K22.7: Barrett oesophagus

Barrett's oesophagus is a condition where the tissue lining the lower part of the oesophagus, the tube through which food and drink reach the stomach, changes. The normal cells in this part of the oesophagus are replaced by abnormal cells. This alteration typically happens over time and is a result of chronic, prolonged exposure to stomach acid, which occurs when the muscle at the lower end of the oesophagus doesn't function properly. This allows acid to flow back into the oesophagus, a condition known as gastroesophageal reflux disease (GERD). Symptoms of Barrett's oesophagus mimic those of GERD, such as heartburn and acid reflux. However, many people may not have any noticeable symptoms, making it important to monitor for any unusual or persistent problems. Over time, Barrett's oesophagus can lead to oesophageal adenocarcinoma, a rare type of oesophageal cancer.
