Heartburn is a common symptom of acid reflux, a condition where some of the stomach contents travel back up into the esophagus, or food pipe. It creates a burning pain in the lower chest.

Persistent acid reflux that happens more than twice per week is what experts call gastroesophageal reflux disease (GERD).

A person will feel heartburn when stomach acid flows back up into the esophagus, the pipe that carries food from the mouth to the stomach. Heartburn is a symptom of GERD.

The American College of Gastroenterology estimate that more than 15 million people in the United States experience heartburn symptoms every day.
