Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis Recurrent vomiting disorders typically include cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis syndrome (CHS). Recognizing their differences is essential for proper diagnosis and treatment.
CVS is an uncommon but debilitating disorder marked by repeated episodes of intense vomiting and abdominal pain. In contrast, CHS is a newer condition associated with heavy cannabis consumption, leading to severe nausea and vomiting. Although their symptoms overlap, they differ in causes and triggers. Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
Understanding Cyclic Vomiting Syndrome (CVS)
Cyclic Vomiting Syndrome (CVS) is a challenging disorder that affects people of all ages. It involves repeated episodes of intense vomiting, often with abdominal pain and nausea, lasting hours or days and significantly impairing daily life.
Signs of CVS: Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
- Frequent vomiting episodes
- Stomach pain and discomfort
- Feeling sick
- Migraine pain
- Light and noise sensitivity
It’s important to remember that symptom severity and frequency differ among individuals; some may have episodes monthly, while others experience them more often.
Causes of Cyclic Vomiting:
Recognizing the factors that can trigger a CVS episode is essential for effective management. Typical triggers include:
- Mental strain
- Health infections or diseases
- Lack of sleep
- Overeating or prolonged fasting
- Particular foods or odors
Identifying and avoiding triggers can help individuals with CVS reduce the frequency of vomiting episodes.
CVS Treatment Alternatives:
Although CVS has no cure, various treatments can help control symptoms and enhance quality of life, including:
- Medications for nausea relief
- Analgesics
- Medications for migraines
- Identifying and steering clear of triggers
- Methods for managing stress
Individuals with CVS should collaborate closely with their healthcare providers to create a tailored treatment plan that effectively targets their unique symptoms and needs. Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
Understanding Cannabinoid Hyperemesis Syndrome (CHS)
Cannabinoid hyperemesis syndrome (CHS) is a growing condition associated with cannabis use. It causes intense nausea, ongoing vomiting, and abdominal pain, severely affecting daily functioning.
The precise cause of CHS remains unclear, but it is thought to stem from prolonged marijuana use. High concentrations of cannabinoids like THC may trigger symptoms. However, not all cannabis users develop CHS, and the condition is relatively uncommon.
Diagnosing CHS is often difficult due to symptom overlap with other gastrointestinal conditions. Healthcare providers usually base their diagnosis on medical history,

physical exams, and lab tests. Anyone showing signs of CHS should consult a doctor for proper evaluation.
Typical Signs of Cannabinoid Hyperemesis:
- Intense nausea
- Frequent vomiting episodes
- Stomach pain or discomfort
- Fat reduction
- Dehydration
Hot baths or showers can temporarily ease CHS symptoms, but this relief is usually short-lived and symptoms tend to return.
If you or someone you know shows signs of CHS, seek medical advice promptly. Early diagnosis and proper treatment can reduce symptoms and enhance quality of life.
Triggers: Key Factors That Spark Episodes
To effectively manage cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis (CHS), it’s essential to recognize and avoid specific triggers that provoke vomiting episodes. Doing so can help decrease both their frequency and intensity.
Causes of Cyclic Vomiting Syndrome (CVS)
Cyclic vomiting syndrome may be triggered by several factors, such as:
- Elevated emotional stress can trigger vomiting episodes in CVS sufferers.
- Dietary triggers—specific foods or additives like chocolate, caffeine, and MSG—can induce vomiting episodes.
- Physical fatigue and sleep deprivation can trigger CVS episodes.
- Illnesses or infections, whether viral or bacterial, can trigger CVS episodes.
Keeping a journal is essential for individuals with CVS to track triggers and adjust their lifestyle, aiding in better management and fewer episodes.
Triggers of Cannabinoid Hyperemesis Syndrome (CHS)
Cannabinoid hyperemesis syndrome (CHS) is mainly linked to prolonged marijuana use. Although its exact causes remain unclear, it is thought that active cannabis compounds may induce the following symptoms: Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
- Cannabis use—smoking or ingesting—may trigger intense nausea and vomiting in those with CHS.
- Hot showers or baths may temporarily relieve CHS symptoms for some, but can also trigger future episodes.
- Products with elevated THC levels may raise the likelihood of experiencing CHS symptoms due to its psychoactive effects.
Not all marijuana users develop CHS, and it typically affects those who have used cannabis for many years. If you experience repeated vomiting after using marijuana, it’s important to see a healthcare professional for proper diagnosis and treatment.
| Trigger | Cyclic Vomiting Syndrome (CVS) | Cannabinoid Hyperemesis (CHS) |
|---|---|---|
| Emotional stress | Can trigger episodes | Not a typical trigger |
| Dietary triggers | Can provoke episodes (e.g., chocolate, caffeine, MSG) | —— |
| Physical exhaustion | Can contribute to episodes | —— |
| Illness or infections | Can act as triggers | —— |
| Cannabis use | Not applicable | Can provoke episodes |
| Hot showers or baths | Not applicable | Can alleviate symptoms but may also trigger future episodes |
| High THC concentration | Not applicable | Can increase risk of CHS symptoms |
Understanding Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
To accurately diagnose cyclic vomiting syndrome (CVS) and cannabinoid hyperemesis (CHS), healthcare providers perform a comprehensive evaluation, including medical history, physical exam, and specific criteria to distinguish between the conditions.
For CVS diagnosis, clinicians focus on repeated episodes of intense vomiting and abdominal pain lasting hours or days, often occurring at regular intervals. These episodes are usually accompanied by nausea, pallor, and fatigue. A thorough medical history is essential to recognize these patterns and exclude other possible causes.
Diagnosing CHS involves a thorough review of the patient’s medical history and symptoms. Typical signs include intense nausea, vomiting, and abdominal pain, usually linked to cannabis use. Healthcare providers will examine the patient’s marijuana use and its timing relative to symptom onset.
To distinguish CVS from CHS, clinicians use specific criteria. CVS is diagnosed when there are at least three episodes of severe vomiting within a year, each lasting under a week, with symptoms between episodes, per Rome IV guidelines. CHS diagnosis involves chronic cannabis use, cyclic vomiting episodes, and symptom relief upon stopping cannabis. Differences Between Cyclic Vomiting Syndrome and Cannabinoid Hyperemesis
Understanding CVS vs. CHS: A Diagnostic Overview
| Criteria | Cyclic Vomiting Syndrome (CVS) | Cannabinoid Hyperemesis (CHS) |
|---|---|---|
| Recurrent episodes | ✓ | ✓ |
| Duration of episodes | Several hours to days | Variable, typically resolved after cannabis cessation |
| Associated symptoms | Nausea, pallor, exhaustion | Severe nausea, abdominal discomfort |
| Triggers | Various, including stress, infections, certain foods | Cannabis use |
By thoroughly assessing symptoms and medical history with these criteria, healthcare providers can accurately diagnose CVS or CHS and determine suitable treatment plans. Prompt medical consultation is essential for proper diagnosis and effective symptom management.
Treatment Strategies for Cyclic Vomiting Syndrome
Cyclic Vomiting Syndrome (CVS) can severely impact daily life, but multiple treatments exist to control symptoms and reduce future episodes. The appropriate approach varies based on the individual’s condition, symptoms, and health. Below, we outline both medication-based and alternative options for managing CVS.
