When you feel you can do so, start slow by sipping water or other cool liquids. Over the next hours, eat small meals consisting of soft, easily-digestible foods like soups, eggs, juices, pudding, applesauce, etc. You should also avoid consuming alcohol for at least 24 hours after your procedure. Contact your local GI doctor for answers to more specific questions or schedule an appointment with one of our gastroenterologists.
March 14, John McAlpin. To see your upper GI tract clearly, your doctor will most likely ask you not to eat or drink up to 8 hours before the procedure.
A doctor performs an upper GI endoscopy in a hospital or an outpatient center. Before the procedure, you will likely get a sedative or a medicine to help you stay relaxed and comfortable during the procedure. The sedative will be given to you through an intravenous IV needle in your arm. In some cases, the procedure can be done without getting a sedative. You may also be given a liquid medicine to gargle or a spray to numb your throat and help prevent you from gagging during the procedure.
The health care staff will monitor your vital signs and keep you as comfortable as possible. The doctor will carefully pass the endoscope down your esophagus and into your stomach and duodenum. A small camera mounted on the endoscope will send a video image to a monitor, allowing close examination of the lining of your upper GI tract. The endoscope pumps air into your stomach and duodenum, making them easier to see. The upper GI endoscopy most often takes between 15 and 30 minutes.
The endoscope does not interfere with your breathing, and many people fall asleep during the procedure. You should follow all instructions. Some results from an upper GI endoscopy are available right away. Your doctor will share these results with you or, if you choose, with your friend or family member. A pathologist will examine the samples of tissue, cells, or fluid that were taken to help make a diagnosis.
Biopsy results take a few days or longer to come back. Serious complications from this procedure are uncommon. There is a small chance of a hole forming in the stomach, duodenum, or esophagus from the scope moving through these areas. There is also a small risk of bleeding at the biopsy site. Before your procedure, you will need to have an empty stomach. Additionally, if you take any blood-thinning medication, your physician may request that you stop using for days before the test.
The procedure usually takes 30 to 45 minutes. Before the procedure, anesthesiology will give you medication through a vein to help you relax and better tolerate any discomfort from the procedure.
The procedure will begin with you lying on your left side. The scope will be passed through your mouth into the throat, stomach, and small intestine.
