Has the doctor told you to drink a liquid called barium before an X-ray because of a stomach problem? You may have felt a little scared and uncomfortable when you heard the name. You may have thought, "What are you telling me to drink?" But it's actually not as scary as we think. It's a very common, safe test that helps. So today, let's talk about what barium is, why it's used, and what we need to know before and after this test.
Simply put, what is Barium Sulfate ?
Imagine you're looking for a white chair in a dark room. It's hard to find, isn't it? But if you stick a shiny sticker on the chair, it'll be easy to see. Barium does the same thing. Simply put, barium sulfate is
a contrast agent used for special tests . It's usually a thick, white liquid. It's like a drink made by dissolving flour. When you drink it, it travels through your
gastrointestinal tract , which is your
esophagus ,
stomach , and intestines. Then, when you take an X-ray, the barium-stained organs show up very clearly in white. Just like that shiny chair in the dark. This allows the doctor to easily find out if there are
any ulcers , blockages, tumors, or any other problems in your digestive tract.
Things you should definitely tell your doctor before the test
Before having a barium swallow,
it is very important to tell your doctor about your health condition. This information may help determine whether or not to have the test, or whether to have it done differently. See the table below.
| Tell your doctor if you have these conditions. | Why is it important? (Simply) |
|---|
| Bowel blockage | The barium liquid may become stuck and the condition may worsen. |
| If there is blood in the stool orIf there is blood in the vomit | It is dangerous for the barium to travel to other parts of the body, as there may be an injury or hole in the esophagus. |
| If you have difficulty swallowing | Barium liquid can accidentally enter the respiratory tract (lungs). |
| A condition like Inflammatory Bowel Disease (IBD) | Because these diseases can weaken the intestines. |
| Respiratory diseases such as asthma | To be careful about the risk of allergies. |
| Allergies to barium or other medications, foods, or dyes | This is essential to prevent a serious allergic reaction. |
| If you are pregnant or trying to get pregnant | Because X-rays can be harmful to the fetus. |
| If you are a breastfeeding mother | It is important to seek advice from a doctor. |
How do you use this medicine?
This is usually given to you in the hospital, by a medical professional who is in the X-ray room. They will tell you exactly how much to drink and when to drink it. You may be told to drink the entire amount at once, or you may be told to drink it little by little.
The taste of this might be a little strange to you. Some say it tastes chalky. It's also a little thick. But it only lasts for a few minutes, so be brave and drink it.
Do you give this to small children?
Yes, in some special cases, doctors recommend this test for young children. But special precautions are taken. So if your child is scheduled to have this test,
talk to your pediatrician about it thoroughly and find out the details.
What do you do if you accidentally drink too much?
This is usually given in a hospital setting so this is unlikely to happen. However, if you are somehow given this medicine to use at home and accidentally take too much,
contact the National Poisons Information Centre at the Colombo National Hospital immediately. Or
go to the Emergency Department (ETU) of the nearest hospital. This is not a medicine to share with others, it is for you only.
Things to consider after the test
Okay, now you've finished the test. What happens next?
- Water, water, more water! Drink as much water as you can after the test. This is the most important thing. The barium is something that causes constipation until it leaves your body. Drinking plenty of water helps it to be flushed out of your body more easily.
- White stool: Your stool will be white or a light clay-colored for a few days (one, two, maybe three). Don't worry about it at all. It's completely normal. It's your body's way of getting rid of the barium. It will return to its normal color in a few days.
- Dry mouth : Some people may experience dry mouth. To prevent this, drink plenty of water. If your dry mouth persists after a few days, tell your doctor.
Side effects of barium
Like any medicine, barium can cause minor side effects. However, serious ones are very rare. Let's break these down into two categories.
Serious side effects that should be reported to your doctor or ETU immediately
| Allergic Reactions | Skin rash, hives, itching, swelling of the face, lips or tongue. |
| Difficulty breathing | Shortness of breath, making a noise when breathing. |
| Severe stomach pain, blood in the stool, unexplained fever | If these occur after the test, please notify us immediately. |
Side effects that usually go away, but should be reported to the doctor if they persist
| Constipation | Not passing stool for several days even after drinking water. |
| Diarrhea | It may occur rarely in some people. |
| Nausea and vomiting (Nausea, Vomiting) | It can occur during or shortly after drinking. |
| A slight stomach ache or discomfort | The barium can be felt as it passes through the intestines. |
