….An upper gastrointestinal endoscopy is a procedure that allows your doctor to carefully examine the interior lining of your esophagus, your stomach, and the first part of your small intestine(duodenum) through a thin, flexible viewing instrument called an endoscope.

After the Procedure

  • After the test, you will be observed for 15 minutes (local anesthetic) or for 1 to 2 hours (general anesthetic), until the medications wear off. If your throat was numbed before the test, you should not eat or drink until your throat is no longer numb and your gag reflex has returned to normal.
  • When you are fully recovered, in case of local anesthetic, you can go home. If general anesthetic is used, you will not be able to drive or operate machinery for 12 hours after the test. You should arrange for somebody to take you home.
  • Your doctor will tell you how soon you can resume your usual diet and regular activities. Normally, you can eat after the procedure.
  • Do not drink alcohol for 12 to 24 hours after the test.
