Upper Endoscopy

An endoscopy is a medical procedure that lets your doctor examine the lining of the upper part of your gastrointestinal tract, which includes the esophagus, stomach, and the beginning of the small intestine. This is done by inserting a small, flexible tube that has a light source and tiny camera into your mouth and viewing the images on a TV screen.

An endoscopy, or upper GI endoscopy, lets your gastroenterologist, Dr. Shamsi, look for the causes of persistent nausea or upper abdominal pain, swallowing difficulties or vomiting, or sources of bleeding in the upper gastrointestinal tract. Since instruments can be passed through the endoscope, it is also used to get small tissue samples for examination in a lab.

How Do I Prepare for an Endoscopy?

The best and safest examinations are done on an empty stomach. Dr. Shamsi will tell you when to begin fasting, but a period of six hours with nothing to eat or drink is typical. You should also alert Dr. Shamsi or his staff about any medications you are taking, as well as any allergies you have and if you need to take antibiotics before having any dental work done.

You will need to arrange for someone to drive you home after the examination is done. You may not take a taxi or bus home alone.

What Happens During an Endoscopy?

Your gastroenterologist, Dr. Shamsi, will either spray your throat with a local anesthetic or administer a sedative to help you relax, or both. You'll be instructed to lie on your side and the endoscopy will be passed through your mouth and into the areas to be examined. The process isn't painful, and there is no impairment to breathing. Many patients, in fact, even fall asleep.

An hour or so following the procedure the anesthetic will wear off and you can generally be driven home where you can eat and drink normally unless you've been instructed otherwise.

Are There Any Risks With This Procedure?

There are rarely any complications when Dr. Shamsi performs an endoscopy. If any bleeding is caused by a polyp removal or biopsy, it's usually minor and does not require any follow-up or any other treatment. As with any procedure that uses sedatives, there's a possibility of allergic reactions to the medication.
