Barium enema is a special x-ray of the large intestine, which includes the colon and rectum.
This test may be done in a health care provider's office or hospital radiology department. It is done after your colon is completely empty and clean. Your provider will give you instructions for cleansing your colon.
During the test:
Your bowels need to be completely empty for the exam. If they are not empty, the test may miss a problem in your large intestine.
You will be given instructions for cleansing your bowel using an enema or laxatives. This is also called bowel preparation. Follow the instructions exactly.
For 1 to 3 days before the test, you need to be on a clear liquid diet. Examples of clear liquids are:
When barium enters your colon, you may feel like you need to have a bowel movement. You may also have:
Taking long, deep breaths may help you relax during the procedure.
It is normal for the stools to be white for a few days after this test. Drink extra fluids for 2 to 4 days. Ask your provider about a laxative if you develop hard stools.
Barium enema is used to:
Barium should fill the colon evenly, showing normal bowel shape and position and no blockages.
