Nausea vs. Vomiting — What's the Difference?

Nausea is a diffuse sensation of unease and discomfort, often perceived as an urge to vomit. While not painful, it can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, upper abdomen, or back of the throat.Over 30 definitions of nausea were proposed in a 2011 book on the topic.Nausea is a non-specific symptom, which means that it has many possible causes.

Vomiting (also known as puking, throwing up, barfing, emesis, among other names) is the involuntary, forceful expulsion of the contents of one's stomach through the mouth and sometimes the nose.Vomiting can be caused by many conditions; it may be present as a specific response to ailments like gastritis or poisoning, or as a non-specific sequela ranging from brain tumors and elevated intracranial pressure to overexposure to ionizing radiation.
