Heartburn, conceptual image. Computer artwork representing a person suffering from heartburn. Heartburn is a burning pain caused by stomach acids escaping (refluxing) into the oesophagus and burning its lining. This is due to the stomach's cardiac sphincter, a ring of muscle that separates the stomach from the oesophagus, failing to close properly.
