A barium swallow is a type of X-ray test that helps doctors examine a patient's upper gastrointestinal (GI) tract, including the back of the mouth and throat (pharynx) and the oesophagus. It is not a laxative. The patient swallows a chalky white substance, barium, which is often mixed with water and sometimes flavoured. Barium is visible on X-rays, so it helps doctors see the patient's upper GI tract and diagnose any conditions that make it difficult to swallow.

Barium swallow tests are used to examine the oesophagus and stomach
A barium swallow test is a type of imaging test that uses barium and X-rays to create images of your upper gastrointestinal (GI) tract. This includes the back of your mouth and throat (pharynx) and your oesophagus, which is a tube that extends from the back of the tongue down to the stomach. Barium is used during a swallowing test to make certain areas of the body show up more clearly on an X-ray. The radiologist will be able to see the size and shape of the pharynx and oesophagus, as well as how you swallow. These details might not be visible on a standard X-ray. Barium is only used for imaging tests for the GI tract.
A barium swallow test may be used by itself or as part of an upper GI series. This series looks at your oesophagus, stomach, and the first part of the small intestine (duodenum). A barium swallow test may be done to look for and diagnose problems in the pharynx and oesophagus. Your doctor may ask you to do a barium swallow to help diagnose any conditions that make it difficult for you to swallow or if they suspect that you have a disorder of the upper gastrointestinal (GI) tract.
The test usually involves the following steps: you may need to remove your clothing and will be given a hospital gown to wear. You will then lie on an X-ray table that can move you from a horizontal to an upright position. You may also be asked to change positions during the test. You will then swallow a drink that contains barium. The drink is thick and chalky and is usually flavoured with chocolate or strawberry to make it easier to swallow. While you swallow, the radiologist will watch images of the barium travelling down your throat to your upper GI tract. You may be asked to hold your breath at certain times. The images will be recorded so they can be reviewed at a later time.
You will probably be asked to fast (not eat or drink) for about eight hours before the test, generally after midnight. You should not have this test if you are pregnant or think you may be pregnant, as radiation can be harmful to an unborn baby. For others, there is little risk to having this test, as the dose of radiation is very low and not considered harmful for most people.

Barium is a white liquid that is visible on X-rays
Barium is used in a procedure called a barium swallow, which is a type of X-ray test. During this procedure, a patient swallows the barium drink, and a radiologist takes X-rays or a fluoroscopy (a type of X-ray "movie") to observe how the barium moves through the pharynx and oesophagus. The barium is visible on the X-rays, appearing as a white substance, and this helps the radiologist to see the size and shape of the pharynx and oesophagus, as well as how the patient swallows.
The barium swallow procedure is used to diagnose conditions that affect the throat, oesophagus, stomach, and the first part of the small intestine (duodenum). These conditions include hiatal hernia, gastroesophageal reflux disease (GERD), structural problems such as polyps or diverticula, muscle disorders, and cancer.
The procedure typically takes place at a radiology facility and lasts about 30 minutes. Patients are advised not to eat or drink anything for six hours before the procedure, and they may be asked to remove clothing and jewellery and change into a medical gown. After swallowing the barium, patients may be asked to move positions and hold their breath at certain times to ensure clear X-ray images.
The barium swallow is considered a less invasive way to examine the upper GI tract than an endoscopy, and it is a useful diagnostic tool for checking for disorders that can be diagnosed with X-rays alone.

