Upper GI Endoscopy

What is Upper Gastrointestinal (GI) Endoscopy?

Upper GI endoscopy is a procedure in which a doctor uses an endoscope a flexible tube with a camera to see the lining of your upper GI tract. One of our providers performs the procedure, most often while you receive light sedation to help you relax.

Also call the procedure endoscopy, upper endoscopy, EGD or esophagogastroduodenoscopy.

Our Physicians use upper GI endoscopy to help diagnose and treat symptoms and conditions that affect the esophagus, stomach, and upper intestine or duodenum.

Upper GI endoscopy can help find the cause of unexplained symptoms, such as:

  • persistent heartburn
  • bleeding
  • nausea and vomiting
  • pain
  • problems swallowing
  • unexplained weight loss
  • Upper GI endoscopy can be used to identify many different diseases:
  • gastroesophageal reflux disease
  • ulcers
  • cancer
  • inflammation, or swelling
  • precancerous abnormalities such as Barrett’s esophagus
  • celiac disease
  • strictures or narrowing of the esophagus
  • blockages

Upper GI endoscopy can check for damage after a person eats or drinks harmful chemicals.

During upper GI endoscopy, a physician obtains biopsies by passing an instrument through the endoscope to obtain a small piece of tissue for testing. Biopsies are needed to diagnose conditions such as:

  • cancer
  • celiac disease
  • gastritis
