Is heartburn the same as acid reflux?

Heartburn is simply the common term for acid reflux. It is the symptom described when acid is regurgitated into the esophagus from the stomach. It is commonly felt as a burning in the chest behind the sternum (breastbone) or just below the sternum. Frequent heartburn or acid reflux can be a symptom of gastroesophageal reflux disease, also known as GERD, and should be treated by medical personnel.
