An upper gastrointestinal (GI) series looks at the upper and middle sections of the gastrointestinal tract. The test uses barium contrast material, fluoroscopy, and X-ray. Fluoroscopy is a kind of X-ray.
An upper GI series is done to find the cause of symptoms such as vomiting, burping up food, trouble swallowing, poor weight gain, bleeding, or belly pain. It's used to find narrow spots or blockages in the upper intestinal tract. The test can also find ulcers, polyps, and pyloric stenosis.
You may have to eat a low-fibre diet for a few days before the test, stop eating for 12 hours before the test, or both. You may also need to take a laxative to help clean out your intestines the evening before the test and stop taking certain medicines.
The test will take about 30 to 40 minutes. If you are also having a small bowel study, the test will take 2 to 6 hours.
