Upper GI and small bowel series - Risks
GI series; Barium swallow x-ray; Upper GI series
What the risks are:
There is low radiation exposure, which carries a very small risk of cancer. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits.
Pregnant women should usually not have this test. Children are more sensitive to the risks of x-rays.
Barium may cause constipation. Consult your health care provider if the barium has not passed through your system by 2 or 3 days after the exam.
The upper GI series should be done after other x-ray procedures, because the barium that remains in the body may block details in other imaging tests.
