What is a Barium Enema:

A barium enema is a test that is also called a lower GI series. It is an enema that contains a compound (barium) that allows the intestines to be x-rayed.

Reasons for a Barium Enema:

A barium enema is given to find any abnormalities in the intestines. It is used in the diagnosis of colon cancers, IBS, and to see if a cancer has spread to the colon.

What Happens During the Test:

During a barium enema, you will lay down on a table, covered. An enema will be inserted into the rectum. At the tip of the enema, there may be a balloon that will inflate, not allowing the contents to leak out of the rectum. X-rays will be taken, possibly in several positions.

Is is Painful:

Painful, no. Uncomfortable, yes. You will probably feel cramping and may feel like you need to have a bowel movement. Deep breathing exercises are really helpful.

Preparing for a Barium Enema:

The doctor will give you exact instructions. You will probably have to drink a liquid (laxative) the night before to remove any stool contents. You may have to have water enemas and be on a clear liquid diet.

Risks:

The only real risk in having a barium enema is radiation exposure. It is a very low exposure. Doctors will tell you the benefits of having the test certainly outweigh the risk.

How Long Does a Barium Enema Take to Perform:

It generally will take 30-60 muntes.

What to Tell the Doctor:

Always inform the doctor if you are in any pain during or before the procedure. If you are pregnant or think you may be, the doctor absolutely needs to know.
