What Is GERD, Acid Reflux and Heartburn?
Gastroesophageal reflux disease (GERD), acid reflux and heartburn all occur when digestive juices rise up the digestive tract into the esophagus with food. This acid causes a burning sensation in the back of the throat and chest, which is where the name “heartburn” comes from.
GERD is generally considered more serious than acid reflux or heartburn, and requires a diagnosis from a medical professional, such as a gastroenterologist. While everyone may experience heartburn or acid reflux from time to time, GERD may be suspected if you experience reflux more than twice a week.
