Upper GI Endoscopy


Upper GI Endoscopy

Welcome to our health education library. The information shared below is provided to you as an educational and informational source only and is not intended to replace a medical examination or consultation, or medical advice given to you by a physician or medical professional.

Upper GI endoscopy allows your doctor to look directly into the beginning of your gastrointestinal (GI) tract. The esophagus, stomach, and duodenum (the first part of the small intestine) make up the upper GI tract.

Upper GI Endoscopy

During endoscopy, a long, flexible tube is used to view the inside of your upper GI tract.


Before the Exam

Follow these and any other instructions you are given before your endoscopy. If you don't follow the doctor's instructions carefully, the test may need to be cancelled or done over.

  • Do not eat or drink anything after midnight the night before your exam. If your exam is in the afternoon, drink only clear liquids in the morning, and do not eat or drink anything for 6 hours before the exam.
  • Bring your x-rays and any other test results you have.
  • Because you will be sedated, arrange for an adult to drive you home after the exam.
  • Tell your healthcare provider before the exam if you are taking any medications or have any medical problems.

The Procedure

  • You lie on the endoscopy table.
  • Your throat may be numbed with a spray or gargle. You are given sedating (relaxing) medication through an intravenous (IV) line.
  • You swallow the endoscope. This is thinner than most pieces of food that you swallow. It will not affect your breathing. The medication helps keep you from gagging.
  • Air is inserted to expand your GI tract. It can make you burp.
  • The endoscope carries images of your upper GI tract to a video screen. If you are awake, you may be able to look at the images.
  • After the procedure is done, you rest for a time. An adult must drive you home.
