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.
Heartburn is a painful burning sensation, experienced in the chest area due to the reflux of acid and other stomach contents in the oesophagus. This reflux, triggered usually by poor diet and lifestyle is caused by the relaxation or reduction in pressure of lower oesophageal sphincter. Heartburn is a common physiological condition, experienced occasionally by most adults but its ignorance can lead to a severe form known as gastro oesophageal reflux disease.
