Greetings of the day
Barium sulphate swallowed by mouth takes the same time to be expelled from the gastrointestinal tract as the gastrointestinal transit time for the normal semi liquid food that is approximately between 16 to 48 hours. It also depends on the consistency of the barium used. Thick consistency barium may take longer to be excreted, because of some amount of retention due to adherence to bowel wall in rectum. Also there may be variation from person to person depending on state of motility and other co-morbid condition.
