It can be caused by changes in the middle ear, the intestinal tract, or the brain. A signal is sent to a section of the brain that controls vomiting. This causes the body to tighten muscles around the stomach. Anything in the stomach is then forcefully brought back up and expelled through the mouth.

Usually, nausea and vomiting lasts only a short period of time. Long periods of vomiting, or repeated episodes, can lead to dehydration. To avoid this, replace fluids lost through vomiting. All rights reserved. Information in this document is subject to change without notice.
