A doctor usually establishes the diagnosis of GERD by performing an evaluation of symptoms. A doctor will prescribe tests to confirm GERD as people with chronic and severe heartburn. Examinations may include a series of radiographs of the stomach to detect other possible problems (eg. The presence of peptic ulcers). A blood or breath test may be performed to rule out the presence of a bacterium called Helicobacter pylori.
There are also tests that measure the pH (acidity) of the esophagus and the internal pressure of the lower esophageal sphincter (LES). The most important diagnostic tool remains the Endoscope, an optical tube that is inserted into the throat and allows the doctor to see inside the esophagus (a procedure called endoscopy).
People who have heartburn regularly or daily for 5 years or more should perform diagnostic tests Barrett's esophagus. Many physicians regularly examine people with this condition to identify changes that could eventually turn into cancerous tumors.
