Overview of Nausea- Severe

Nausea is having the feeling or urge to vomit. In some cases, nausea can be debilitating and lead to vomiting, which means to forcefully throw-up the contents of the stomach out through the mouth. While nausea is most commonly caused by viral gastroenteritis (“stomach flu”), it can develop for a wide variety of reasons, including, but not limited to, medications, chemotherapy, food poisoning, morning sickness, general anesthesia, motion sickness, migraines, Crohn’s disease and other irritable bowel syndromes, and liver or pancreatic cancer.

Nausea and vomiting both play an important defensive role by rejecting the ingestion or digestion of potentially harmful substances. The sensitivity of the nausea and vomiting reflex, however, is very low and it can be easily activated, causing additional problems and impacting the quality of a patient’s life8. For example, nausea and vomiting can prevent the body from keeping down much-needed medications intended to treat serious conditions.

For cancer patients, nausea can develop after chemotherapy or radiation treatment, but it’s not uncommon for them to also experience anticipatory nausea. If a patient has previously gotten sick numerous times following treatment, for example, the smells, sights and sounds of the treatment room can trigger nausea even before treatment has begun.

Controlling nausea is important for allowing patients to continue their necessary medical treatment and to have a better quality of life. Not controlling nausea and vomiting can lead to chemical changes in the body, mental changes, loss of appetite, malnutrition, dehydration, a torn esophagus, broken bones and reopening of surgical wounds. In addition, nausea can cause longer hospital stays, difficulty handling everyday activities, lost work hours and depression.

Findings: Effects of Cannabis on Nausea-Severe

Cannabis has long been known to limit or prevent nausea and vomiting from a variety of causes7,12. The major cannabinoids within cannabis, tetrahydrocannabinol (THC) and cannabidiol (CBD), have both been shown effective at regulating nausea and vomiting because they interact with cannabinoid receptor 1 (CB1) of the endocannabinoid system. Activating the CB1 receptor suppresses vomiting6. Studies have shown that CBD’s effectiveness at producing anti-nausea effects may also be in part of its indirect activation of the sommatodendritic 5-HT(1A) autoreceptors in the brain stem10.

For patients suffering from nausea following cancer treatments, cannabis has shown it can provide relief. Studies have found that cannabinoids, including CBD contained in cannabis, are effective at treating the more difficult to control symptoms of nausea, as well as preventing anticipatory nausea in chemotherapy patients8. Another study found that THC was also effective at reducing conditioned rejection and chemotherapy-induced nausea2.
