Esophagus Tests

How It Feels

When the tube goes through your nose or mouth into your esophagus, you may feel like coughing or gagging. The test may be easier if you try to take slow, deep breaths. You may not like the taste of the lubricant on the tube.

If you have a test that involves adding acid to your stomach, you may have heartburn pain and other symptoms of acid reflux.

After the test is over, your throat may feel sore. However, this should improve within a day or so.
