Barium Tests

Overview

A barium test is an imaging procedure that uses a special liquid called barium to make your digestive tract visible on X-rays. The liquid coats the inside of your throat, stomach, or intestines, highlighting their shape and movement. There are different types of barium tests, such as a barium swallow (throat and stomach), barium meal (stomach), and barium enema (large intestine). This article explains what happens during a barium test and what to expect.

Barium tests are common and have been used for many years. They are often replaced by other imaging methods like CT scans, but are still widely used when a detailed view of the digestive tract is needed.

Barium tests are used for people of all ages, from children to older adults. Your doctor may suggest one if you have symptoms such as difficulty swallowing, unexplained stomach pain, changes in your bowel habits, or blood in your stool.

Symptoms

Common symptoms

• A chalky taste in your mouth when you drink the barium.
• You may feel full, bloated, or have mild stomach cramps.
• Your stool (poo) may be white or pale for a day or two after the test.

Symptoms in children

• Children may be given a flavored barium liquid to make it easier to swallow.
• They may feel anxious about the X-ray machine, but the test itself is not painful.
• Parents or guardians are usually allowed to stay with the child during the test.

Symptoms in older adults

• Older adults may be more likely to have trouble swallowing the barium, so the test team will monitor them closely.
• They may need someone to help them move to the X-ray table.
• Older adults are also more likely to become constipated after the test, so drinking plenty of water is important.

Causes

Main causes

• Difficulty swallowing or pain when swallowing
• Persistent heartburn or acid reflux symptoms
• Unexplained abdominal pain or cramping
• Changes in bowel habits, such as diarrhea or constipation
• Blood in the stool
• Unexplained weight loss

Risk factors

• A history of bowel obstruction or perforation
• Diabetes (because you may need to adjust your meals and medication before the test)
• Difficulty swallowing due to a neurological condition
• A known allergy to medications or contrast materials
• Severe constipation or a recent colon surgery

When to see a doctor

See a doctor urgently if:

• Contact your doctor right away if you experience severe symptoms as listed in the emergency section, or if you are unable to pass any stool or gas for 48 hours after the test.

Book a routine appointment if:

• Make an appointment to discuss any testing you might need for ongoing digestive symptoms. If your doctor has already referred you for a barium test, follow their instructions about how to prepare.

Diagnosis

A barium test is a diagnostic procedure, not a treatment. It gives your doctor a clear X-ray picture of your digestive tract to help find the cause of your symptoms. The test takes about 30 minutes to over an hour, depending on the type.

Tests that may be done

• Barium swallow – focuses on the throat and esophagus
• Barium meal – looks at the stomach and the first part of the small intestine
• Barium follow-through – watches the barium as it moves through the small intestine
• Barium enema – examines the large intestine (now less common, but still used sometimes)

What to expect at your appointment

Before the test, you'll change into a hospital gown and may be asked to remove metal items. You'll drink the barium liquid or have it given through a tube in your rectum for an enema. The radiographer will take a series of X-rays while you change positions. You may feel a strange taste or a feeling of fullness. The staff will guide you through it step by step.

Treatment

After the test, you can usually go home right away. The barium will pass through your body naturally and come out in your stools within a day or two. There is no specific 'treatment' for the test itself, but you can help your body get rid of the barium.

Self-care at home

• Drink extra fluids, like water, for a few days to help prevent constipation.
• Eat foods with fiber, such as fruits and vegetables, to keep your bowels moving.
• If you feel constipated, talk to your pharmacist or doctor about a gentle laxative – do not use one without advice.

Medical treatments

The barium often needs no medical treatment. If a problem is found on the test, your doctor will discuss the next steps with you. This may include further tests or treatments. Your doctor will explain any results and options clearly.

When is surgery considered?

Surgery is not needed for a barium test itself. If the test reveals a problem that requires surgery, your doctor will refer you to a specialist for that decision.

Living with this condition

Most people can resume their normal activities immediately after a barium test. You may want to rest for a few hours if you feel tired or have mild cramps.

Lifestyle tips

• Plan a light meal after the test if allowed.
• Ask someone to drive you home if you feel unsteady from fasting or sedatives (if any).
• Keep a record of any symptoms you have after the test and share them with your doctor.

Diet and exercise

After the test, drink plenty of water and eat high-fiber foods to help your body eliminate the barium. Gentle walking can help stimulate your bowels. Avoid lying down immediately after the test if you had a barium meal or swallow, to help the barium move down.

Mental health and emotional wellbeing

Waiting for test results can be stressful. It's important to talk about your feelings with your doctor or a trusted friend. If you feel very anxious, ask your healthcare team for support.

Prevention

You don't need to 'prevent' a barium test. It is a safe procedure. However, you can reduce the risk of discomfort by following all preparation instructions carefully, such as fasting and emptying your bowels if directed.

Complications

If left untreated

• Constipation or a feeling of blockage (a barium impaction) is rare but possible, especially if you don't drink enough fluids.
• In rare cases, barium can leak into the surrounding tissue if there is a hole in the bowel – this is a medical emergency.
• Some people may have an allergic reaction to the barium or the flavoring – this is uncommon.

Long-term outlook

For most people, a barium test is straightforward and does not cause lasting problems. The results can help your doctor find the cause of your symptoms and guide you toward effective care. Any side effects, like mild constipation, usually pass within a day or two.
