What is happening for patient when upper endoscopy

What can be expected during the Upper Endoscopy?

Your doctor will review with you why upper endoscopy is being performed, whether any alternative tests are available and possible complications from the procedure.  Practices may vary among doctors, but you may have your throat sprayed with a local anesthetic before the test begins and may be given medication through a vein to help you relax during the test.  While you are in a comfortable position on your side, the endoscope is passed through the mouth and then in turn through the esophagus, stomach and duodenum.  The endoscope does not interfere with your breathing during the test.  Most patients consider the test to be only slightly uncomfortable and many patients fall asleep during the procedure.
