The document summarizes the radiological procedure for a barium meal exam, which examines the stomach and esophagus. It discusses the preparation, what happens during the exam, results, and potential side effects. The patient is asked not to eat for 6 hours before drinking a liquid containing barium, which is visible on x-rays. X-rays are then taken as the barium travels through the digestive tract. Results are sent to the referring doctor within 3 weeks. Side effects can include temporary white stool and possible constipation, which drinking fluids can help alleviate. The exam allows radiologists to evaluate and diagnose issues like abnormal organ shapes or narrowing.
