An upper GI series can be used to help determine the cause of vomitting, abdominal pain, gastroesophageal reflux, etc.
What is Upper Gastrointestinal (GI) Series?
Upper GI series also known as barium swallow is used to detect problems in the upper GI tract with the use of x rays and fluoroscopy. Using x rays a picture is created with help of radiation and a film is recorded on film or on a computer. By using fluoroscopy, an x ray film is created which makes it possible to examine the internal organs and their motion.
In order to make the GI tract properly visible in the x ray film, the patient’s upper GI tract is filled chalky liquid known as barium.
The GI series can be broadly classified into two types:
- A standard barium upper GI series in which barium is used only during the test
- A double-contrast upper GI series in which a combination of air and barium is used to have a clearer picture of the stomach lining.
Why is it Performed?
The upper GI series is performed in order to detect the reason behind:
- Abdominal pain

- Besides these, upper GI series is also used to show:
