Navigating the Intricacies of Cannabinoid Hyperemesis Syndrome CHS: Understanding the Unseen Challenges

Despite this trend, a strict criterion for the diagnosis of CHS is lacking. Early recognition of CHS is essential to prevent complications related to severe volume depletion. The recent body of research recognizes that patients with CHS impose a burden on the healthcare systems. Understanding the pathophysiology of the endocannabinoid system (ECS) remains central in explaining the clinical features and potential drug targets for the treatment of CHS. The frequency and prevalence of CHS change in accordance with the doses of tetrahydrocannabinol and other cannabinoids in various formulations of cannabis. CHS is unique in presentation, because of the cannabis’s biphasic effect as anti-emetic at low doses and pro-emetic at higher doses, and the association with pathological hot water bathing.

Immediate Management of CHS

Over time, these receptors may become overactive, leading to the severe nausea and vomiting experienced by people with CHS. Although cannabis typically reduces nausea, in CHS, it has the opposite effect, causing symptoms to worsen. Cannabinoid hyperemesis syndrome is an uncommon reaction to cannabis use. In addition to frequent and severe vomiting, patients may have difficulty eating and drinking, and only find (temporary) relief in hot showers and baths. Cannabinoid hyperemesis syndrome (CHS) is a very unpleasant — and potentially dangerous — complication of long-term marijuana use.

Deterrence and Patient Education

If you’re not totally sold on abstinence quite yet, Walker says some people find temporary relief from symptoms through hot showers or baths. If your vomiting, nausea or abdominal pain are constant or severe, bypass the visit with your primary care doctor entirely and go straight to the emergency department. To make a diagnosis, your healthcare provider will conduct a thorough physical examination and ask you about your past health Halfway house and current symptoms. It’s helpful to volunteer your history of cannabis use with your provider if you are not asked about it.

What Are the Health Complications of CHS?

Cannabis can be addictive, and people who stop using it can experience symptoms not unlike opioid or alcohol withdrawal, said Dr. Deepak Cyril D’Souza, director of the Yale Center for the Science of Cannabis and Cannabinoids. Decades ago, most people had less opportunity to consume cannabis in daily life. “No kid could use continuously throughout the day and also be doing anything else, because they would have chs syndrome been smoking a joint before,” she said. When Dr. Deepa Camenga began her career about 20 years ago, she rarely if ever saw pediatric patients with CHS, she said. Today, hospitals in her area around New Haven, Connecticut, see pediatric CHS cases nearly every day, she added. What was causing this intense stomach pain, Brittany wondered as she rode in an ambulance one late night in February.

• Although there was some limited evidence that the medication reduces large intestine contractions, results on pain relief have been mixed.
• The hot temperature affects a part of the brain called the hypothalamus, which regulates temperature and throwing up.
• Experimental evidence reveals that when pesticides are employed in cannabis culture, up to 70% of their concentration may be recruited into its smoke (Sullivan et al., 2013).
• Typical antiemetics such as ondansetron, commonly known as Zofran, have often been found ineffective at suppressing nausea caused by CHS.
• Hypothetically, analogous metabolomic testing of CHS patients may provide additional elucidation of its pathophysiology and highlight possible future approaches to its treatment.
• Researchers aren’t sure exactly why weed causes CHS symptoms only in some people.

How Common Is CHS?

Prevalence cannot accurately be determined until accurate diagnosis and classification are agreed upon. Most studies regarding the epidemiology of CHS lack information about patient histories, comorbid psychiatric illnesses, possible re-disposing factors, and type of cannabis consumed (i.e. THC percentage), which may aid the understanding of the etiology of CHS. If you are experiencing severe vomiting or other concerning symptoms, contact your health care provider. As many other health problems could lead to repeated vomiting, it’s important to discuss your complete health history, including your cannabis use, with any provider you see for your symptoms.

History and Physical

• Education regarding the potential effects of long-term high doses of cannabinoids should be disseminated to physicians and the public to better detect and manage this debilitating syndrome.
• If you have CHS and don’t stop using, your symptoms like nausea and vomiting are likely to come back.
• This underscores the critical need to correlate symptoms with cannabis consumption, ruling out overlapping diagnoses that could be mistaken for CVS.
• You’ll stay in the hospital until you can hold down regular meals and your vomiting subsides.
• It was so bad she thought it might be a recurrence of her severe pancreatitis, the illness for which she once had been hospitalized and put on life support.

This results in the persistent vomiting and nausea characteristic of CHS. With cannabis use on the rise, awareness of hyperemesis cannabis syndrome must increase. Better education can help people recognize symptoms early and seek treatment, improving outcomes and reducing healthcare burdens. If you suspect CHS, consulting a healthcare professional can guide you toward effective management and support.

In select cases, topical application of capsaicin cream on the abdomen has demonstrated promise in alleviating CHS symptoms. Capsaicin, the active compound in chili peppers, acts on TRPV1 receptors, potentially modulating gastrointestinal sensory pathways and altering intestinal blood flow to provide relief from nausea and vomiting. The vasodilation induced by heat exposure in hot showers can enhance peripheral blood vessel dilation, promoting improved circulation.

With the continued use of cannabis and a lack of treatment, symptoms become more intense. The only treatment known to cure CHS is to stop using cannabis and not resume its use. Cannabinoid hyperemesis syndrome (CHS) is a rare problem that causes constant vomiting. Cannabinoids are found in the cannabis plant and bind to cannabinoid receptors found in our brains, gastrointestinal tracts and immune cells. Cannabinoids include tetrahydrocannabinol (THC), cannabidiol (CBD) and cannabigerol (CBG). While symptoms can be managed, the only way to stop CHS for good is to quit using cannabis in any form.
