Gastro-oesophageal reflux disease (GORD) is a digestive condition that commonly occurs in one in five people. It can affect people of all ages, including children. It is most common in adults aged 40 and over and occurs more in men than in women. Acid reflux occurs when stomach acid leaks out of the stomach and into the gullet (oesophagus), which is a long tube that runs from the mouth to the stomach. Acid reflux is most commonly caused by weakening of the lower sphincter muscles of the gullet.

The common symptoms of GORD (acid reflux) include:

• Heartburn – a burning pain or discomfort below the breastbone, usually worse after meals,or when bending down, or when lying down
• An unpleasant taste in the mouth, caused by reflux of acid from the stomach
• Pain and difficulty in swallowing (dysphagia)

Most people respond well to treatment with medication and some people may require a long-term course of medication to control the symptoms of acid reflux.
