How Acid Reflux is Diagnosed
If your baby spits up a great deal after an hour or two of feeding, or suffers two or more of the above symptoms, see your pediatrician. The doctor may elect to run a number of tests, including an upper GI diagnostic test in which the baby is given some chalky material called barium to drink. A radiologist then traces the barium as it goes through the digestive tract. If the baby is regurgitating the barium into the esophagus, it shows up on the X-ray.
