What It Is, How It Works, and What to Expect
An upper endoscopy, also known as an esophagogastroduodenoscopy (EGD), is a procedure that allows your gastroenterologist to closely examine your esophagus (the tube that carries food from your mouth to your stomach), stomach, and the first part of your small intestine (the duodenum). This minimally invasive test is one of the most effective ways to diagnose, monitor, and sometimes even treat a variety of digestive conditions.
Upper Endoscopy (EGD)
How an Upper Endoscopy Works
During an upper endoscopy, your doctor uses a thin, flexible tube with a small light and high-definition camera on the tip (called an endoscope). This device gently passes through your mouth and throat, capturing detailed images of your upper digestive tract on a monitor. The endoscope can also be used to:
- Take small tissue samples (biopsies) for testing
- Treat bleeding areas
- Remove foreign objects or growths
- Dilate (widen) the narrowed regions of the esophagus
What to Expect Before, During, and After
Before Your Procedure
Our team will review your medical history and provide clear instructions. You’ll typically be asked to avoid eating or drinking for 6–8 hours beforehand. If you take blood thinners or certain medications, we may adjust your dosing.
During Your Procedure
You’ll receive sedation to help you stay relaxed and comfortable. Most patients do not feel discomfort and remember little, if anything, about the procedure. The process usually takes about 15–30 minutes.
After Your Procedure
You’ll recover in our comfortable post-procedure area until your sedation wears off. A mild sore throat is common for a day or so. You’ll need someone to drive you home. Your doctor will share initial findings that day and follow up with biopsy results if applicable.
Conditions Commonly Diagnosed or Monitored with Upper Endoscopy
Gastroesophageal Reflux Disease (GERD)
A long-term condition where stomach acid flows back into the esophagus, causing heartburn, regurgitation, and sometimes damage to the esophageal lining.
Esophagitis
Inflammation of the esophagus, often from GERD, infections, or certain medications, can cause pain or difficulty swallowing.
Barrett’s Esophagus
A precancerous condition where chronic acid exposure changes the lining of the esophagus. Regular monitoring helps detect early signs of cancer.
Esophageal Strictures
Narrowing of the esophagus can cause difficulty swallowing. Endoscopy can identify and often treat this by gently stretching the narrowed area.
Hiatal Hernia
Occurs when part of the stomach pushes upward through the diaphragm, which can sometimes contribute to reflux and other symptoms.
Gastritis
Inflammation of the stomach lining can lead to pain, bloating, and nausea, often caused by infections, alcohol use, or medications.
Peptic Ulcers
Painful sores in the stomach or duodenum are frequently linked to H. pylori infection or prolonged NSAID use.
Helicobacter pylori (H. pylori) Infection
A bacterial infection that can cause ulcers, gastritis, and increase the risk of stomach cancer if untreated.
Celiac Disease
An autoimmune disorder where eating gluten damages the small intestine lining, affecting nutrient absorption.
Esophageal Varices
Enlarged veins in the esophagus, often related to liver disease, can cause life-threatening bleeding.
Upper Gastrointestinal Bleeding
Bleeding anywhere in the upper digestive tract, which may appear as vomiting blood or black, tarry stools.
Swallowing Disorders (Dysphagia)
Difficulty swallowing due to structural narrowing, inflammation, or muscle problems in the esophagus.
Tumors or Cancers
Upper endoscopy can detect and biopsy abnormal growths in the esophagus, stomach, or duodenum for early diagnosis and treatment.
