Barium Enema Preparation
Your colon must be empty for the barium enema to be accurate. As you prepare for your barium enema, you will have to restrict your diet for a few days beforehand. For example, you might be able to drink only liquids and eat only nonsugar, nondairy foods for two days before the procedure; only clear liquids the day before; and nothing after midnight the night before. A liquid diet means fat-free bouillon or broth, gelatin, strained fruit juice, water, plain coffee, plain tea, or diet soda. To make sure your colon is empty, you will be given a laxative or an enema before the procedure. Your physician may give you other special instructions to help prepare you for your barium enema.
