Acid reflux is when stomach acid flows from the stomach upwards into the oesophagus, which is the tube connecting your mouth with your stomach. Acid reflux can cause irritation of the lining of the oesophagus. Gastro-oesophageal reflux disease (GORD or GERD) is a general term which can include symptoms of acid reflux, heartburn, indigestion and oesophagitis (inflammation of the lining of the oesophagus). 

Many people experience acid reflux from time to time. Most people can manage the symptoms with lifestyle changes and simple medications from their pharmacy. Some people suffering from GORD may need stronger medications or even surgery to treat their symptoms.

Anyone with GORD symptoms that are not settling, or that are getting worse over time, should seek medical advice, as investigations may be required to rule out more serious underlying conditions.
