Along with the discovery of the CB1 and CB2 receptors has been the identification of endogenous arachidonic acid derivatives that bind to these receptors (Figure 1). These compounds are referred to as endogenous cannabinoids, or endocannabinoids. The best characterized endocannabinoids are anandamide and 2-arachidonylglycerol (2-AG) [9]. The endocannabinoids are present in both the central nervous system [8] and enteric nervous system [15]. Anandamide and 2-AG are released locally on demand by neurons, are present in small quantities, and undergo rapid inactivation [8].
What do experts know about CHS?
In two case reports, doctors used lorazepam (Ativan) to manage CHS-related nausea and vomiting. However, many experts consider these treatments to be ineffective for managing nausea and vomiting in people with CHS. As people with CHS often only consult their doctors during the hyperemesis stage, there is a lack of knowledge regarding the treatment of people during the prodromal stage. Doctors have also noticed that people in the hyperemesis stage take frequent showers and baths, which seem to relieve nausea.
Cannabinoid Hyperemesis Syndrome: Diagnosis, Pathophysiology, and Treatment—a Systematic Review
The cannabis plant contains over four hundred different chemicals, with sixty possessing cannabinoid structures [76]. The pro-emetic effects of two of these cannabinoids, CBD and CBG, have been discussed cannabinoid hyperemesis syndrome in this review and could conceivably play a role in the development of CHS. Additional pharmacological research is needed regarding the pro-emetic effects of additional cannabinoids and their metabolites.
Drugs & Supplements
The signature symptoms of Cannabinoid Hyperemesis Syndrome seem to be temporarily relieved by hot baths and showers, suggesting that temperature may play a role in regulation. Overnight, the nursing staff reported that the patient took multiple, prolonged hot showers. Upon further questioning, he reported the hot showers significantly helped the nausea and abdominal pain. He had learned this behavior after experiencing previous episodes of self-limited nausea, vomiting, and abdominal pain. First, doctors treating people with CHS advise them to stop using marijuana.
Complications
CHS usually starts after years of using marijuana many times a week. Initial symptoms are feeling sick to the stomach, belly pain and the feeling like you may throw up. After about years of chronic marijuana use, patients begin to have a strong feeling of sickness, throwing up, and belly pain. This is normally when people go see a doctor to find out what is causing these problems.
What are the symptoms of cannabinoid hyperemesis syndrome?
Previous evaluations included additional unremarkable CT imaging of the abdomen and pelvis. The patient also had received 2 esophagogastroduodenoscopies (EGDs), one 2 years prior and the other 5 years prior. On every check during the previous 8 years, the patient’s UDS was positive for THC. Researchers need to study CHS in more detail to make it easier for doctors to recognize and treat the condition.

Two case series and numerous individual case reports have been published on Cannabinoid Hyperemesis Syndrome (CHS) (Table 1). Patients present with recurrent episodes of nausea, vomiting, and dehydration with frequent visits to the emergency department. Patients are typically young adults with a long history of cannabis use. In nearly all cases there is a delay of several years in the onset of symptoms preceded by chronic marijuana abuse [6].
Clinical Presentation, work up and differential diagnosis of Cannabinoid Hyperemesis Syndrome
- Researchers have identified two receptors called CB1 and CB2 to which marijuana molecules attach.
- Additional treatments are needed and efforts to discontinue cannabis abuse are paramount.
- If you have symptoms, your doctor will do a physical exam and ask for your detailed medical history.
- Keep in mind none of these treatments will be effective if you continue using cannabis products.
Cannabinoid hyperemesis syndrome (CHS) is a condition in which a patient experiences cyclical nausea, vomiting, and abdominal pain after using cannabis. The almost pathognomic aspect of a patient’s https://ecosoberhouse.com/ presenting history is that their symptoms are relieved by hot baths or shower. This activity introduces the pathophysiology, clinical manifestation, and management of cannabis hyperemesis.
- She asked to be identified only by her first name for fear of how future employers may view her history of marijuana use.
- In one 2018 study, a group of researchers surveyed 2,127 U.S. adults between the ages of 18 and 49 at an emergency department in New York.
- The word “cannabinoid” refers to compounds uniquely found in cannabis, and “hyperemesis” means severe vomiting.
- Research suggests that CB1 receptors regulate the effects of marijuana on the gastrointestinal tract.
