This is a series of x-rays of the esophagus, stomach, and the first part of the small intestine called the duodenum. Together, the esophagus, stomach, and duodenum are called the upper gastrointestinal (GI) tract, or upper digestive system. The x-rays are taken during and after drinking contrast material called barium . The barium solution is a thick, white, chalky, milkshake-like liquid. It coats the inside lining of your GI tract. This makes the GI tract show up better on the x-ray.
An upper GI series may be done if you have:
An upper GI series can help detect:
Some people may have an allergic reaction to the barium or have difficulty keeping it down.
You will remove all jewelry and wear a hospital gown. You will drink the barium solution. As you drink the barium, the radiologist will take x-rays of your chest and abdomen. The doctor may also give you bits of food to eat with barium on them. You may have to change positions frequently during the test.
If your doctor wants to look at more of your intestines, a small bowel follow-through may be done. This means that x-ray pictures are taken every 15-30 minutes while the barium travels further down the intestines.
You may eat and drink as usual. Drink plenty of fluid. The barium will slowly pass through your system on its own.
You may have some white-colored stool or constipation after the test.
An upper GI series can take 30 minutes-2 hours. A small bowel follow-through can take 1-4 hours.
