How barium works

Barium works by coating the walls of the food pipe, stomach, and intestines when it enters the digestive tract. Because barium is a heavy, opaque substance, it blocks X-rays from passing through. This creates a bright white outline on imaging screens, which clearly highlights the shape and movement of the digestive organs. As a result, areas that are narrowed, damaged, inflamed, or abnormal become much easier for doctors to spot. It does not get absorbed into the body. It simply passes through after the scan.
