Endoscopy is a non-surgical procedure used to examine a person’s digestive tract. Using an endoscope—a flexible tube with a light and camera attached to it—your doctor can view images of your digestive tract on a color TV monitor. This allows for a detailed visual inspection of the esophagus, stomach, and duodenum (upper endoscopy) or the colon and rectum (colonoscopy). Endoscopy is a vital tool for diagnosing and, in some cases, treating a wide range of conditions, including ulcers, inflammation, polyps, and early signs of cancer. The procedure is generally safe and well-tolerated, providing crucial insights that help your doctor determine the best course of treatment for your digestive health.
