There is no identified sole cause of Gastro Oesophageal Reflux Disease. Gastro Oesophageal Reflux Disease usually occurs when the muscular valve between the stomach and the oesophagus, known as the lower oesophageal sphincter, is weak or faulty. This therefore allows the stomach acid to flow back into the oesophagus.
There are various risk factors that contribute to the onset of Gastro Oesophageal Reflux Disease, and these include:
- Certain diseases (Zollinger-Ellison Syndrome, Scleroderma)
- Increased production of gastrin, a hormone that regulates the release of stomach acid
- Use of certain medications
