Your doctor will tell you about any necessary changes to your medicines before the procedure. For safety reasons, you can't drive for 24 hours after the procedure, as the sedatives used during the procedure need time to wear off. You will need to make plans for getting a ride home after the procedure. 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.
Take it easy for the rest of the day after your endoscopy. After receiving a sedative, you may feel alert, but your reaction times are affected and judgment is delayed. When you receive the results of your endoscopy will depend on your situation. If, for instance, your doctor performed the endoscopy to look for an ulcer, you may learn the findings right after your procedure.
If he or she collected a tissue sample biopsy , you may need to wait a few days to get results from the testing laboratory. Ask your doctor when you can expect the results of your endoscopy. Explore Mayo Clinic studies of tests and procedures to help prevent, detect, treat or manage conditions.

An endoscope can also be used to remove a small sample of tissue to be looked at more closely. This is called a biopsy. If the food pipe oesophagus , stomach, or top part of the small intestine need to be looked at, it's known as a gastroscopy. If the bowel needs to be looked at, it's known as a colonoscopy.
