Gastro-oesophageal reflux disease (GORD) is defined as symptoms or mucosal damage produced by abnormal reflux of gastric content into the oesophagus (1)
There is a poor correlation between pathological and symptomatic severity of GORD. In other words, the relationship between reflux symptoms, endoscopic findings, and exposure of the oesophagus to acid is not straightforward (2)
Pressure and acid manometry studies show that gastro- oesophageal reflux occurs in normal situations, such as belching. It is quite difficult in some situations to decide when it is abnormal.
This condition may be investigated by endoscopy, barium swallow or by 24 hour pH monitoring.
It may cause reflux oesophagitis; thus, the oesophagitis occurs with the same aetiological factors as reflux, but occurs when the problem is severe or chronic.
