Experts also aren’t clear on what causes CHS, or why some people develop it while others don’t. Since it was first identified in 2004 in Australia, researchers have looked at the effects of cannabis on the vomiting centers of the brain. This means that getting diagnosed could be key to preventing other health risks for this vulnerable population. After halting cannabis use patients typically recover in a matter of days, weeks, or months. Nausea ceases, appetite resumes, body weight is regained, and bathing/showering regimen returns to normal. Heard says pediatric cases are down, however, thanks to steps the Colorado marijuana industry has taken, some by force of legislation, in packaging and individual dosing.
- What has never been clear was why only some heavy users of cannabis seem to be affected.
- If you have a medical problem, please contact a qualified health professional.
- Rimonabant, a CB1 antagonist, blocks the appetite stimulating qualities of the cannabinoids in the hypothalamus and has been marketed for the treatment of obesity and metabolic dysfunction 34.
- In comparison, much less is known about the effects of the CB2 receptor.
- If you need help quitting, speak to a healthcare provider or connect with your local addiction treatment services.
- In the brain, CB1 receptors are localized to the cerebral cortex, hypothalamus, anterior cingulate gyrus, hippocampus, cerebellum, and basal ganglia 8.
Cannabis hyperemesis syndrome: an update on the pathophysiology and management
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. Once you do that, your repeated nausea and vomiting should go away and not return. Since THC is stored in your body fat, it can take weeks to months before all the symptoms go away and you notice a difference. To assess the burden of disease, Meltzer and his colleagues conducted a survey of 1,052 people who report suffering from cannabinoid hyperemesis syndrome. The researchers asked questions about frequency of use, duration of the habit, the age they started using the drug, what is Oxford House and need for emergency department or hospital care.
- Cannabis, derived from Cannabis sativa plants, is a prevalent illicit substance in the United States, containing over 400 chemicals, including 100 cannabinoids, each affecting the body’s organs differently upon ingestion.
- Symptoms of withdrawal can include disrupted sleep, increased heart rate, sweating, irritability and mood swings, according to the Centers for Disease Control and Prevention.
- If you need help quitting cannabis, the Substance Abuse and Mental Health Services Administration offers a 24/7 helpline in English and Spanish.
- The amitriptyline effect on CHS is significantly lowered in patients with continued usage of cannabis products.

This comprehensive review explores the ECS’s involvement, CHS management approaches, and knowledge gaps to enhance understanding of this syndrome. Visits and extensive recurring serum testing and imaging evaluations with increased healthcare-related costs. It is crucial to exclude other entities such as Addison’s disease, migraines, hyperemesis gravidarum, bulimia, and psychogenic vomiting, which can mimic CHS symptoms and may also occur alongside it. A thorough medical history, complete physical examination, and focused diagnostic testing help differentiate from these other differential conditions. CHS is classified as a type of functional gut–brain disorder and a variant of cyclic vomiting syndrome (CVS) per the Rome IV structured framework. Venkatesan et al. 21 described the features of CHS, including clinical features, cannabis use https://ecosoberhouse.com/ patterns, and symptom resolution after at least six months of abstinence, helping differentiate it from CVS.
Hyperemetic Phase
For example, in two recently published series of adult patients with CVS, approximately one third of patients reported daily marijuana use 65,66. Based on the categorization of functional disorders developed by Rome III, chronic marijuana use (CHS) is recognized as a mechanism for nausea and vomiting distinct from CVS 67. Although both conditions share an astonishing similarity, there are several significant differences. For example, CVS patients usually have important psychological comorbidities including depression and anxiety 64,65. In addition, CVS patients have a high prevalence of migraine headaches or a family history of migraines. Furthermore, gastric emptying rates in patients with CVS are often accelerated rather than delayed 46,65.
- During the hyperemesis stage, doctors focus on preventing dehydration and stopping the symptoms of nausea and vomiting.
- However, researchers have yet to determine the cause of CHS since it does not affect all users of marijuana.
- Hot showers improve symptoms of nausea and vomiting 6,52–56,60,62,68,71, abdominal pain 6,56,71, and decreased appetite 68 during the hyperemetic phase.
- Patients are typically young adults with a long history of cannabis use.
When patients are discharged from a UCHealth emergency department, the official diagnosis is typically “vomiting,” though the CHS details are entered into the medical record’s notes. TCAs are anticholinergics that modulate alpha-2-adrenoreceptors, thereby decreasing sympathetic nervous system activity and mitigating brain–gut autonomic dysfunction 95. Amitryptine helps to prevent vomiting cycles in CHS, usually at doses between 50 and 200 mg daily 96. Or hospital, and dosage titration can be made during closer cannabinoid hyperemesis syndrome outpatient care.
