Barium swallow

A barium swallow is a medical imaging test used to examine the esophagus and upper gastrointestinal tract. During the procedure, a patient drinks a thick liquid called barium, which coats the throat and esophagus. X-ray images are then taken while the barium moves through the digestive system. This allows doctors to see any abnormalities, such as blockages, tumors, or inflammation. The test helps diagnose issues like swallowing difficulties, acid reflux, or other digestive problems, providing valuable information for treatment decisions. It is generally safe, but patients may experience a brief sensation of fullness or discomfort.
