If you have been diagnosed with gastroesophageal reflux disease (GERD) based on your symptoms or through objective reflux testing, there are several approaches available to help manage your symptoms.

The two most common tests done to confirm a diagnosis of acid reflux, or to explore problems with similar symptoms, include a 24 hour pH probe exam and an upper GI series.
