What are the management options for a patient with gastroesophageal reflux disease (GERD)?

GERD Management

Start with a 4-8 week trial of once-daily PPI therapy (omeprazole 20 mg taken 30-60 minutes before breakfast) combined with weight loss if overweight/obese and head of bed elevation if nocturnal symptoms are present. 1, 2

Initial Pharmacologic Management

Proton pump inhibitors are the cornerstone of GERD treatment, demonstrating superior efficacy compared to H2-receptor antagonists and placebo for both healing esophagitis and achieving symptomatic relief. 1, 2

First-Line PPI Therapy

• Initiate omeprazole 20 mg once daily, taken 30-60 minutes before the first meal (typically breakfast) for optimal acid suppression. 1, 3
• Continue this regimen for 4-8 weeks to assess response in patients with typical symptoms (heartburn, regurgitation) without alarm features. 1, 2
• No endoscopy is required initially for patients presenting with typical GERD symptoms in the absence of alarm symptoms (dysphagia, weight loss, anemia, bleeding, hematemesis). 1, 4

Dose Escalation Strategy

• If symptoms persist after 4 weeks of standard once-daily dosing, escalate to twice-daily PPI (one dose before breakfast, one before dinner). 1, 2
• For extraesophageal symptoms (chronic cough, laryngitis, globus sensation), start with twice-daily PPI dosing from the outset and continue for a minimum of 8-12 weeks, as these manifestations require more aggressive and prolonged therapy. 1, 2

Maintenance and De-escalation

• After achieving symptom control, taper to the lowest effective dose that maintains relief. 1, 2
• For patients without confirmed erosive esophagitis or Barrett's esophagus, attempt gradual dose reduction according to tolerance. 1
• If PPI therapy extends beyond 12 months without objective confirmation of GERD, consider endoscopy or pH monitoring to document the diagnosis. 1, 2

Lifestyle Modifications

Weight loss is the single most effective lifestyle intervention with the strongest evidence base (Grade B), improving both esophageal pH profiles and symptoms. 1, 2, 5

Evidence-Based Interventions

• Recommend weight loss for all patients with BMI ≥25 kg/m² as this can prevent or postpone the need for acid suppression. 1, 2
• Elevate the head of bed by 6-8 inches for patients with nighttime heartburn or regurgitation, as this improves esophageal pH profiles. 1, 2, 5
• Avoid lying down for 2-3 hours after meals to reduce esophageal acid exposure. 1, 2
• Avoid late evening meals, ensuring at least 2-3 hours between the last meal and bedtime. 1, 2

Dietary Modifications

• Identify and avoid individual trigger foods through detailed dietary history rather than applying blanket dietary restrictions. 1, 2
• Common triggers include fatty/fried foods, chocolate, coffee, alcohol, carbonated beverages, citrus, tomatoes, and spicy foods, but these should be avoided only if they consistently provoke symptoms in the individual patient. 1, 6
• Limit fat intake to ≤45 grams per day for patients with persistent symptoms, particularly those with bile reflux. 1, 2

Interventions Lacking Evidence

• Tobacco and alcohol cessation, while generally recommended for health, have not been proven to improve GERD symptoms or esophageal pH profiles in clinical trials, though they remain reasonable recommendations. 5

Management of Refractory GERD

If symptoms persist despite 8-12 weeks of optimized twice-daily PPI therapy, proceed with diagnostic testing rather than continuing empiric treatment. 1, 2

Diagnostic Evaluation

• Perform upper endoscopy to assess for erosive esophagitis, Barrett's esophagus, or alternative diagnoses (eosinophilic esophagitis, peptic stricture). 1, 2
• If endoscopy is normal, obtain prolonged wireless pH monitoring (96 hours preferred) off PPI therapy to confirm the diagnosis and assess acid exposure. 1, 2
• Combined pH-impedance monitoring can detect both acid and non-acid reflux and establish temporal relationships between symptoms and reflux events. 7

Treatment Optimization

• Verify PPI timing and compliance before concluding treatment failure—PPIs must be taken 30-60 minutes before meals for optimal effect. 1, 2
• Consider adding bedtime H2RA (famotidine) for breakthrough nighttime symptoms, though tachyphylaxis may develop with continued use. 1, 2
• Baclofen can be considered as add-on therapy in selected cases, though it is limited by side effects including somnolence and dizziness. 1

