Based on your past medical history, physical exam and current symptoms, your doctor is recommending a procedure called esophago-gastro-duodenoscopy, also called upper endoscopy or EGD.
This procedure may be used as a screening check, or to find out why you are having specific symptoms.
These might include: upper abdominal pain, such as heartburn, nausea, vomiting, difficult or painful swallowing, anemia, diarrhea or bleeding.
Upper endoscopy is used by your doctor to gain more information about your esophagus, stomach, and small intestine. Your doctor can look at the insides of these structures by placing an endoscope, which is a small bendable tube that acts like a video camera, into your throat. If anything unusual is found by your doctor, like growths or foreign bodies, the endoscope may also be used to treat them.
At this time, your doctor feels that upper endoscopy is necessary.
