What is upper endoscopy?
Upper endoscopy is a procedure that enables the examiner (usually a gastroenterologist) to examine the esophagus (swallowing tube), stomach, and duodenum (first portion of small bowel) using a thin, flexible tube called the upper endoscope through which the lining of the esophagus, stomach, and duodenum can be viewed using a TV monitor.
How do I prepare for endoscopy?
To accomplish a safe and complete examination, the stomach should be empty. The patient will most likely be asked to have nothing to eat or drink for six hours or more prior to the procedure.
Prior to scheduling the procedure, the patient should inform his or her physician of any medications being taken, any allergies, and all known health problems. This information will help the doctor determine whether the patient may need antibiotics prior to the procedure, and what potential medications should not be used during the exam because of the patient's allergies. The information will provide the individual scheduling the procedure an opportunity to instruct the patient whether any of the medications should be held or adjusted prior to the endoscopy.
Knowledge whether the patient has any major health problems, such as heart or lung diseases, will alert the doctor of possible need for special attention during the procedure.
