Description:
A barium enema is an examination of the large bowl (part of the intestines) with the use of a fluoroscope, which uses X-rays to capture a moving image of an organ while it is functioning. These images are taken after the administration of an enema, which fills the colon with barium sulfate, a contrast substance that coats the walls of the colon and enhances the images.

What to Expect During a Barium Enema:
As the barium fills your colon, the radiologist will be taking fluoroscopic films and asking you to turn in various positions. The technologist will then proceed to complete the exam with a series of X-rays. After the exam, you will be allowed to go to the bathroom and expel the barium. You may then be asked to return to the examination room for one or two additional films.

Following this procedure, it is normal for the barium to give a whitish color to your stool for a day or two. Some patients may experience constipation. If this occurs, consult your physician who may tell you to increase your water intake or to take a laxative. A barium enema exam takes approximately 45 minutes to complete.

Patient Preparations for a Barium Enema:
Do not eat or drink after midnight. Laxatives are usually prescribed, which are to be taken the day before the exam so that the lower digestive tract is completely empty. Please bring list of all medications, dosage, and how often they are taken.
