Esophageal manometry measures your esophagus’s muscle contractions and muscle pressure. Your doctor may recommend esophageal manometry if you experience chest pain, heartburn or have difficulty swallowing.
What to Expect When You Have Esophageal Manometry
Before the procedure, your doctor will discuss your medical history and any medications or allergies. They may also recommend fasting for a period of time before the test.
During esophageal manometry, a doctor will apply a cream to numb the inside of your nostrils. Then, they will pass a thin, flexible, lubricated tube through your nose and down into your stomach while you swallow sips of water.
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 will measure and record the pressure 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.
