Barium Enema Test Explained: What to Expect and Why Its Done

In this video, I want to provide you with essential insights about barium enemas, a procedure that may seem daunting but is crucial for diagnosing various bowel conditions. If you've been advised to undergo this test or are simply curious about what it entails, you're in the right place. Understanding the barium enema can help alleviate any anxiety you might have and prepare you for what to expect.

A barium enema is an imaging test that allows doctors to visualize the large bowel, or colon, by using a contrast material called barium. This white liquid is introduced into the bowel through the rectum, making the shape and lining of the bowel visible on X-rays. While barium enemas are not as commonly used today—thanks to advancements like colonoscopy and CT scans—they can still be invaluable in certain situations. They are particularly useful for investigating symptoms such as blood in the stool, changes in bowel habits, or unexplained abdominal pain. Conditions like bowel cancer, polyps, inflammatory bowel diseases (like Crohn's disease and ulcerative colitis), and diverticular disease can be detected through this test.

Preparation for a barium enema is crucial for obtaining clear images. Your healthcare provider will give you specific instructions, but generally, you will need to follow a low-fiber diet for a few days leading up to the test. This means consuming foods like white bread, clear soups, and lean meats. The day before the procedure, you will likely be required to take a strong laxative to ensure your bowel is completely empty. Staying hydrated is also essential, so drink plenty of fluids. I recommend staying home the day before the test, as you may need to use the bathroom frequently. If you have diabetes, are pregnant, or suspect you might be, it's vital to inform your healthcare provider, as the test may not be suitable for you.

On the day of the barium enema, you will arrive at the hospital and change into a gown. You will have the opportunity to discuss the procedure with the medical team, and while you can bring someone for support, they typically cannot accompany you into the X-ray room. During the test, you will lie on your side on an X-ray table. A small injection of a medication called Buscopan may be administered to relax your bowel muscles. A soft tube will then be gently inserted into your rectum, and the barium liquid will be introduced. You may be asked to change positions to help the barium spread, and air may be pumped in to expand the bowel. While this may cause some bloating, it is generally not painful.

The entire procedure usually takes about 30 to 45 minutes. After the test, the tube will be removed, and you can use the restroom immediately. Most patients can go home shortly after, but it's wise to take it easy for the rest of the day. If you received the Buscopan injection, your vision might be slightly blurry, so arranging for someone to drive you home is a good idea. Once home, you may want to stay close to a bathroom for a few hours, as your bowels may still be active. It's normal for your stool to appear pale or whitish for a few days as the barium passes out of your system. Eating and drinking normally is encouraged, but incorporating high-fiber foods and staying hydrated can help prevent constipation.

As with any medical procedure, there are potential risks and side effects associated with a barium enema. While it is generally safe, some individuals may experience nausea, bloating, or mild headaches from the laxatives. Temporary constipation can occur after the test, and in very rare cases, an allergic reaction to the barium may happen. It's crucial to inform your doctor if you think you might be pregnant, as the procedure involves a small amount of radiation—equivalent to what you would naturally encounter over three years. A very rare but serious complication is bowel perforation, which is an uncommon occurrence.

After the procedure, it's essential to monitor your health. Seek medical advice if you experience a high fever, severe or worsening abdominal pain, unusual discharge from the rectum, or persistent constipation. These symptoms could indicate complications that require immediate attention.

In conclusion, a barium enema can be a valuable tool for investigating bowel symptoms and identifying issues like inflammation, growths, or narrowing. While it may not be the first choice for many doctors today, it remains a safe and effective option when necessary.
