Barium

A barium x-ray is a test to look at the outline of any part of your digestive system .  Barium is a white liquid that shows up clearly on an x-ray. Once it is inside the body, it coats the inside of the oesophagus , stomach or bowel. This then shows the outline of the organs on the x-ray. If there is a tumour, it shows up as an irregular outline extending out from the wall of the affected part of the body. Barium liquid does not do you any harm and passes through your digestive system so you don’t absorb
