Why This Test Is Done
Your doctor may recommend this test if you have symptoms like persistent acid reflux, unexplained weight loss, difficulty swallowing, or unexplained bleeding in the throat. It can also be done to investigate symptoms like chronic cough, chest pain, or unexplained anemia. A biopsy helps determine the cause of symptoms that don’t improve with standard treatments.
What to Expect Before the Test
You may be asked to fast for a few hours before the procedure, but this isn’t always necessary. Avoid smoking and alcohol for 24 hours beforehand. Bring any medications you’re currently taking, as some may need to be adjusted or temporarily stopped.
The Procedure
A small sample of tissue will be taken from your esophagus using a thin, flexible tube with a camera (endoscope). You’ll likely feel mild discomfort but no pain. The procedure usually takes about 15–30 minutes and is done under mild sedation to keep you relaxed.
What Happens After the Test
You’ll be monitored briefly in a recovery area before being allowed to go home. You may experience mild soreness or discomfort in your throat. Avoid eating or drinking until you’ve been cleared by your doctor, and follow any specific instructions for diet or activity.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps diagnose conditions like Barrett’s esophagus (a precancerous change), esophageal cancer, infections (e.g., Candida or Helicobacter pylori), or inflammatory diseases (e.g., eosinophilic esophagitis). Early detection can guide treatment and improve outcomes.
