What is Upper Endoscopy?
Why is Upper Endoscopy done?
Upper endoscopy helps your doctor evaluate symptoms of persistent upper abdominal pain, nausea, vomiting or difficulty swallowing. It’s the best test for finding the cause of bleeding from the upper gastrointestinal tract. It’s also more accurate than X-ray films for detecting inflammation, ulcers and tumors of the esophagus, stomach and duodenum.
Your doctor might use upper endoscopy to obtain a biopsy (small tissue samples). A biopsy helps your doctor distinguish between benign and malignant (cancerous) tissues. Remember, biopsies are taken for many reasons, and your doctor might order one even if he or she does not suspect cancer. For example, your doctor might use a biopsy to test for Helicobacter pylori, the bacterium that causes ulcers.
Your doctor might also use upper endoscopy to perform a cytology test, where he or she will introduce a small brush to collect cells for analysis.
Upper endoscopy is also used to treat conditions of the upper gastrointestinal tract. Your doctor can pass instruments through the endoscope to directly treat many abnormalities – this will cause you little or no discomfort. For example, your doctor might stretch (dilate) a narrowed area, remove polyps (usually benign growths) or treat bleeding.
What preparations are required?
Tell your doctor in advance about any medications you take; you might need to adjust your usual dose for the examination. Discuss any allergies to medications as well as medical conditions, such as heart or lung disease.

What happens during upper endoscopy?
What happens after upper endoscopy?
Your physician will explain the results of the examination to you, although you’ll probably have to wait for the results of any biopsies performed.
If you have been given sedatives during the procedure, someone must drive you home and stay with you. Even if you feel alert after the procedure, your judgement and reflexes could be impaired for the rest of the day.
What are the possible complications of upper endoscopy?
Although complications after upper endoscopy are very uncommon, it’s important to recognize early signs of possible complications. Contact your doctor immediately if you have a fever after the test or if you notice trouble swallowing or increasing throat, chest or abdominal pain, or bleeding, including black stools. Note that bleeding can occur several days after the procedure.
