About Cannabinoid (Marijuana) Hyperemesis Syndrome
The causes of CHS are still being studied, and researchers have not yet determined the exact reason this syndrome may occur. However, it’s believed that long-term, regular cannabis use may play a role in the development of CHS. Some of the active substances in cannabis, such as tetrahydrocannabinol (THC), the active substance responsible for causing a high from marijuana. THC may bind to receptors in the digestive tract and cause changes that could lead to CHS. It’s important to note that only a fraction of habitual cannabis users develop CHS.
As for the non-modifiable risk factors of CHS, there are currently no known factors that cannot be altered or modified. However, it’s worth mentioning that some individuals may be more susceptible to developing CHS due to genetic factors or other unknown predisposing factors.
On the other hand, modifiable risk factors (factors that can be influenced or changed) for CHS include:
- Long-term, regular cannabis use: The frequency and duration of cannabis use can increase the risk of developing CHS.
- THC potency: The higher the concentration of THC in cannabis products, the greater the potential risk for CHS.
- Route of administration: Frequent use of high-potency cannabis products through inhalation or ingestion may increase the risk.
It's important to remember that these risk factors are based on current understanding and research findings. If you suspect you have CHS or have concerns about your cannabis use, it is advisable to consult with a healthcare professional who can provide personalized guidance and support.
The most common early symptoms of CHS include:
- Abdominal discomfort
- Fear of vomiting
- Early morning nausea
As CHS progresses or becomes more severe, additional symptoms may occur, such as:
- Overwhelming nausea and vomiting
- Dry heaving
- Decreased food intake
- Food aversions
- Anxiety
- White, watery secretions in vomit from lack of solid food
- Abdominal pain
- Weight loss
- Dehydration
Bathing in hot water can temporarily relieve CHS symptoms in some people. It's important to note that these symptoms typically resolve within days or months after stopping cannabis use. However, if cannabis use is resumed, the symptoms of CHS may reoccur. If you suspect you have CHS, it's crucial to consult with your healthcare provider for an accurate diagnosis and appropriate management strategies.
To diagnose CHS, healthcare professionals typically perform the following examinations, tests, and procedures:
- Symptom assessment: Healthcare professionals will study your symptoms, including significant nausea, vomiting, and abdominal pain, especially with chronic cannabis use.
- Medical history: They will ask about your cannabis use patterns and frequency of symptoms.
- Physical examination: Healthcare professionals will examine your abdomen for any signs of tenderness or abnormalities.
- Laboratory tests: Blood and urine tests may be ordered to rule out other potential causes of your symptoms and assess your overall health.
- Imaging tests: Depending on the severity of your symptoms, healthcare professionals may order a CT scan or X-ray of your abdomen to rule out other conditions.
- Endoscopy: In some cases, an upper endoscopy may be performed to evaluate the upper digestive tract for any abnormalities.
To determine the stage or severity of CHS, additional examinations, tests, and procedures may include:
- Abdominal ultrasound: This imaging test can provide detailed images of the abdominal organs to assess for any abnormalities.
- Gastric emptying speed analysis: This test measures how quickly food moves through your stomach to evaluate gastrointestinal motility.
While these examinations and tests can help diagnose and assess CHS, it's important to consult with a healthcare professional for personalized evaluation and guidance. .
The goals of treatment for CHS are to alleviate symptoms, prevent complications, and promote long-term recovery. Here are the recommended treatments and how they work to achieve these goals:
- Stop cannabis use: The primary and most effective treatment for CHS is to stop using cannabis completely. This helps in eliminating the symptoms and preventing further episodes.
- Symptom management: Various medications can be used to manage the symptoms of CHS, including anti-nausea medications (antiemetics) and pain relievers. These medications help in reducing nausea, vomiting, and abdominal pain.
- Behavioral changes: Making certain lifestyle modifications can also be beneficial in managing CHS. These may include avoiding hot showers or baths, as they can provide temporary relief but may worsen symptoms in the long run.
- Supportive care: Providing supportive care to patients with CHS is important. This involves ensuring adequate hydration and electrolyte balance through intravenous fluids if necessary.
It's important to note that while these treatments can help manage symptoms, the only way to fully resolve CHS is by discontinuing cannabis use completely. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your healthcare professional or read the information provided with your medication for additional side effect information.
