Barrett’s oesophagus is a condition that can occur in response to acid damage in the oesophagus. The cells lining the oesophagus change their cell type, and this is a risk factor for developing oesophageal cancer.
Barrett’s oesophagus is more common in people who suffer from gastro-oesophageal reflux disease (acid reflux), but can occur in people who have no symptoms at all. The condition itself causes no symptoms.
Because of the increased risk of oesophageal cancer, people with Barrett’s oesophagus may be advised to have regular endoscopy procedures to monitor the oesophagus, and check for any early signs of oesophageal cancer.
