Question: How Is a Manometry Performed?
Answer: In preparation for the test, you shouldn't have anything to eat or drink for 8 hours before the test.
During esophageal manometry, a thin, pressure-sensitive tube is passed through your mouth or nose, down your esophagus and into your stomach.
When the tube is in your esophagus, you will be asked to swallow. The pressure of the muscle contractions in your esophagus will be measured in different sections of the tube.
The test takes approximately an hour, and after completed, the tube is removed.
