Barrett’s esophagus, also known as Barrett’s esophagus, is a precancerous condition. However, it can usually be cured with aggressive treatment. Otherwise, it is more likely to develop into adenocarcinoma, which is more serious. Barrett’s esophagus refers to the squamous epithelial cells in the lower part of the esophagus being covered by columnar epithelium, mainly due to reflux esophagitis. Patients usually do not have obvious symptoms, and some patients may also experience discomfort such as acid reflux and heartburn and difficulty in swallowing. Barrett’s esophagus can usually be cured and patient’s symptoms relieved with active treatment, such as medication (acid-suppressing drugs such as omeprazole, mucosal-protecting drugs such as bismuth potassium citrate, and pro-dynamic drugs such as domperidone, etc.), and surgery, which is usually not serious. However, if the patient is not treated in time, the disease further develops and there is a tendency of adenocarcinoma, then there is a possibility of cancer, which is more serious. Patients with Barrett’s esophagus are advised to seek medical treatment in time and actively receive treatment. Medications should be taken in strict accordance with the doctor’s prescription, and should not be used on their own, so as to avoid delaying or even aggravating the condition.
