Q

What is the definition of gastro-oesophageal reflux?

A

Some degree of reflux is physiological. Reflux is a normal process, and is often asymptomatic. Pathological reflux is when abnormal exposure of the oesophagus to gastric acid leads to symptoms or mucosal injury.

Q

What can cause symptoms of GORD?