The test can help diagnose problems in the food pipe, stomach or bowel
A barium swallow test is a type of X-ray test that helps doctors examine the upper gastrointestinal (GI) tract, including the back of the mouth and throat (pharynx) and the oesophagus. The test can help diagnose problems in the food pipe, stomach or bowel by providing clear images of the upper GI tract.
Barium, a chalky white substance, is ingested by the patient during the test. It is often mixed with water to make a thick drink. As it passes through the body, the barium coats the inside of the upper GI tract, including the food pipe, stomach and bowel, making the outlines of these organs visible on the X-ray images. This allows doctors to identify any problems or disorders in these areas.
A barium swallow test can be particularly useful for diagnosing issues such as muscle disorders that affect swallowing, gastroesophageal reflux disease (GERD), and both cancerous and noncancerous tumours. It can also be used to examine the size and shape of the pharynx and oesophagus, as well as the patient's swallowing motion, which may not be visible on a standard X-ray.
The test usually takes around 30 to 60 minutes and is performed in a hospital's X-ray department. The patient may be asked to change positions during the test, standing for some parts and lying on a tilting table for others, to allow the barium to travel through the body and for the radiologist to capture a selection of images.

Patients may feel nauseous after the test or become constipated
A barium swallow test is a procedure that uses barium and X-rays to create images of a patient's upper gastrointestinal (GI) tract. The test can help diagnose problems in the pharynx and esophagus, and it is often used when a patient is experiencing difficulty swallowing. While the test is generally safe, there are some potential side effects that patients should be aware of. One of these side effects is nausea, which some patients may experience after the test. This is typically mild and should improve as the barium passes through the patient's system.
Another potential side effect of a barium swallow test is constipation. Barium can cause constipation or impacted stool if it is not completely cleared from the body. This can occur if all of the barium does not pass out of the body after the test. To manage this side effect, patients are advised to drink plenty of fluids and eat high-fiber foods to help move the barium through the digestive tract. In some cases, a laxative may be prescribed by a doctor to help with this process.
It is important for patients to be aware of these potential side effects and to contact their doctor if they experience any problems after the test. In addition to nausea and constipation, patients should also seek medical advice if they experience abdominal pain or bloating, or if they have smaller-than-usual stools. These could be signs of more serious side effects, and prompt medical attention is recommended.
To minimize the risk of side effects, patients should follow the instructions provided by their healthcare provider before and after the barium swallow test. This includes adhering to dietary guidelines, such as fasting for a certain period before the test and consuming high-fiber foods and plenty of fluids afterward. By taking these precautions and staying well-hydrated, patients can help ensure that the barium passes through their system without causing any issues.

Barium swallow tests should not be performed on pregnant women
Barium swallow tests are a special type of imaging test that uses barium and X-rays to create images of a patient's upper gastrointestinal (GI) tract. The patient swallows a chalky, white substance known as barium, which is often mixed with water to make a thick drink. The barium coats the inside of the upper GI tract, absorbing X-rays and appearing white on X-ray film. This process helps highlight the organs, their inside linings, and the motion of swallowing on the X-ray images.
While barium swallow tests are a useful diagnostic tool, they are not recommended for pregnant women due to the associated risks. Exposure to radiation during pregnancy, including X-rays, can cause birth defects in unborn fetuses. Therefore, it is essential for patients to inform their healthcare providers if they are pregnant or suspect they might be pregnant before scheduling a barium swallow test.
The potential risks of a barium swallow test include problems from radiation exposure, birth defects, and intestinal issues. While the amount of radiation used in the test may be relatively low, the risks associated with radiation exposure are cumulative and increase with the number of X-ray procedures a person undergoes over their lifetime. As a result, it is crucial for patients to inform their healthcare providers about any previous X-ray procedures or treatments they have received.
In addition to the risks associated with radiation exposure, there are also potential side effects related to the barium itself. If all of the barium is not expelled from the body after the procedure, it can cause constipation or fecal impaction. Patients may be advised to drink plenty of fluids and eat high-fiber foods to help move the barium through their digestive tract. In some cases, a laxative may be prescribed by a doctor to aid in the process.
While there have been studies examining the outcomes of pregnant women inadvertently exposed to barium sulphate in the first trimester, the specific assessment of its safety in pregnant women is still considered scarce. As a result, healthcare providers generally advise against performing barium swallow tests on pregnant women to avoid any potential risks to the fetus.
