Vomiting

Vomiting is defined as the forceful expulsion of gastric contents through the mouth and/or nose. Vomiting differs from gastroesophageal reflux (GER) and regurgitation in that the latter 2 conditions are characterized by effortless retrograde flow of duodenal or gastric fluids into the esophagus and oral cavity.” (Shields & Lightdale, 2018)
