A barium enema, also known as a lower GI X-ray, is a diagnostic test used to examine the large intestine. It is performed by a radiologist, a doctor who specializes in medical imaging.
How Does the Test Work?
During the test, a white liquid called barium is inserted into the rectum. This liquid coats the inside of the large intestine, allowing the radiologist to take X-ray images of the area.
What Can I Expect Before a Barium Enema?
Before the test, you will be asked to drink a laxative to help clear your bowels. You may also be asked to take an enema to help clear the rectum.
What Can I Expect on the Day of the Lower GI Exam?
On the day of the exam, you will be asked to lie on an X-ray table. The radiologist will then insert a tube into your rectum and slowly inject the barium. You may be asked to change positions during the exam to help the radiologist get better images.
Is a Barium Enema Test Painful?
The test is not usually painful, but you may experience some discomfort.
What to Expect After the Test?
After the test, you may experience some cramping and bloating. You may also have some white or gray stools for a few days.
What Are the Risks of This Test?
The risks of a barium enema are minimal. However, there is a small risk of infection or an allergic reaction to the barium.
When Should I Know the Results of the Test?
The results of the test will usually be available within a few days. Your doctor will discuss the results with you.
When Should I Call My Doctor?
If you experience any pain or discomfort after the test, you should call your doctor.
