Functional Chest Pain and Esophageal Hypersensitivity: A Clinical Approach.

Functional chest pain, functional heartburn, and reflux hypersensitivity are 3 functional esophageal disorders defined by the Rome IV criteria. Specific criteria, combining symptoms and the results of objective testing, allow for an accurate diagnosis of these conditions. Management may include medications targeted at optimizing acid suppression or neuromodulation, as well as a host of complementary or alternative treatment options. Psychological and behavioral interventions, such as cognitive behavioral therapy and hypnotherapy, have displayed substantial benefits in the treatment of functional chest pain and functional heartburn. Acid suppression and focused neuromodulation are key evidence-based treatment options for reflux hypersensitivity.
