What happens during esophageal testing?

During esophageal testing or manometry, a healthcare professional will apply a cream to numb the inside of your nostrils. Then a thin, flexible, lubricated tube will be passed through your nose and advanced into your stomach while you swallow sips of water. Mild, brief gagging may occur while the tube is passed through the throat. When the tube is in position, you will be sitting upright or lying on your back while the tube is connected to a computer.

Once the test begins it is important to breathe slowly and smoothly, remain as quiet as possible and avoid swallowing unless instructed to do so. As the tube is slowly pulled out of your esophagus, the computer measures and records the pressures in different parts of your esophagus. During the test, you may experience some discomfort in your nose and/or throat. The test will take approximately 30 minutes to complete and the results will be sent to your doctor's office.
