Radiological images are created by passing small, highly controlled amounts of radiation through the body which capture still images of the body’s internal structures.  A similar imaging method, fluoroscopy, uses x-rays to capture a moving image of an organ while it is functioning.  Fluoroscopy is often the most effective way of viewing the body’s gastro-intestinal tract. A barium meal visualises the upper part of the gastro-intestinal tract (oesophagus and stomach) while a barium enema views the lower gastro-intestinal tract, (colon and bowel).

The Barium meal examines the oesophagus, stomach and the first part of the small intestine.  It is performed to observe digestive function or to detect abnormalities such as ulcers, tumours or inflammation of the oesophagus, stomach or proximal small intestine.  Patients who undergo this procedure often have difficulty swallowing, are complaining of chest and abdominal pain or reflux.  Or have unexplained vomiting or severe indigestion, or blood in their stools indicating internal bleeding.

Preparation for a Barium Meal

The quality of the images will be degraded if the stomach is not empty.  You will be asked not to eat or drink anything for at least 6 hours prior to your scheduled examination time.

The Barium Meal Procedure

A Technologist will position you next to the radiographic machinery that sends real-time images to a television monitor.  You will be given a cup of liquid barium to drink.  The radiologist will note the passage of barium into your oesophagus and stomach on the monitor.  Once the upper gastro-intestinal tract is adequately coated with barium, still images are obtained.

What does the procedure feel like?

The barium has a chalky taste.  You will be asked to hold your breath during the taking of the still images to prevent blurring of the images.  You will be asked to move into different positions while standing, and roll into different position while lying on the examination table.  This ensures that the barium is coating all parts of the oesophagus and stomach.  You may be required to drink additional barium.

The radiologist will ensure the images obtained are adequate for a full evaluation, and will issue your referring doctor with a written report.

The benefits of a Barium Meal

A barium meal is a safe, non-invasive procedure and the results usually provide an accurate analysis of the oesophagus, stomach and duodenum.
