Esophageal studies are medical tests that evaluate the structure and function of the esophagus, the tube that connects the throat to the stomach. These studies can help diagnose conditions such as gastroesophageal reflux disease (GERD), esophageal cancer, and swallowing disorders. Common types of esophageal studies include endoscopy, where a flexible tube with a camera is inserted, and manometry, which measures the pressure and movement in the esophagus. These tests are typically performed by a gastroenterologist, a doctor specializing in digestive system disorders. Results from esophageal studies guide treatment options, helping to improve symptoms and overall digestive health.
