Esophageal manometry is a medical test that measures the pressure and movement of the muscles in the esophagus, the tube that connects the throat to the stomach. During the procedure, a thin, flexible tube called a catheter is inserted through the nose or mouth and guided down the esophagus. This catheter has sensors that detect muscle contractions and pressure changes as the patient swallows. The test helps doctors diagnose conditions like gastroesophageal reflux disease (GERD), achalasia, and other swallowing disorders. By understanding how well the esophagus is functioning, healthcare providers can recommend appropriate treatments or interventions for patients experiencing symptoms like difficulty swallowing or chest pain.
