What to Expect Before the Procedure
You may be asked to avoid eating or drinking for several hours before the procedure, depending on your doctor’s instructions. Some patients receive a mild sedative to help relax during the exam. Your doctor will explain the steps and any preparations needed beforehand.
During the Procedure
The doctor will insert a thin, flexible tube (endoscope) through your nose or mouth to visualize your throat, mouth, and nearby areas. If a biopsy is needed, small tissue samples will be taken and sent to a lab for analysis. The procedure usually takes 15–30 minutes.
Aftercare and Recovery
After the procedure, you may feel sore or have mild discomfort in your throat. Avoid talking, swallowing hard, or eating for a short time. Your doctor will provide specific instructions for follow-up, including any restrictions on activity or diet.
Why This Test Is Done
