A barium enema is a test that helps to highlight the large bowel, so it can be clearly seen on an X-ray . During the test,a white liquid called barium is passed into your bowel through your bottom.

A barium enema may be requested by any doctor who thinks you might have a problem with your bowel, including your GP.

The test will usually be carried out at a hospital radiology department by a radiologist or radiographer.
