Nausea is the sensation felt immediately before vomiting.
Vomiting is a partially voluntary act of forceful expelling of stomach contents up to and out of the mouth that may or may not be preceded by nausea.
Retching or repetitive active contraction of the abdominal muscles occurs between nausea and vomiting.
Management includes correction of clinically relevant metabolic complications, pharmacological therapy and treatment of underlying cause.
