rome_iv_functional_dyspepsia: Rome IV Diagnostic Criteria for Functional Dyspepsia

Description

Evaluates the Rome IV criteria for diagnosing Functional Dyspepsia. Diagnosis requires one or both of the main syndromes (Postprandial Distress Syndrome or Epigastric Pain Syndrome) for at least 3 months, with onset at least 6 months ago, and no evidence of organic disease that explains the symptoms.
