What Is Upper Endoscopy?

Upper endoscopy — also called EGD (esophagogastroduodenoscopy) or upper GI endoscopy — is a procedure that uses a thin, flexible tube with a camera to look at the lining of your upper digestive tract: the esophagus, stomach, and duodenum (the first part of the small intestine).

Your NCH gastroenterologist views live images on a monitor and can take tissue samples (biopsies), treat bleeding, or remove polyps when needed — all in one visit.

Unlike a colonoscopy, which examines the large intestine, upper endoscopy focuses on symptoms and conditions above the stomach outlet.

Why Might I Need a Upper Endoscopy?

Symptoms and conditions that may lead your physician to recommend an EGD.

GERD & Chronic Heartburn

Persistent acid reflux, regurgitation, or chest pain that doesn’t respond to medication.

Difficulty Swallowing

Dysphagia, food sticking, or painful swallowing may require direct visualization.

Upper GI Bleeding

Vomiting blood, black stools, or anemia — EGD is the most accurate test for upper tract bleeding.

Ulcers & Inflammation

Stomach or duodenal ulcers, gastritis, and H. pylori evaluation.

Barrett's Esophagus

Monitoring precancerous changes in the esophagus linked to long-term reflux.

Unexplained Nausea or Pain

Persistent upper abdominal pain, nausea, or vomiting when other tests are inconclusive.
