A single-contrast study usually takes 30 to 45 minutes,

drink plenty of liquids to replace those you have lost and to help flush the
remaining barium out of your system. Your bowel movements may look white or

How It Feels
A barium enema procedure can be
uncomfortable and tiring, but usually it does not last very long.
Many people report that the preparation and bowel cleaning are the hardest parts of the test. The laxative may have an unpleasant taste, and the

sore during the process. Warm
sitz baths or a local anesthetic salve, such as
Preparation H, can help ease this discomfort.
