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 condition that affects around 20% of the population every week. The symptoms of heartburn are a tight, painful feeling through your chest. Heartburn is caused by acid reflux, which happens when stomach acid is released into the esophagus. The stomach acid eats away at the lining of the esophagus and can cause lasting damage. If you experience frequent heartburn, you may have a condition called acid reflux disease, or gastroesophageal reflux disease (GERD).
