What is GERD?

Gastroesophageal reflux disease (GERD) occurs when the lower esophageal sphincter opens spontaneously, for varying periods of time, or does not close properly and stomach contents rise up into the esophagus. GERD is also called acid reflux because the digestive juices and food that rises up into the esophagus has acid mixed in with it.

When acid reflux occurs, food or fluid can often be tasted in the back of the mouth. When refluxed stomach acid touches the lining of the esophagus it may cause a burning sensation in the chest or throat called heartburn or acid indisgestion.

Occasional reflux is common and does not necessarily mean one has a serious problem. However, persistent reflux that occurs more than twice a week is considered GERD, and it can eventually lead to more serious health problems.
