What is nausea?

Nausea is a very common symptom that is often described as a feeling of queasiness or wooziness, or a need to vomit. Nausea accompanies a wide variety of mild to serious infections, diseases, conditions, and injuries, and it occurs in all age groups and populations.

Symptoms of nausea can be short-term and disappear quickly, as in the case of indigestion. But symptoms can also be long-lasting or recur over a period of days, weeks, and months, such as nausea induced by migraine, cancer, pancreatitis, certain medications, or body trauma.
