What is regurgitation?

Regurgitation means backwards flow of a fluid. In the case of the GI tract, regurgitation is the forceful expulsion of stomach contents backwards through the esophagus and out the mouth. Regurgitation is an important body defense against noxious substances, but can be complicated by aspiration of stomach contents into the lungs, causing inflammation of the lungs. Repeated regurgitation is damaging to the tooth enamel, and can lead to disturbances of fluid, electrolyte and acid-base status.

Regurgitation is when food in the stomach comes back up in the esophagus.

The definition of regurgitation is simply fluid or material moving backwards; in the body, there are several examples of this. In the heart, regurgitation (known as "aortic regurgitation" or "mitral regurgitation") means that a defect in the heart valves allows some blood to flow in reverse from the normal flow. In the intestines and gastrointestinal tract, regurgitation means that undigested food and fluid from the stomach flows retrograde from the stomach back into the esophagus and even into the mouth.

Regurgitation refers to food or liquid that is coming up through the chest and expelled from the mouth.
