Overview
Functional heartburn is characterized by typical heartburn symptoms occurring in the absence of erosive esophagitis, often mimicking gastroesophageal reflux disease (GERD) but with different underlying mechanisms 1. It often lacks the typical reflux triggers and may involve visceral hypersensitivity or altered gastrointestinal motility 1.Diagnosis
Symptom Profile: Persistent heartburn without evidence of esophageal mucosal breaks on endoscopy 1.
Exclusion Criteria: Absence of erosive esophagitis on upper endoscopy 1.
Diagnostic Tests: Esophagogastroduodenoscopy (EGD) to rule out structural abnormalities, pH monitoring or impedance testing to assess for reflux events 1.
Grading: No specific grading system mentioned in the provided abstracts 1.Management
First-Line Treatments: Lifestyle modifications including weight management, dietary adjustments (e.g., reducing fatty foods, caffeine, alcohol), and smoking cessation 1.
Pharmacological Interventions: Proton pump inhibitors (PPIs) at standard doses; however, response may be variable compared to GERD 1.
Adjunctive Therapies: Antispasmodics or promotility agents like metoclopramide may be considered for symptoms related to altered motility 1.Special Populations
Pregnancy: Management focuses on conservative measures due to limited evidence on pharmacological interventions; consult guidelines specific to pregnancy 1.
Pediatrics: Limited data; conservative management and parental counseling are emphasized 1.
Elderly: Consider comorbidities and polypharmacy; tailored lifestyle modifications and cautious use of medications 1.
Comorbidities: Management should address coexisting conditions like anxiety or functional dyspepsia, potentially requiring multidisciplinary approaches 1.Key Recommendations
Implement Lifestyle Modifications as first-line therapy for functional heartburn to improve symptom control 1 (Evidence: Strong).
Consider Proton Pump Inhibitors (PPIs) for symptom relief, though efficacy may vary compared to GERD 1 (Evidence: Moderate).
Evaluate and Address Comorbid Conditions such as anxiety or functional dyspepsia, given their potential impact on symptomatology 1 (Evidence: Expert opinion).References
