Heartburn
This symptom may be caused by a stretching of the esophagus (usually the lower part) either by swallowing too much food or drink in a single swallow or by the regurgitation of stomach contents into the lower esophagus. Heartburn does not indicate excess acidity in the stomach, for it may occur in persons who lack acid in their gastric juice. It occurs commonly in connection with dyspepsia.
