How is cannabis hyperemesis syndrome diagnosed?

Your healthcare provider diagnoses CHS based on your symptoms. If you are vomiting frequently, tell your provider about all substance use, including cannabis. Your provider may ask you:

• How often you use cannabis.
• How long you have used cannabis.
• When you vomit or feel nauseated.
• If other factors, such as certain foods, lead to vomiting.
• Whether you have lost weight for no known reason.
• If you take hot baths or showers to try to relieve symptoms.

You may also have blood tests, a CT scan or MRI to rule out other causes of nausea and vomiting. You may also take a pregnancy test if pregnancy is a possibility.
