Symptoms & Signs

Nausea is the sensation that there is a need to vomit. Nausea can be acute and short-lived, or it can be prolonged. When prolonged, it is a debilitating symptom. Nausea (and vomiting) can be psychological or physical in origin. It can originate from problems in the brain or organs of the upper gastrointestinal tract (esophagus, stomach, small intestine, liver, pancreas, and gallbladder). It also may be caused by pain, motion, medications and diseases of many nongastrointestinal organs of the body. Therefore, the diagnosis of the cause of prolonged nausea may not be easy. All stimuli that cause nausea work via the vomiting center in the brain which gives rise to the sensation of nausea and coordinates the physical act of vomiting.

Nausea symptoms are frequently difficult for people to describe. Nausea symptoms are not painful but very uncomfortable feelings that are felt in the chest, upper abdomen, or back of the throat. Nausea can also be associated with headache, dizziness, lightheadedness, diarrhea, abdominal pain, and a general feeling of being sick to one's stomach.
