Understanding GORD

What Causes GORD?

Gastroesophageal Reflux Disease (GORD), also known as GERD, is a chronic, often progressive condition resulting from a weak Lower Oesophageal Sphincter (LOS). When left untreated, serious complications can result, including: oesophagitis, stricture, Barrett’s oesophagus, and oesophageal cancer.

The LOS is a ring of muscle at the junction of the oesophagus and stomach that functions as the body’s natural barrier to reflux. The LOS acts like a valve, allowing food and liquid to pass through to the stomach. Normally, the LOS closes immediately after swallowing, preventing reflux (Fig. 1). However, in people with GORD, the LOS is weak, allowing acid and bile to reflux from the stomach into the oesophagus (Fig. 2).
