What Is Acid Reflux?
Acid reflux disease, also known as gastro-esophageal reflux
disease, or GERD, occurs due to the coexistence of two medical conditions. The
first acid reflux disease contributing condition is a retrograde flow of stomach
contents into the esophagus. However, the reflux itself does not necessarily
lead to gastro-esophageal reflux disease symptoms or histologic changes, and can
occur among healthy individuals as well. In this case, the process is referred
to as "physiologic gastroesophageal reflux".
