Why do I get sick?

Nausea is controlled by a part of the nervous system that controls certain body functions that we often take for granted, like breathing. A special area of the brain called the vomiting center manages vomiting.

When a person receives chemotherapy, radiation therapy or following some surgical procedures, the body releases a chemical that causes the vomiting center to cause nausea and vomiting.
