Treatment of Acid Reflux Disease
Start with proton pump inhibitors (PPIs) as first-line therapy, taken 30-60 minutes before breakfast for 4-8 weeks, combined with weight loss if overweight—this approach provides superior symptom relief and healing compared to all other medical options. 1, 2, 3
Initial Pharmacologic Management
- PPIs are the cornerstone of GERD treatment and should be initiated as standard-dose once-daily therapy (omeprazole 20mg or equivalent) taken 30-60 minutes before the first meal of the day. 2, 3, 4
- PPIs are superior to H2-receptor antagonists and placebo for both healing erosive esophagitis and achieving symptomatic relief. 2, 3
- Most patients with typical GERD symptoms (heartburn, regurgitation) can be treated empirically without initial endoscopy. 2, 3
- Allow 4 weeks to assess response before escalating therapy. 2, 3
Essential Lifestyle Modifications
Weight loss is the single most effective lifestyle intervention and should be recommended for all overweight or obese patients (BMI ≥25 kg/m²), as this has Grade B evidence for efficacy. 1, 2, 3
Additional evidence-based modifications include:
- Elevate the head of the bed by 6-8 inches for patients with nighttime symptoms or regurgitation when lying down. 2, 3, 5
- Avoid lying down for 2-3 hours after meals to reduce esophageal acid exposure. 1, 2, 3
- Identify and avoid individual trigger foods through detailed dietary history rather than broadly restricting all patients' diets. 2
- Sleep in the left lateral decubitus position rather than right side or supine. 2, 5
Treatment Escalation for Persistent Symptoms
If symptoms persist after 4 weeks of standard-dose PPI:
- Escalate to twice-daily PPI dosing (one dose before breakfast, one before dinner) for more complete acid suppression. 1, 2, 3
- Verify proper PPI timing and adherence—PPIs must be taken 30-60 minutes before meals for optimal efficacy. 3
- Consider adding nighttime H2-receptor antagonist for breakthrough nocturnal symptoms, though tachyphylaxis limits long-term effectiveness. 1, 3
Adjunctive Pharmacotherapy (Personalized to Phenotype)
Do not use adjunctive agents empirically—personalize based on specific symptom patterns: 1
- Alginate antacids for breakthrough post-prandial or nighttime symptoms, particularly in patients with hiatal hernia. 1
- Baclofen for regurgitation or belch-predominant symptoms, though limited by CNS and GI side effects. 1, 6
- Prokinetics only for coexistent gastroparesis—not effective for GERD alone. 1
- Low-dose antidepressants (neuromodulation) for esophageal hypersensitivity or hypervigilance. 1
Avoid metoclopramide as monotherapy or adjunctive therapy due to unfavorable risk-benefit profile, including tardive dyskinesia risk. 2
Long-Term Maintenance Strategy
After achieving symptom control:
- Taper PPI to the lowest effective dose to minimize potential long-term risks while maintaining symptom control. 1, 2, 3
- Exceptions requiring indefinite long-term PPI therapy include: Los Angeles B or greater erosive esophagitis, biopsy-proven Barrett's esophagus, peptic stricture, or severe GERD manifestations (Los Angeles C/D esophagitis, AET >12%, large hiatal hernia). 1
- Periodically reassess the need for continued PPI therapy, as some patients may discontinue or reduce dosing. 2, 3
When to Perform Endoscopy
Perform upper endoscopy in these specific scenarios:
- Lack of response to optimized PPI therapy after 4-8 weeks. 2
- Presence of alarm symptoms (dysphagia, weight loss, anemia, bleeding). 2
- Isolated extraesophageal symptoms (chronic cough, laryngitis, asthma). 2
- PPI therapy continuing >12 months without confirmed GERD diagnosis. 2
Special Considerations for Extraesophageal GERD
Extraesophageal symptoms require more aggressive initial therapy but have lower response rates than typical GERD: 2, 3, 5
- Start with twice-daily PPI for minimum 8-12 weeks. 2, 3, 5
- Implement strict antireflux diet: ≤45g fat/day, eliminate coffee, tea, soda, chocolate, mints, citrus products (including tomatoes), and alcohol. 2, 3, 5
- Consider adding prokinetic therapy if PPI alone is ineffective. 2, 3
- Allow 1-3 months for response assessment, as extraesophageal symptoms respond more slowly. 2, 3
- Address comorbid conditions such as sleep apnea that may exacerbate symptoms. 2, 5
Patients Without Confirmed GERD (Normal Acid Exposure)
If endoscopy shows no erosive disease and pH monitoring demonstrates physiologic acid exposure (AET <4%):
- These patients do not have GERD and likely have a functional esophageal disorder. 1
- Wean off PPI therapy unless symptoms clearly escalate off therapy and improve with PPI (reflux hypersensitivity pattern). 1
- Refer to GI psychologist for cognitive behavioral therapy, esophageal-directed hypnotherapy, and/or pharmacologic neuromodulation. 1
Surgical Referral Criteria
Consider antireflux surgery for carefully selected patients with:
- Objective documentation of persistent GERD on testing (erosive disease or elevated acid exposure). 2, 3, 5
- Failed minimum 3 months of intensive medical therapy (twice-daily PPI, strict diet, lifestyle modifications). 2, 3, 5
- Significant quality of life impairment. 2, 3, 5
- Surgery shows 85-86% improvement or cure in properly selected patients. 2, 5
Common Pitfalls to Avoid
- Don't broadly recommend all lifestyle modifications to every patient—focus on weight loss (if applicable) and individualized trigger avoidance, as evidence doesn't support universal dietary restrictions. 2
- Don't add nocturnal H2RA to twice-daily PPI as standard practice—no evidence supports improved efficacy with this combination. 2
- Don't use higher than standard PPI doses without first optimizing timing and ensuring twice-daily dosing. 2
- Don't assume dietary modification alone will control extraesophageal symptoms—these require pharmacologic therapy. 2
