Moreover, individuals may be unwilling to disclose their cannabis use to physicians or be unaware of the emetic effects of cannabis, leading to misdiagnosis and underreporting of CHS. Therefore, there is a lack of recognition and knowledge of what are the stages of chs the syndrome by sufferers and physicians. Since 2004, doctors have identified key symptoms and characteristics of the condition that can help speed up diagnosis.
- The CB1 and CB2 receptors function as G-protein coupled receptors that act by inhibiting adenylate cyclase 7.
- This article may discuss unlabeled or investigational use of certain drugs.
- As per her doctor’s recommendation, she set cannabis aside and within a few weeks, she made a full recovery.
- When cannabinoids bind with brain receptors, they tend to prevent nausea and vomiting.
- The best and only way to prevent or reduce your risk for CHS is to avoid or quit marijuana use.
- Scientists do not know much about the function of the CB2 receptors.
How is cannabinoid hyperemesis syndrome treated?
A 2017 report published in the journal German Medical Science showed that 60 percent of people with the disorder reported that hot bathing reduced CHS symptoms. Cannabis Hyperemesis Syndrome (CHS) is a rare but important condition that can affect long-term, frequent cannabis users. It manifests through recurrent episodes of severe nausea, vomiting, and abdominal pain. While cannabis is widely recognized for its therapeutic benefits, including its antiemetic (anti-nausea) properties, CHS represents a unique and paradoxical response in a small subset of users. Understanding CHS can help individuals make informed decisions about their cannabis use and maintain their overall well-being. The mechanism by which cannabis induces hyperemesis is presently unknown.
How can I prevent cannabinoid hyperemesis syndrome?
- In humans this is carried out largely by the CYP2C isoenzyme subfamily of the cytochrome P450 complex 19.
- If you have cannabinoid hyperemesis syndrome (CHS), the best treatment is to stop using weed, even if you’ve been doing it for years with no previous side effects.
- Additional treatments are needed and efforts to discontinue cannabis abuse are paramount.
- At time of writing, the patient had gone 20 months without requiring hospitalization; however, he had a recent relapse of marijuana use and subsequently required hospitalization.
- Not surprisingly, the early identification of patients with CHS leads to a reduction in morbidity and costs 6.
Furthermore, some authors have reported referring patients to drug rehabilitation programs in an attempt to raise the likelihood of long-term cannabis cessation 54,71. Studies have demonstrated the efficacy of outpatient treatment options such as cognitive behavioral therapy and motivational enhancement therapy for marijuana dependence 73. Patients with CHS usually remain misdiagnosed for a considerable time period. In one case series the average number of emergency room visits (7.1 ± 4.3) prior to diagnosis and the delay in diagnosis (for up to 9 years) was substantial 62. Not surprisingly, the early identification of patients with CHS leads to a reduction in morbidity and costs 6. The differential diagnosis of nausea and vomiting is extensive and includes a broad range of pathologic conditions affecting the gastrointestinal tract, the peritoneal cavity, CNS, as well as endocrine and metabolic functions 63.
What Is Cannabinoid Hyperemesis Syndrome?
The metabolism of anandamide is principally carried out via fatty acid amide hydrolase (FAAH), whereas the major enzyme metabolizing 2-AG is monoacylglycerol lipase (MAGL) 18. Two distinct cannabinoid receptors, CB1 and CB2, have been identified in human and animal models. The CB1 and CB2 receptors function as G-protein coupled receptors that act by inhibiting adenylate cyclase 7. In the brain, CB1 receptors are localized to the cerebral cortex, hypothalamus, anterior cingulate gyrus, hippocampus, cerebellum, and basal ganglia 8. In the gastrointestinal system, CB1 receptors are found on both intrinsic and extrinsic neurons, with the enteric nervous system serving as the major site of action 9. Other organs where CB1 receptors have been identified are the spleen, heart, liver, uterus, bladder, and vas deferens 10.
When to seek medical help for cannabinoid hyperemesis syndrome
Cannabinoid hyperemesis syndrome (CHS) is a rare problem that causes constant vomiting. Incorporating cognitive-behavioral therapies encompassing stress management techniques, relaxation exercises, and coping strategies can complement pharmacological interventions in addressing the cyclical nature of CHS and assisting patients in navigating the emotional toll of their symptoms. The profuse vomiting and potential dehydration inherent in CHS often mandate intravenous fluids administration to correct electrolyte imbalances and sustain hydration levels. Adequate fluid resuscitation is crucial during the acute phase of CHS to avert complications and ensure physiological stability. The fundamental and definitive treatment for CHS involves ceasing cannabis consumption. Patients must be informed that habitual cannabis use can Sober living house result in cannabinoid accumulation in adipose tissue, leading to prolonged or recurrent symptoms that may take weeks to completely resolve.
Pharmacology of Cannabinoids
- Another reason is that CHS symptoms and stages are quite similar to those of other conditions, such as cyclical vomiting syndrome.
- People who use marijuana long-term — typically for about 10 to 12 years — are at risk of developing CHS.
- As long as you don’t use marijuana, your symptoms shouldn’t return.
- The only treatment known to cure CHS is to stop using cannabis and not resume its use.
- The hot temperature affects a part of the brain called the hypothalamus, which regulates temperature and throwing up.
CHS has several phases, which have been classified as preemetic, hyperemetic, and recovery.9,16 The preemetic phase, which can last for months to years, is characterized by nausea, fear of vomiting, and abdominal discomfort. Commonly, cannabis users increase their cannabis intake during the preemetic phase in an effort to alleviate nausea.11 During the hyperemetic phase, which typically lasts 24 to 48 hours, the patient experiences frequent nausea and vomiting that is severe in nature. This may lead to weight loss and acute dehydration, potentially resulting in prerenal failure.17,18 The persistent nausea and vomiting can cause electrolyte abnormalities to develop. In clinical practice CHS is most often confused with cyclic vomiting syndrome (CVS). In fact patients with CHS are often mislabeled as having CVS and vice versa.
How soon after cannabis hyperemesis syndrome treatment will I feel better?
In animal studies mice lacking CB1 receptors demonstrate enhancement in circadian HPA axis activity peaks and impairment in glucocorticoid feedback 39. It’s important to be honest about your marijuana use if you have symptoms of CHS. Without knowing this background, providers often misdiagnose CHS as other conditions, like cyclic vomiting syndrome (CVS). The only way to stop CHS and its symptoms is to completely quit using cannabis.
