Document Summary

Nausea and vomiting are the most common manifestations of gastrointestinal (gi) diseases. Nausea is a feeling of discomfort in the epigastrium with a conscious desire to vomit. Vomiting is the forceful ejection of partially digested food and secretions (emesis) from the upper gi tract. These simultaneous activities force the stomach contents up through the esophagus, into the pharynx, and out the mouth. Nausea and vomiting are found in a wide variety of gi disorders as well as in conditions that are unrelated to gi disease. Anorexia (lack of appetite) usually accompanies nausea and is brought on by unpleasant stimulation involving any of the five senses. When nausea and vomiting are prolonged, dehydration can rapidly occur. In addition to water, essential electrolytes (e. g. , potassium, sodium, chloride, hydrogen) are also lost. As vomiting persists, there may be severe electrolyte imbalances, loss of extracellular fluid volume, decreased plasma volume, and eventually circulatory failure.
