Before Your Upper GI Endoscopy


Your doctor will tell you more specifically what you can expect during the test. 

Some things may include:

  • A nurse will review your medical history, medications and allergies.  
  • You will change into a hospital gown. 
  • Your doctor will review the consent form for the test, answer any of your questions and ask you to sign the form, which says you understand the test being done.
  • An intravenous (IV) line may be started.


During Your Upper GI Endoscopy




The Endoscope


  • The doctor will use an endoscope (a long, thin [about the width of your little finger], flexible tube with a tiny camera and light on the end) to be able to see inside.
  • The endoscope will not block your breathing.


  • During the test, everything will be done to make sure that you are at ease, safe and comfortable.  
  • You may be given medicine to block pain and make you relaxed and sleepy.
  • You may have the back of your throat sprayed with something to numb it to lessen discomfort of the endoscope.
  • A plastic bite block may be placed between your teeth (to protect your teeth and the endoscope). 
  • Once you are fully relaxed, the endoscope will be carefully passed through your mouth, into your esophagus (tube that links your mouth and your stomach) and into your stomach and duodenum, the first section of your small intestine. 
  • In some cases, the doctor may need to do a biopsy (taking a small piece of tissue to look at under the microscope). You will not feel this. 
  • In some cases, the endoscope can be used to treat some problems, like bleeding or narrowing.
  • After the doctor is done looking inside, the endoscope will be removed and you will wake up in recovery as the medicine wears off.


Upper GI Endoscopy – What to Know:
  • An upper GI endoscopy is a test to look at your esophagus (tube that links your mouth and stomach), stomach and small intestine.
  • This test can help find the cause of certain GI health issues.
  • An upper GI endoscopy can also help treat some health issues.
  • You will be given medicine to block pain and make you feel sleepy, so you won’t feel much during the test.
