The most common problem with the esophagus is gastroesophageal reflux disease (GERD).
Gastroesophageal reflux disease (GERD) occurs when the lower esophageal sphincter, which acts as a valve between the esophagus and stomach, becomes weak or relaxes, causing stomach contents to rise up. The most common problem with the esophagus is GERD, which can cause damage to the esophagus over time.
Anyone, including infants and children, can have GERD. If not treated, it can lead to more serious health problems, including the risk of developing cancer of the esophagus. If you have had symptoms of GERD and have been using antacids or other over-the-counter reflux medications for more than two weeks, see your healthcare provider.
