Prior to Test

If you are allergic to latex or barium, tell your doctor.

Since your intestines must be empty before this test, your doctor may ask you to:

• Eat a clear liquid diet.
• Take laxatives.
• Use a warm water or over-the-counter enema.
• Do not eat or drink anything after midnight.

Description of Test

The doctor will gently insert a well-lubricated enema tube into your rectum. In some cases, you may be given an injection to relax the rectum. Barium will be inserted through the tube. A small balloon at the end of the tube will be inflated. This is to keep the barium inside. The doctor will reposition you several times to ensure that the barium coats the walls of the colon and rectum. A small amount of air will be inserted through the tube. The doctor will take a series of x-rays. After this, the enema tube will be removed.

After Test

After the test, you:

• Will be shown to the bathroom to pass the barium and may be given a laxative
• May feel mild to moderate abdominal cramping and may need to wait before driving home
• Can return to your regular diet unless told otherwise by your doctor
• Can return to regular activities when you feel ready
• Should drink lots of fluids (barium can cause dehydration]]>)
• May have white or gray stool for 2-3 days after the test (due to the barium)

After your test, follow your doctor's instructions.

How Long Will It Take?

About 1-2 hours

Will It Hurt?

You may feel discomfort when the enema tube is inserted. During the test, you may have bloating and severe cramping. You may also feel as if you need to move your bowels.
