Barrett's oesophagus is a pre-cancerous condition of the lining of the oesophagus, the muscular tube that carries foods, liquids and saliva from the mouth to the stomach.
Barrett's oesophagus is caused by the long-term exposure of the oesophagus to acid reflux, a medical condition also known as GORD ( gastro oesophageal reflux disease).
When stomach acids back up into the oesophagus, the lining of the oesophagus can become injured. In some cases, the oesophageal lining may develop into a different kind of tissue which resembles the lining of the intestine. This change is Barrett's oesophagus.
Barrett's oesophagus prevalence is estimated to affect between 2 and 7 million adults over 40 years of age in the United States.
Patients with Barrett's Oesophagus are 30-125 times more likely to develop adenocarcinoma (oesophageal cancer) than the general population.
The incidence of oesophageal adenocarcinoma has risen approximately six-fold in the U.S. It is rising faster than breast cancer, prostate cancer, or melanoma.
Stomach acids back up into the oesophagus from acid reflux or GORD, causing injury to the oesophageal lining.
