What Is Chemotherapy-Induced Nausea and Vomiting (CINV)?
Chemo-related nausea and vomiting are side effects of chemotherapy medicines, or chemo, for short. Side effects happen when chemo damages healthy cells. You may also hear or see the term chemotherapy-induced nausea and vomiting, or CINV.
- Nausea is the feeling you have when you need to vomit, or throw up
- Vomiting is the act of throwing up what is in your stomach
Some people may or may not have these side effects. Some people may have nausea or vomiting, or both. For some people, nausea can be worse than vomiting, because once it starts it can be hard to stop. Certain types of chemo medicine are more likely than others to cause nausea and vomiting. The goal is prevention.
The good news is that chemotherapy-induced nausea and vomiting (CINV) can be stopped before it starts.
