What Are the Most Common Signs of Heartburn?
Heartburn, which is the sensation caused by acid reflux, usually has strong symptoms. The most common of the signs of heartburn is a burning feeling in the chest due to stomach acid coming back up, or refluxing. It’s because of this feeling that this most common acid reflux effect became commonly known as “heartburn.” The condition has nothing to do with the heart, however, as the burning sensation is excess stomach acid coming up through the esophagus, which is the tube in which consumed food and beverages travel down to be digested. Since the esophagus is located just behind the breastbone, which is fairly close to the heart in the chest, “heartburn” caught on as the lay term to express the pain caused by acid reflux related disorders.
