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 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 may include difficulty swallowing, chest pain, and heartburn. Diagnosis often involves procedures like endoscopy or barium swallow tests. Treatment options vary depending on the specific disorder and may include lifestyle changes, medications, or surgery.
