Nausea and Vomiting

Nausea is the subjective feeling of a need to vomit. Vomiting (emesis) is the oral expulsion of upper gastrointestinal contents resulting from contractions of gut and thoracoabdominal wall musculature. Investigations depend upon the severity of the problem, suspected underlying aetiogy and urgency to treat. Therapy of vomiting is individualized depending on the underlying disease and severity. Hospitalization is considered for severe dehydration, especially if oral fluid replenishment is not possible.
