How do doctors perform an upper GI endoscopy ?

A doctor performs an upper GI endoscopy in a hospital or an outpatient center. You will be given a liquid anesthetic to gargle or spray anesthetic on the back of your throat. The anesthetic numbs your throat and calms the gag reflex. The health care staff will monitor your vital signs. In apprehensive patient procedure can be done under sedation or short general anaesthesia which helps you stay relaxed and comfortable during the procedure.
You’ll be asked to lie on your side on an exam table. The doctor will carefully feed the endoscope down your esophagus and into your stomach and duodenum. A small camera mounted on the endoscope will send a video images 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 procedure most often takes between 5 to10 minutes. The endoscope does not interfere with your breathing.
After the procedure you can do your routine activities , join office and also have your food. You may require to stay at the hospital or outpatient center for 1 to 2 hours after the procedure if sedation is given during the procedure.
Results from an upper GI endoscopy are available right away after the procedure. The doctor will share these results with you and also advice the necessary treatment and dietary instructions.
