The first part of your GI tract is known as upper GI tract which includes the mouth, esophagus, stomach, duodenum (first part of the small intestine), and small intestine.
There are two types of upper GI series:
1. Standard barium upper GI series- it uses only barium during the test.
2. Double-contrast upper GI series- it uses a combination of air and barium to create a detailed view of the stomach lining.
Doctors usually ask the patients not to eat, drink, smoke, or chew gum during the eight hours of the procedure so that a clear upper GI tract is ensured.
The patient may expect to feel bloated or nauseous for sometime after the procedure. They however can resume most normal activities after leaving the hospital.
