomarkers for the disorder. The registry would expand our understanding of the disorder, on all fronts, and hopefully, reveal the most effective treatment method.
Could such a registry be created while still safeguarding patient privacy?
Highlighted in this article is the similarity of cyclic vomiting syndrome and cannabinoid hyperemesis syndrome (CHS). CHS is often misdiagnosed or goes undiagnosed for an exorbitant amount of time. By creating this registry for cyclic vomiting syndrome and related disorders, including CHS, the same information about genetics, underlying mechanisms, and effective treatments could also be determined.
Finding a genetic basis for cannabinoid hyperemesis syndrome would support patients looking into cannabis-based medicine to decide if cannabis would even be an effective treatment, by allowing them to discover possible side effects to which they might be more susceptible.
Some people are concerned that Cannabinoid Hyperemesis Syndrome (CHS,) a rare condition involving cyclical vomiting, may be caused by neem oil or pesticides. However, symptoms are more consistent with an overload of CB1 receptors, circumstances that occur primarily with habitual, large-volume consumers.

“Cannabis hyperemesis syndrome: still under-recognized after all these years“
After two years of chronic vomiting and pain and dozens of trips to emergency rooms a 23-year-old woman was found to have cannabis hyperemesis syndrome (CHS). Physicians are still unable to recognize the early symptoms of CHS as cannabis use is still in a legal gray area in much of the country. A lack of research, recognition, and trust often prevents a quick diagnosis when an illness is related to cannabis, leading to multiple referrals and invasive tests.
CHS was first described 15 years ago yet it is not frequently recognized in patients. The case study featured in this blog post highlights patients and physicians’ outcry for tolerance and support so that cannabis-related illnesses can be efficiently and effectively engaged.
Researchers have found that capsaicin cream is an effective and safe method of treating cannabinoid hyperemesis syndrome (CHS) in adolescents. Capsaicin cream has previously been shown to be effective at treating CHS in adults but adolescents have previously been treated with haloperidol, a drug known to have serious side effects. Capsaicin cream offers a much safer and more cost-effective method of treatment for adolescents.
Association of Marijuana Use and Cyclic Vomiting Syndrome
A recent study has found that a subset of patients diagnosed with Cyclic Vomiting Syndrome actually suffers from Cannabinoid Hyperemesis Syndrome. Cannabinoid Hyperemesis Syndrome is a rare condition that primarily occurs in daily, long-term users of cannabis, more common among males than females. Chronic cannabis consumers should inform their physicians of any illicit drug use, as well as any cannabis consumption, during routine check-ups and/or emergency room visits, to ensure accurate diagnoses can be made.
