Esophageal disorders refer to a range of conditions affecting the esophagus, the tube that carries food from the mouth to the stomach. Common disorders include gastroesophageal reflux disease (GERD), where stomach acid frequently flows back into the esophagus, causing heartburn and irritation. Other conditions include esophagitis, an inflammation of the esophagus, and esophageal strictures, which are narrowings that can make swallowing difficult. Symptoms of esophageal disorders can vary but often include difficulty swallowing, chest pain, and regurgitation of food. Diagnosis typically involves procedures like endoscopy or barium swallow tests. Treatment options may include lifestyle changes, medications, or surgery, depending on the specific disorder and its severity.
