Heartburn, Gastroesophageal Reflux (GER) and Gastroesophageal Reflux Disease (GERD)

Gastroesophageal Reflux Disease (GERD) is a more serious form of Gastroesophageal Reflux (GER), which is very common. GER occurs when the lower esophageal sphincter (LES) opens spontaneously for different periods of time or does not close properly, and the contents of the stomach rise up into the esophagus. GER is also called acid reflux or acid regurgitation because digestive acids rise up with the food.

When reflux occurs, people can have indigestion where they can even taste food or fluid in the back of the mouth. Also, when the acid touches the lining of the esophagus it can cause heartburn, a burning sensation in the chest or throat. Frequent GER should be investigated by a gastroenterologist.
