What is an endoscopy?
An endoscopy is a procedure that allows doctors to examine the lining of your gastrointestinal (GI) tract. An upper endoscopy examines your esophagus, your stomach and the first portion of your small intestine.
What to expect during an endoscopy
During the procedure you will be sedated. We will view your digestive tract using a tiny tube, called an endoscope, which has a camera attached. The procedure usually takes 30 to 45 minutes, but patients should fast at least 6 hours before.
Why is an endoscopy performed?
If you have difficulty swallowing, digestive issues, persistent nausea or vomiting, your doctor may refer you for an endoscopy to identify the source of discomfort. An endoscopy can more accurately detect abnormalities in your digestive tract than an X-ray or other methods.
