How is the Test Done?
A thin tube is passed through your mouth or nose and into your stomach. The inside of your nose will be numbed with lidocaine jelly. It will then pass into your stomach. You may gag. This is normal. The tube is pulled slowly back into the esophagus. It is important to tell your doctor if you have symptoms during the test.
When the tube is in the esophagus, you will be asked to swallow. The swallowing wave will be recorded.
The tube is removed when the test is done. You can expect the appointment to take 30 – 45 minutes, the procedure itself will last about 15 minutes.
