Endoscopy Q & A

What is involved in getting an endoscopy?

An endoscopy is performed using an endoscope, a flexible tube affixed with a light and camera. The procedure gives Dr. Shim a full view of your digestive tract on a color TV monitor.

If you undergo an upper endoscopy, the endoscope is inserted through your mouth and throat for a picture of your esophagus. The doctor can then evaluate your stomach and the upper part of the small intestine, as well as the esophagus.

For patients needing a lower endoscopy to view the colon, or large intestine, Dr. Shim inserts the endoscope through your rectum.

You do receive sedation during either procedure, but are awake and responsive. Some patients are given a local anesthetic to prevent discomfort at the back of the throat for an upper endoscopy.

What symptoms suggest I need an endoscopy?

Dr. Shim may suggest an endoscopy to evaluate or diagnose any of the following:

  • Stomach pain
  • Ulcers or gastritis
  • Changes in bowel habits, like chronic diarrhea
  • Bleeding in the digestive tract
  • Celiac disease
  • Ulcerative colitis
  • Crohn’s disease
  • Polyps in the colon 


Men and women at high risk for certain gastrointestinal or esophageal conditions should get endoscopies regularly to screen for disease. Dr. Shim may also use an endoscopy to guide a tissue biopsy if suspicious tissue is detected.

How long does an endoscopy take?

An endoscopy is performed on an outpatient basis, meaning you go home the same day. The entire procedure lasts about one hour. 

Dr. Shim lets you know how to prepare for the procedure. In some cases, patients need to fast for a certain amount of time prior.

What is recovery from an endoscopy like?

After the endoscopy, Dr. Shim observes you as the sedation wears off to make sure you don’t have any side effects. You should plan on arranging a ride home as you cannot drive due to the medication.

You may be on pain medications following the procedure, so plan for a low-key day after your endoscopy. Some patients have a sore throat and bloating following an endoscopy. Usually, you can resume your normal diet within a few hours after your procedure.
