For the novel, see Heartburn (novel) . Heartburn, also known as pyrosis, cardialgia, or acid indigestion, is a burning sensation in the chest, just behind the breastbone or in the epigastrium, the upper central abdomen. The pain often rises in the chest and may radiate to the neck, throat, or angle of the jaw.
Despite its name, heartburn has nothing to do with the heart (although some of the symptoms are similar to a heart attack). Heartburn is an irritation of the oesophagus caused by stomach contents, including stomach acid, that refluxes (comes up) from the stomach. Heartburn is also a symptom of more serious gastro-oesophageal reflux disease, or GORD. When swallowing, food passes down the throat and through the oesophagus to the stomach.
