Acid Reflux, Heartburn, & GERD

Technically, heartburn is the symptom you feel when acid splashes up and out of the stomach. "Heartburn" is sometimes used interchangeably with "acid reflux."

Acid reflux is when stomach acid splashes up from the stomach into the esophagus. Find out more about acid reflux disease, including symptoms, causes, diagnosis, treatments, and helpful diet and lifestyle tips.

GERD (gastroesophageal reflux disease) is severe or chronic acid reflux that can lead to complications, such as cancer.

When constant heartburn turns into GERD, do you know how to spot the difference?

Infants and children can experience that burning sensation in the chest. According to some estimates, about 2% of children ages 3 to 9, and 5% of children ages 10 to 17, have heartburn.

Laryngopharyngeal reflux (LPR) is similar to another condition -- GERD -- that results from the contents of the stomach backing up (reflux).

Triggers
