What is an upper endoscopy?

Upper endoscopy is a routine, outpatient procedure in which the inside of the upper digestive system is examined.

The procedure is commonly used to help identify the causes of:

  • Abdominal or chest pain
  • Nausea and vomiting
  • Heartburn
  • Bleeding
  • Swallowing disorders

Endoscopy can also help identify inflammation, ulcers and tumors.

Upper endoscopy is more accurate than X-rays for detecting abnormal growths and for examining the inside of the upper digestive system. The improved accuracy is especially important if you have had upper-digestive-tract surgery in the past.
