What is nausea and vomiting?
Nausea is feeling queasy or sick to your stomach, like you’re going to throw up. Vomiting is emptying your stomach by throwing up. Nausea and/or vomiting are frequent side effects of chemotherapy and radiation therapy. Chemotherapy-induced nausea and vomiting can be acute (within the first 24 hours), delayed (vomiting that occurs after 24 hours) and/or anticipatory. Anticipatory vomiting is a learned response, which means it happens in response to a stimulus, chemotherapy. With this type of nausea and vomiting, the symptoms usually occur after initial exposure to chemotherapy drugs and before subsequent treatments.
