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.

Nausea occurs with other symptoms affecting the digestive system as well as other body systems.

Nausea associated with head injury, bloody stools, or vomiting of blood can be a symptom of a serious, potentially life-threatening condition and should be immediately evaluated in an emergency setting.
