it's time to see your doctor if you have acid reflux symptoms two or more times a week or if medications don't bring lasting relief. symptoms such as heartburn are the key to the diagnosis of acid reflux disease especially if lifestyle changes antacids or acid-blocking medications help reduce these symptoms. your doctor may order one or more tests to confirm a diagnosis and check for other problems: barium swallow (esophagram) can check for ulcers or a narrowing of the esophagus. esophageal manometry can check the function of the esophagus and lower esophageal sphincter. endoscopy can check for problems in your esophagus or stomach. a biopsy may be taken during endoscopy to check samples of tissue under a microscope for infection or abnormalities.
