A
Vomiting is reverse peristalsis. Instead of food moving down the GI tract, the peristalsis muscles move the contents of the stomach back through the esophagus and forcefully out the mouth. Forward peristalsis would cause food to continue through the gastrointestinal tract. Vomiting is usually involuntary and not connected with an eating disorder. Gastroesophageal reflux causes food from the stomach to back up into the esophagus, but is less intense than vomiting.
