Evaluation of nausea and vomiting, adults

Last reviewed: June 2018

Summary

Nausea and vomiting are extremely common symptoms and may be caused by a vast array of medical conditions. [1] [2] [3] The presentation can be acute or chronic and ranges from a mildly annoying symptom to a condition that impairs quality of life or is a marker of a life-threatening disease.

There are 2 general mechanisms of nausea and vomiting:

Neurologic

Stimulation of the area postrema, which "senses" noxious chemical agents (e.g., poisons, chemotherapy agents, digoxin) and subsequently stimulates the vagal nuclei, which evokes nausea and coordinates the emesis reflex.
CNS diseases such as infections or brain tumors stimulate CNS structures and elicit nausea and vomiting, ultimately through vagal pathways.

Peripheral

Diseases and disorders that originate in peripheral organ systems, such as the GI tract, stimulate vagal or spinal afferent nerves that connect with the vagal sensory (tractus solitarius) and vagal efferent motor nuclei. Ultimately, cortical centers where nausea is perceived and the efferent pathways that mediate vomiting are stimulated.
Tumors, infections, and drugs in the periphery may cause local dysfunction in a variety of organ systems that is sensed as nausea, and severe nausea eventually evokes vomiting.
