Read all directions before you begin. If you are a diabetic taking insulin, contact your personal physician before continuing the preparation. If you are unable to take the provided laxative, castor oil may be substituted. Instructions may be obtained from the Department of Radiology.
A barium enema is an x-ray examination of the lower bowel, or colon, by a water enema containing barium sulfate. Sometimes air will also be used (not usually used with children). This allows the inside of the colon to be seen on a fluoroscope and on x-ray films.
It is necessary that the colon be as empty as possible. For this you will be given a very strong laxative the evening before the study. This will probably cause considerable diarrhea and may cause some discomfort, usually in the late evening or early in the morning. In 10 or 15 percent of the cases, the diarrhea may continue into the afternoon or evening of the day of the examination. If this should be severe enough to require treatment, contact your personal physician. The possibility of such an occurrence should be considered in scheduling an important business or social event the evening before or the day and evening of the examination.
After the examination, it is important to drink as much liquid as is comfortable to replace the fluid you have lost. You may not have a bowel movement other than barium for a day or so. You should have no trouble getting rid of the barium if you are troubled by constipation, a mild laxative of your choice may be advisable.
