Nausea refers to the sensation of uneasiness of the stomach or abdominal pains that often comes before vomiting.
Vomiting is the forcible voluntary or involuntary emptying (“throwing up”) of stomach contents through the mouth,
accompanied by abdominal pains. Abdominal pains, when recurring, may be a symptom of a further gastrointestinal issue.
Some triggers that result in vomiting may originate from the gastrointestinal tract.
