What is an Upper Endoscopy?
During an upper endoscopy (also called an esophagogastroduodenoscopy, EGD, or gastroscopy), a gastroenterologist inserts a small, flexible tube through your mouth to inspect your esophagus, stomach, and duodenum (the top part of your small intestine).
Who Needs an Upper Endoscopy?
You may need an upper endoscopy (EGD) if you have heartburn, stubborn abdominal (stomach) pain, trouble swallowing, vomiting, or if a member of your family had esophageal cancer. This procedure can help your gastroenterologist analyze ulcers, inflammation, bleeding, and tumors of your esophagus, stomach, and duodenum.
An EGD is a more advanced tool than x-ray for diagnosing cancer, because it allows your physician to see whether an abnormality is harmless or dangerous.
What is the Prep for and Upper Endoscopy?
You won’t be able to eat or drink anything for about 8 hours before your upper endoscopy procedure, so that your stomach can be absolutely empty. Your doctor will give you detailed directions to follow concerning this fasting based on what time of day your upper endoscopy is scheduled.
