Diagnosing Dysphagia

In addition to giving you a complete physical exam and taking a detailed medical history, a doctor may use tests to determine what's causing dysphagia. These may include:

  • Videofluoroscopic Swallow Study/Modified Barium Swallow Study - For this test, you drink a special solution that coats the inside of your esophagus, allowing it to show up better on X-rays. Your doctor can then see changes in the shape of your esophagus and can assess the muscular activity.
  • Flexible Endoscopic Evaluation of Swallowing (FEES) - A thin, flexible, lighted instrument (endoscope) is passed down your throat so that your doctor can view your esophagus.
