What Is Heartburn? Meaning on Antacid Labels
Heartburn · say it: HART-burnAlso written: acid indigestion, pyrosis, acid reflux symptoms
Short answer
Heartburn is a burning feeling in the chest or throat caused by stomach acid coming back up into the food pipe.
What it means
Heartburn is a burning discomfort behind the breastbone, sometimes rising to the throat, often after eating or when lying down. It happens when stomach acid flows back up into the esophagus (food pipe). Despite the name, it has nothing to do with the heart itself. Chest pain that spreads to the arm, jaw or back, or comes with breathlessness or sweating, needs urgent medical help because it can be a heart problem.
The word appears on over-the-counter antacid, H2 blocker and proton pump inhibitor labels, which are used to relieve or prevent it. These labels often say to ask a doctor if heartburn lasts more than a certain time, or if you have trouble swallowing, vomiting or weight loss, because frequent heartburn can be a sign of a condition that needs checking.
Heartburn is a symptom. GERD is the name for frequent, long-term reflux. Esophagitis is inflammation of the food pipe that reflux can cause.
