How Are GERD And Hiatal Hernia Diagnosed?
Doctors can often diagnose GERD just on the basis of symptoms that individuals with the disease describe. Primary care doctors are very familiar with the symptoms of GERD and can diagnose and treat most cases. Some individuals, however, may require care from gastroenterologists, doctors who specialize in GERD and other diseases of the digestive system.

esophagusand stomach and gives them a white highlighted appearance. The individual having the x-ray usually has to fast several hours in advance, so the stomach is empty and clearly visible.
radiologistwatches the flow of barium as the patient swallows. He checks to see whether the esophagus and stomach are normal. Hiatal hernias, narrowing of the esophagus, ulcers, and other problems may be clearly visible. The radiologist also may tilt the examining table slightly so that the patient’s head is slightly lower than the feet. That position encourages refluxof the stomach contents into the esophagus. Reflux may be visible as a backward flow of the white-colored barium.
Endoscopic examination of the esophagus and stomach is performed by the doctor passing a thin, flexible tube through the mouth and into the esophagus and stomach. The tube is called an
