An examination that checks the upper and middle section of the gastrointestinal tract is known as upper gastrointestinal series. Barium contrast material, fluoroscopy, and x-rays are used in the test.
Before the test, a person is made to drink a mix of barium and water. This helps the doctor to examine the movement of barium through esophagus, stomach, and the first part of small intestines on a video screen. Some x-rays are also taken from different angles.
At times, right after the UGI a small bowel follow-through is done to have a look at the rest of the small intestine. When only the throat and esophagus are examined, it is known as esophagram.
Allergic reactions due to the examination take place rarely as barium never gets into the blood.
In rare cases, people may choke or inhale some of the barium liquid into the lungs.
There is a little chance that there would be a blockage in the intestine due to barium or barium would leak into the belly through a perforated ulcer. If a blockage or an ulcer occurs, a special type of contrast material can be used.
Damage to the cells also takes place in very rare conditions. There are very slim chances of tissues being exposed to any radiation.
