3. Are symptoms adequate to diagnose GERD?

The diagnosis of GERD based upon symptoms alone is correct in only approximately two-thirds of patients.  This is because the symptoms are not specific for GERD and can be caused by other abnormalities such as esophageal cancer, pyloric stenosis, peptic ulcer disease, gallstones, gastritis and coronary artery disease.

This fact underscores the need for objective diagnosis prior to deciding on treatment.
