One thought on “Why do cancer patients experience nausea and vomiting?

    As a result of widespread use of antiemetics, nausea and/or vomiting is not as severe and does not occur as frequently as in the past. Many new and improved medicines for controlling nausea and vomiting, called antiemetics, have been developed over the last several years. The best way to treat nausea and vomiting is to prevent it from occurring in the first place. These drugs block the signal in the brain that causes nausea and vomiting. A specific location in the brain controls emesis (vomiting), called the vomiting center. Emesis occurs when the vomiting center receives a signal from the brain, the gastrointestinal tract, the heart and/or the inner ear, which detects motion. Chemotherapy causes the release of a substance called serotonin (5-HT), and of other chemicals in the small intestine, which through a series of signals stimulate the vomiting center in your brain to induce emesis.
