Upper Gastrointestinal (GI) Series

A upper gastrointestinal (GI) series  is a group of specialized X-rays that produce high quality images of the upper GI tract. The upper GI tract includes a noninvasive examination of the esophagus, stomach, and duodenum. A upper GI study often utilizes special tools such as a fluoroscopy, a special type of X-ray device, and barium swallow, a type of fluid taken orally to help outline specific areas of the upper GI tract. Some abnormalities are hard to detect by conducting a general X-ray. That is where fluoroscopies and barium come into play. If further studies are required, an upper GI series may include further barium studies or an endoscopy. An endoscopy is performed by a gastroenterologist with the goal of gathering more information after diagnostic imaging studies are completed.

An upper GI series is commonly ordered by a gastroenterologist to rule out abnormalities in the upper GI tract. An upper GI series can detect abnormalities such as ulcers, hernias, inflammation, infections, and much more. A upper GI tract checks the overall health of the esophagus, stomach, and upper intestine.

The extent of the upper GI series ultimately dictates how much preparation is needed. In most cases, no to very little preparation is required. If preparation is required, it relates to fasting prior to your appointment and ceasing certain medications temporarily at your physician's discretion.
