What is Esophageal mucosal changes?

Esophageal mucosal changes refer to alterations in the lining of the esophagus, which can result from various conditions such as gastroesophageal reflux disease (GERD), infections, or chronic inflammation. These changes may include hyperemia, erosion, or metaplasia, such as Barrett's esophagus, where the normal squamous epithelium is replaced by columnar cells. These alterations can lead to symptoms like heartburn, difficulty swallowing, and an increased risk of esophageal cancer. Diagnosis often involves endoscopy and biopsy to assess the nature and extent of the changes.
