Management of Gastroesophageal Reflux Disease (GERD)
Proton pump inhibitors (PPIs) are the most effective first-line pharmacological treatment for GERD, superior to histamine-2 receptor antagonists (H2RAs) and placebo. 1
Initial Treatment Approach
- For patients with typical GERD symptoms without alarm features, a 4-8 week trial of single-dose PPI therapy is recommended without the need for initial endoscopy 1, 2
- Empirical therapy is appropriate initial management for patients with uncomplicated heartburn 3
- PPIs are more effective than H2RAs, which are more effective than placebo for healing esophagitis and providing symptomatic relief 3, 1
- Standard PPI dosing should be taken 30-60 minutes before meals for optimal effect 2
- After symptom control is achieved, PPI should be tapered to the lowest effective dose 1, 2
Lifestyle Modifications
- Weight loss should be recommended for all overweight or obese patients with GERD 3, 1
- Elevation of the head of the bed (6-8 inches) is recommended for patients with nighttime symptoms or regurgitation when recumbent 3, 1
- Avoid lying down for 2-3 hours after meals to reduce esophageal acid exposure 1, 2
- Individualized dietary modifications based on symptom triggers (e.g., avoiding alcohol, coffee, spicy foods if they consistently trigger symptoms) 3, 1
- Limiting fat intake to less than 45g per day as part of an antireflux diet may be beneficial 1
- Weight loss and head of bed elevation are the only lifestyle interventions with evidence supporting improvement in GERD measures 4
Treatment Escalation for Persistent Symptoms
- If symptoms persist despite standard PPI therapy, increase to twice-daily PPI dosing 3, 1
- Consider adding H2RAs as adjunctive therapy, particularly for nighttime symptoms 1, 2
- Adding prokinetic therapy to PPI treatment may be considered for patients with persistent symptoms 3, 1
- Patients whose heartburn has not adequately responded to twice-daily PPI therapy should be considered treatment failures, making that a reasonable upper limit for empirical therapy 3
- Endoscopy should be performed to assess for erosive disease or alternative diagnoses if symptoms persist despite optimized PPI therapy 1, 2
Special Considerations for Extraesophageal GERD
- More intensive therapy, including twice-daily PPI dosing for 8-12 weeks, may be required for patients with extraesophageal GERD symptoms (chronic cough, laryngitis, asthma) 1
- Response rates to PPI therapy are lower for extraesophageal symptoms compared to typical GERD symptoms 1
- A comprehensive treatment regimen including antireflux diet, acid suppression therapy with PPIs, and lifestyle modifications should be implemented for patients with extraesophageal symptoms 3, 1
- Metoclopramide is not recommended as monotherapy or adjunctive therapy in patients with esophageal or suspected extraesophageal GERD syndromes 3
Management of Refractory GERD
- Implementing a strict antireflux diet (≤45g fat/day, no coffee, tea, soda, chocolate, mints, citrus products, alcohol) may be considered for patients with persistent symptoms despite optimized PPI therapy 3, 1
- Addressing comorbid conditions that may worsen GERD (e.g., sleep apnea) is important 3, 1
- For patients with objectively documented GERD that fails maximal medical therapy for at least 3 months, antireflux surgery may be considered 3, 1
- For functional heartburn (normal acid exposure, negative symptom association), consider neuromodulators (tricyclic antidepressants, selective serotonin reuptake inhibitors) 3, 2
Pitfalls and Caveats
- Endoscopy with biopsy is recommended for patients with an esophageal GERD syndrome with troublesome dysphagia 3
- Normal endoscopy findings do not rule out GERD as the cause of symptoms 3
- Periodically reassess the need for continued PPI therapy to minimize potential long-term risks 1, 2
- Patients with presumed extraesophageal symptoms who fail PPI therapy should be investigated for non-GERD causes before proceeding to endoscopy or function testing 3
- Although there is physiologic evidence that exposure to tobacco, alcohol, chocolate, and high-fat meals decreases lower esophageal sphincter pressure, there is limited published evidence of the efficacy of dietary measures for symptom improvement 4
