rome_iv_functional_heartburn: Rome IV Diagnostic Criteria for Functional Heartburn

Description

Evaluates the **Rome IV criteria** for diagnosing **Functional Heartburn**. This is a functional esophageal disorder defined by retrosternal burning pain in the absence of structural, motor, or reflux disease that explains the symptoms. The defining features are refractory symptoms and the lack of a causal link to acid reflux.

Usage

                             no_major_motility_disorder, symptom_onset_ge_6_months,

Value

A list containing:

Diagnosis

"Criteria Met for Functional Heartburn" or "Criteria Not Met".

Arguments

burning_retrosternal_pain

Numeric (0 or 1). Presence of burning retrosternal pain or discomfort. (1 = Yes).

no_symptom_relief_ppi

Numeric (0 or 1). Symptoms are **refractory** to optimal antisecretory therapy (e.g., PPIs). (1 = Yes).

no_gerd_explanation

Numeric (0 or 1). Absence of evidence that gastroesophageal reflux (GERD) is the cause of the symptom (e.g., negative symptom association probability/index and normal acid exposure time on reflux monitoring). (1 = Yes).

no_major_motility_disorder

Numeric (0 or 1). Absence of major esophageal motor disorders (e.g., achalasia) on high-resolution manometry. (1 = Yes).

symptom_onset_ge_6_months
