A Barium Enema is an x-ray exam of your rectum and colon. This test helps your doctor detect problems such as a blockage, a tumor, polyps or other disorders.
- A tube is inserted into your rectum.
- Your colon is filled with barium (a liquid that improves the x-ray images).
- You will be asked to move into different positions and hold your breath while x-rays are taken.
- Pressure may be applied to your belly to get the best images.
- The last x-ray will be taken after you go to the bathroom.
- The procedure takes about one hour.
- Bring a list of current medications.
- Please drink a minimum of 6-8 glasses of water in addition to the clear liquids specified in the instructions. Clear liquids you can drink include non-pulpy fruit juices, non-carbonated beverages, tea, coffee, clear soup, plain gelatin (NO fruit), or plain water.
- Do not drink (or use in coffee or tea) any milk, cream, or other dairy products
- Unless directed otherwise by your physician, continue all prescribed medications during this bowel cleansing procedure
- Do not take additional laxatives or antacids
- Day before examination:
- 12:00 pm: Clear liquids only
- 2:00 pm, 3:00 pm, 4:00 pm: Drink 8 oz of clear liquid (total of 24 oz)
