Hot baths may relieve the nausea for a while, but they don’t cure CHS. Delay of adequate https://ecosoberhouse.com/ treatment of CVS and CHS patients results in prolonged recovery time and shortened inter-episodic phases of comparative wellness 1, 2. While symptoms begin as mild, they can intensify and increase your risk of severe problems. As a somewhat new problem, CHS is often mistaken for other problems with the same symptoms.
What is cannabis hyperemesis syndrome?
- Drugs with an anticholinergic effect may likewise block medullary mediated vomiting, though they may have minimal impact on visceral stimulation, including the crippling abdominal cramping pain that patients with CHS experience.
- Of those surveyed, 155 met the criteria of smoking cannabis at least 20 days per month.
- After stopping cannabis use, symptoms generally resolve within days or months.
When you use marijuana for many years, it can start to slowly change how the receptors in your body respond to the cannabinoid chemicals. For example, the drug affects the receptors in the esophageal sphincter, the tight band of muscle that opens and closes to let food go from your throat to your stomach. If this flap doesn’t work properly, your stomach acids might flow upward and cause you to have nausea and vomiting. 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). Cannabinoids are compounds in the Cannabis sativa plant that bind to cannabinoid receptors in your brain, spinal cord, gastrointestinal tract and other body tissues.
- Abdominal ultrasound, oesophago-gastro-jejunoscopy including biopsy and gastric emptying speed examination should be performed in all cases of suspicion of CVS and CHS 1, 2.
- These episodes of vomiting are often separated by weeks or months, and there is a return to baseline between episodes.
- It’s possible that what looks like a rise in cases could actually just be a rise in people seeking help and/or a rise in people admitting to their cannabis use.
What happens if cannabis hyperemesis syndrome is left untreated?
Therefore, the available data relies on case reports and case series 1, 2, 3, cannabinoid hyperemesis syndrome 4, 5, 6, 7, 8. The pain is usually around the belly button and can get better with hot shower/baths. Some patients use hot water bags across the center of their belly and can burn the skin if done a lot.

What are the symptoms of cannabinoid hyperemesis syndrome?
The clinical effects of volume depletion dominate complications related to CHS. Reports of severe volume depletion resulting in acute kidney injury and severe electrolyte disturbances with rhabdomyolysis have been reported in the literature 49. Severe and persistent vomiting can also lead to Mallory-Weiss tear 47. Evidence supporting the hypothesis of cannabinoid hyperemesis is weak. The concept of CHS is based on the hypothesis of a paradoxical effect of cannabis (in long-term abuse) due to pharmacodynamical and pharmacokinetic variations in susceptible individuals 2, 5, 6.

ECS and CHS
The overlap in symptoms between CHS and SMA syndrome, especially in a patient previously diagnosed with CHS, can lead to diagnostic delays, which necessitates greater awareness and education for both health care professionals and patients. Previously published studies have highlighted the infrequent but serious results of weight loss due to THC-related nausea 4,5. This report recounts the case of an adolescent girl with symptoms similar to those of her previous episodes of tetrahydrocannabinol-induced hyperemesis, despite a 21-kg weight loss over 6 months.
Can You Treat CHS Symptoms at Home?

Anchoring errors, in contrast, result in clinicians rigidly adhering to initial impressions, even when presented with conflicting data, potentially delaying an accurate diagnosis and timely treatment 6. These cognitive pitfalls demonstrate the intricacies and challenges of medical decision-making and highlight the need for awareness and education among both health care professionals and patients to ensure comprehensive, patient-centered investigations. For our patient, cognitive errors delayed the diagnosis and, hence, initiation of appropriate treatment.
- Taking a hot shower or bath has also been shown to relieve symptoms.
- Many researchers feel that CHS is underrecognized and underdiagnosed.
- I told the doctors about the CHS diagnosis, and tests revealed that his kidneys were shutting down once more.
Haloperidol is traditionally used to treat agitation; however, it has been used successfully as an antiemetic in general surgery and oncology. D2 receptors are also present in the chemoreceptor trigger zone, which may account for these antiemetic properties. Additional studies are warranted to determine haloperidol’s place in therapy and its optimal dosing. This case report seeks to raise awareness of the effects of cognitive errors in clinical practice. This tendency to prematurely attribute symptoms to a known diagnosis and thereby overlook alternative and potentially more accurate explanations can lead to delays in diagnoses and treatments.
- Compulsive hot showering or bathing may be critical in distinguishing CHS from CVS and other conditions with similar symptoms.
- If this flap doesn’t work properly, your stomach acids might flow upward and cause you to have nausea and vomiting.
- Awareness of cognitive error is especially important in the context of the increasing prevalence of legalization of tetrahydrocannabinol/marijuana in several states.
- Differential diagnostic considerations of nausea and vomiting encompass diagnoses from various clinical disciplines (Table 2 (Tab. 2)).
- However, with repeated use in some people, it can have the opposite effect on the digestive tract.
Symptoms and Causes
Additionally, not all cannabis users develop CHS, causing further difficulty in describing the syndrome. Cannabis hyperemesis syndrome (CHS), some hospital workers claim, is on the rise — something they believe is the result of “high potency weed,” according to a report published in July by NBC News. The fundamental and definitive treatment for CHS involves ceasing cannabis consumption. Patients must be informed that habitual cannabis use can result in cannabinoid accumulation in adipose tissue, leading to prolonged or recurrent symptoms that may take weeks to completely resolve. Preventing a recurrence necessitates complete abstinence to facilitate recovery. Many researchers feel that CHS is underrecognized and underdiagnosed.

Diagnosis of CVS/CHS is an interdisciplinary approach and provides a challenge to all disciplines involved 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 14, 15. A detailed history of the patient and a thorough clinical examination may justify corroborated suspicion 1, 2. Laboratory examination, abdominal ultrasound, oesophago-gastro-jejunoscopy and gastric emptying speed analysis should be performed in every suspected case. In a great number of patients, history of the patient, clinical examination, laboratory examination and abdominal ultrasound is sufficient for diagnosis of CVS or CHS. In some (atypical) cases, findings may indicate an organic cause which then requires extended examination including radiographic imaging, e.g. computed tomography or magnetic resonance imaging. Consultation of a psychiatric expert can be necessary to rule out psychogenic vomiting, eating disorders and psychiatric comorbidities.