Surgical Intervention

• Laparoscopic fundoplication may be considered for patients with objectively documented GERD who have failed at least 3 months of maximal medical therapy and experience significant quality of life impairment. 1, 2
• Surgery is most appropriate for young, healthy patients with confirmed severe GERD or those at risk for life-threatening complications. 1, 2
• Antireflux surgery improves or cures symptoms in 85-86% of properly selected patients who have failed intensive medical therapy. 2

Special Populations

Pediatric Patients

• Distinguish between physiologic gastroesophageal reflux (GER) and GERD (reflux with troublesome symptoms or complications)—conservative management is appropriate for uncomplicated GER. 7, 2
• Lifestyle changes are first-line therapy: smaller, more frequent feedings, keeping infant upright after feeds, and avoiding overfeeding. 7, 1
• For formula-fed infants with GERD symptoms, consider a 2-4 week trial of extensively hydrolyzed protein or amino acid-based formula if milk protein allergy is suspected. 7, 1
• For breastfed infants, recommend a 2-4 week maternal exclusion diet restricting at least milk and egg. 7
• Use acid suppressants (H2RAs, PPIs) judiciously in pediatric patients due to concerns about inappropriate prescriptions. 7, 2
• Prone positioning should only be used when the infant is observed and awake due to sudden infant death syndrome risk. 2

Elderly Patients

• Standard PPI therapy (omeprazole 20 mg once daily) is appropriate initial management in elderly patients, with the same escalation strategy as younger adults. 8
• Continue concurrent SSRIs without modification, as there is no contraindication to concurrent use with PPIs, and SSRIs may serve as neuromodulators if functional esophageal disorder is present. 8
• Emphasize age-appropriate modifications: small, frequent meals rather than large meals, which is especially helpful in older adults who may have delayed gastric emptying. 8

Alternative Pharmacologic Options

H2-Receptor Antagonists

• H2RAs (ranitidine, famotidine) are less effective than PPIs but more effective than placebo for GERD treatment. 1, 2
• H2RAs can be used as add-on therapy to PPI, particularly for nighttime breakthrough symptoms. 1, 9
• Ranitidine 150 mg twice daily provides symptomatic relief within 24 hours for GERD symptoms. 9

Adjunctive Therapies

• Antacids and alginates provide rapid, short-term relief of breakthrough symptoms. 1
• Adding sodium alginate to PPI can improve symptom resolution in patients with non-erosive reflux disease. 1

Agents to Avoid

• Do not use metoclopramide as monotherapy or adjunctive therapy for GERD due to its unfavorable risk-benefit profile, including the risk of tardive dyskinesia. 2

Critical Pitfalls to Avoid

• Do not continue empiric PPI therapy indefinitely without objective testing if symptoms persist beyond 3 months of optimized therapy. 1, 2
• Do not assume normal endoscopy rules out GERD—many patients with typical symptoms have non-erosive reflux disease requiring pH monitoring for confirmation. 1, 2
• Do not use standard once-daily PPI dosing for extraesophageal symptoms—these require twice-daily dosing from the start. 1, 2
• Do not assess response to therapy too early—allow full 8-12 weeks for extraesophageal symptoms before concluding treatment failure. 1, 2
• Do not broadly recommend all lifestyle modifications to every patient—individualize based on specific symptom triggers and evidence-based interventions only. 1, 2

Long-Term Management Considerations

• PPI therapy is generally safe for long-term use, with safety profiles comparable to placebo for short-term use, though patients should be informed about potential risks and benefits. 1, 8
• For confirmed erosive esophagitis or Barrett's esophagus, long-term PPI therapy is generally required and benefits outweigh risks. 2, 8
• Periodically reassess the need for continued PPI therapy and attempt to use the lowest effective dose to minimize potential long-term risks. 1, 2
• For functional heartburn (normal acid exposure, negative symptom association), consider neuromodulators (tricyclic antidepressants, selective serotonin reuptake inhibitors) rather than continuing PPI therapy. 1
