Acid Reflux

ALSW specialises in the endoscopic diagnosis and the surgical treatment of gastro-oesophageal reflux.

Gastro-Oesophageal Reflux

Gastro-Oesophageal reflux disease or as widely known, acid reflux is caused by return of acidic stomach juices, food and/or fluids, back up into the oesophagus due to a lax valve with or without hiatus hernia.


Heartburn, a burning sensation in the chest, is the most common symptom of gastro-oesophageal reflux and is often described as a harsh, burning sensation behind the breastbone, often accompanied by a sour taste and a sensation of food coming back into the mouth. It often gets worse when the person eats, bends over or lies down.

Gastro-Oesophageal Reflux Disease (GORD)

Anyone experiencing heartburn twice a week or more may have gastro-oesophageal reflux disease or GORD and should consult a specialist. Almost everyone experiences reflux and heartburn at one time or another, often after large meal. However, prolonged and frequent acid in the lower oesophagus can cause injury such as inflammation, ulceration, scar formation, and stricture and, after a long period of time, even cancer. Some people have severe symptoms with no tissue damage, while others may have few symptoms and much tissue damage.
