Endoscopic Swallowing Study

Do you have problems swallowing?

You may have already had a swallowing test with an SLP. You may have been tested in the SLP's office, in the hospital. The SLP may have checked how well you move your mouth muscles and how clearly you talk. You may have tried different foods and liquids.

Sometimes, the SLP needs even more information about how you swallow. You may need another swallowing test—this time using a tube that goes down your throat.

You may hear different names for this test, such as:

  • Endoscopy
  • Endoscopic evaluation of swallowing
  • Fiberoptic endoscopic evaluation of swallowing, or FEES

About Endoscopy

This test helps the SLP see what happens in your mouth and throat when you swallow. Endoscopy lets the SLP see:
  • if food goes into your airway instead of your stomach, called aspiration
  • what parts of your mouth and throat may not work well
  • what kinds of food are safest for you to swallow
  • if certain positions or strategies help you swallow better
