Medical Definition of Gastroesophageal reflux
1. The return of stomach contents back up into the oesophagus This frequently causes heartburn because of irritation of the oesophagus by stomach acid. Gastroesophageal reflux disease (GERD) can lead to scarring and stricture of the oesophagus, requiring stretching (dilating) of the oesophagus. 10% of patients with GERD develop Barrett's oesophagus which increases the risk of cancer of the oesophagus. 80% of patients with GERD also have a hiatal hernia.
