GERD, or gastroesophageal reflux disease, occurs when your stomach acid travels up into your esophagus, the tube connecting your mouth to your stomach. This causes heartburn, the sensation that comes from the flow of stomach acid into your esophagus and back out again, typically brought on by eating or drinking.

Heartburn may also be caused by a variety of other factors, including certain medications and lifestyle choices, but here are some things you can do to help prevent or manage GERD or heartburn symptoms so they don’t interfere with your daily life.
