What Are the Causes of Barrett’s Esophagus?
Researchers are yet to discover the exact cause of Barrett’s esophagus. However, studies have linked the condition to gastroesophageal reflux [1] (GERD), a disease that occurs when the muscles at the inferior portion of the esophagus do not work well. The muscles will lose their ability to prevent food and acid from going up into the esophagus.
Studies show that the cells in your esophagus become abnormal if they are exposed to stomach acid for a long time. It is important to note that Barrett’s esophagus can occur without GERF. However, people with GERD are more likely to have Barrett’s esophagus.
Over 5% of people with GERD develop Barrett’s esophagus. It is more common in men than in women and is mostly diagnosed after 55 years. After a while, the cells lining your esophagus will grow into precancerous cells. These cells may then change into cancerous cells. However, it is important to note that people with Barrett’s esophagus don’t always develop cancer. Studies show that only about 0.5% of people with the condition develop cancer.
