Before the day of the barium enema test, limit your diet to clear liquids. Your doctor will ask you to empty your bowels through the use of cleansing enemas and laxatives. This is called a bowel prep. To avoid any complications or cancellation of the procedure, you need to abstain from eating anything after midnight the night before the procedure. Many doctors recommend limiting your diet to clear liquids the entire day before the test. On the day of the procedure, you can drink clear liquids, such as water, tea, juice, or broth. This is to ensure that your colon is clear of any stool, which could show up in the X-ray images. Be sure to let your doctor know of any bowel movement problems or irregularities before the test.
