What Is An Upper Endoscopy?

An endoscopy is a medical procedure that allows a gastroenterologist to view the inside of your gastrointestinal tract, which includes the esophagus, stomach, and small intestine.

It involves using a thin, flexible tube called an endoscope that has a tiny camera and light installed, which allows to view images on a video monitor.

Why is Upper Endoscopy Done?

Gastroenterologists can recommend an endoscopy to be scheduled for 3 main reasons. Usually, its to diagnose symptoms, monitor illnesses, or treatment of disease.

Endoscopies are very effective for screening and preventing cancer as they can be used to obtain small tissue samples to observe between benign and malignant (cancerous) tissues.

Its recommended to discuss why you need to undergo an endoscopy beforehand, so you also understand the importance, goals, and expectations for the procedure.


What Symptoms Does Endoscopy Help To Evaluate?

Aside from heartburn, endoscopy may also be used for:

  • Inflammation, ulcers, and tumors
  • Upper abdominal pain
  • Bleeding
  • Swallowing disorders
  • Nausea and vomiting
  • Stomach bleeding

Upper endoscopy can be more accurate than X-rays or other imaging for detecting abnormal growths and for examining the inside of the upper digestive system.

How do you Prepare for Endoscopy?


  • A gastroenterologist will guide you step by step on what pre-measures to take and abide by.
  • You may be asked to sign a form that gives you consent and permission for the procedure.
  • If you take any medications it’s recommended to mention this before your prep starts.
  • You will be asked to not drink or eat anything on the day of your test.
  • If you have a history of any bleeding disorders, you should let your GI doctor know.
  • You may be asked to take a laxative and enema or have to drink a certain fluid to help clean out your bowels.


  • You will be asked to remove clothing, jewelry, or any objects that can obstruct the procedure, and change into something more comfortable and loose, such as a gown
  • You won’t feel any discomfort throughout your procedure as you will be sedated
  • Tissue samples may be collected for a biopsy to test for diseases and other conditions or cancers affecting the digestive system.
  • After numbing your throat and once you feel relaxed after your sedative, a thin flexible tube will be inserted in your mouth and throat until it reaches your duodenum
  • Once your gastroenterologist is satisfied he or she has performed the necessary procedure, the tube will be taken out of your mouth.


  • Following your procedure, you will be observed. Once you are alert, stable, and breathing fine again, you can be discharged.
  • You should have someone drive you home afterward as you’ll still be feeling drowsy.
  • If you feel gassy or pain in your throat for a few days after your discharge, this is normal.
  • You can return to your normal activities and diet the next day unless otherwise instructed
  • If you experience any chills or fever, swelling, bleeding, black or bloody stools, trouble swallowing or if your chest pain gets worse, contact your gastroenterologist immediately.
