Esophageal Manometry

Why you might need esophageal manometry
When your esophagus is working properly, the muscles contract to help push food toward your stomach. Valves in your esophagus allow food and liquids to pass down into the stomach and prevent food and gastric acid from coming back up.

Esophageal manometry or an esophageal function study helps diagnose swallowing problems, gastroesophageal reflux disease (GERD) and chest pain. Any of these problems could result from improper function of the esophageal muscles as well as the upper and lower esophageal sphincter.

How an esophageal manometry study is conducted
A specialty-trained nurse numbs your nostril and inserts a thin, pressure-sensitive tube down into your stomach. Once in place, the tube is pulled slowly back into your esophagus. The tube is connected to a computer and records multiple swallows of water while you sit comfortably in a recliner.

Esophageal manometry studies the way your esophageal muscles and valves work. The test only lasts about 20 minutes. You must be totally awake for this procedure so no sedation is given.


  • Do not eat or drink after midnight on the day before the procedure.
  • Medications that cause drowsiness must be stopped two days before testing.
