What to Expect During the Procedure
You’ll likely receive a local anesthetic spray to numb your throat before the procedure. A doctor will insert a thin, flexible tube (endoscope) through your mouth into your esophagus. The tube has a small camera and light to capture images of your throat, voice box, and esophagus. You may feel mild discomfort or gagging, but it usually doesn’t cause pain. The procedure takes about 15–30 minutes and may involve swallowing air, which can cause bloating afterward.
Preparation Before the Procedure
You may need to fast for a few hours before the procedure, depending on your doctor’s instructions. Avoid smoking or chewing gum to reduce the risk of irritation. Bring any medications you’re currently taking, as you may need to pause certain ones temporarily. Follow your doctor’s specific instructions for the day before the procedure, such as avoiding certain foods or drinks.
What Happens During Recovery
After the procedure, you may feel sore or have mild throat discomfort for a day or two. Swallowing can feel unusual or uncomfortable as your throat heals. Stay hydrated and avoid smoking or spicy foods. You’ll likely have a sore throat, but over-the-counter pain relievers can help if needed. Your doctor may recommend soft foods and rest to ease recovery.
Why This Test Is Done
Doctors perform this test to diagnose or monitor conditions like acid reflux, swallowing disorders, tumors, infections, or inflammation in the throat, voice box, or esophagus. It can also help check for signs of GERD, Barrett’s esophagus, or other gastrointestinal issues that require direct visualization.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This procedure provides critical visual information that standard blood tests or imaging alone cannot. It allows doctors to identify abnormalities early, such as precancerous changes, structural issues, or areas of inflammation that may not be detected by other tests. Early detection can improve treatment outcomes and help prevent complications.
