Possible side effects and complications: You may have bloating or cramping after the test,
and will probably feel the need to empty your bowels soon after the test is done. The barium
can cause constipation for a few days, and your stool may appear grey or white until the
barium leaves the body. There is a very small risk that inflating the colon with air could
injure or puncture the colon, but this risk is thought to be much less than with colonoscopy.
Like other x-ray tests, this test also exposes you to a small amount of radiation.
