Treatment of Gastroesophageal Reflux Disease (GERD)
Proton pump inhibitors (PPIs) are the first-line medical treatment for gastroesophageal reflux disease, with twice-daily dosing recommended for patients with severe symptoms or inadequate response to once-daily therapy. 1
Diagnostic Approach
Before initiating treatment, it's important to distinguish GERD from other conditions with similar presentations:
Alarm symptoms requiring prompt endoscopic evaluation:
- Weight loss
- Dysphagia
- Epigastric mass
- Hematemesis 2
In infants and children, consider alternative diagnoses such as:
- Cow's milk protein allergy (overlaps with GERD in 42-58% of infants)
- Neurologic disorders
- Constipation
- Infection 3
Treatment Algorithm
Step 1: Lifestyle and Dietary Modifications
- Weight loss for overweight/obese patients
- Elevate head of bed by 6-8 inches
- Sleep in left lateral decubitus position
- Avoid food intake 2-3 hours before lying down
- Limit daily fat intake to less than 45g
- Avoid trigger foods: coffee, tea, chocolate, mints, citrus, tomatoes, spicy foods, alcohol 1, 4
Step 2: Medical Therapy
First-line:
- PPIs (omeprazole 20-40mg, lansoprazole 15-30mg, esomeprazole 20-40mg, rabeprazole 20mg)
Second-line options:
- H2-receptor antagonists (e.g., ranitidine)
- Can be used for maintenance after initial PPI therapy
- Effective for healing of erosive esophagitis in 84% of patients after 12 weeks 6
Adjunctive therapies:
- Prokinetics (limited evidence supports routine use)
- Baclofen for regurgitation symptoms
- Antacids for breakthrough symptoms 1, 2
Step 3: Evaluation of Treatment Response
After 4-8 weeks of therapy:
- Complete response: Continue therapy and consider step-down to lowest effective dose
- Partial response: Increase to twice-daily PPI if not already prescribed
- No response: Re-evaluate diagnosis with endoscopy and additional testing 7
Step 4: Management of Refractory GERD
For patients with persistent symptoms despite 8-12 weeks of optimized PPI therapy:
- Endoscopy to assess for complications and rule out other diagnoses
- Esophageal manometry to evaluate for motility disorders
- Ambulatory pH or pH-impedance monitoring (off PPI therapy unless previous objective evidence of GERD exists) 2, 1
Step 5: Consider Surgical Intervention
Antireflux surgery (fundoplication) should be considered for:
- Patients with confirmed GERD who remain symptomatic despite optimal medical therapy
- Those with adequate esophageal peristalsis
- Patients unwilling to take long-term PPI therapy 1, 8
Special Populations
Infants and Children
- Most infant reflux resolves spontaneously by 12 months of age
- Parental reassurance and education are often sufficient
- For GERD with erosive esophagitis, esomeprazole is approved for infants 1-12 months 2, 3
Pregnancy
- Start with lifestyle and dietary modifications
- Step-up approach: antacids → sucralfate → H2-receptor antagonists → PPIs for refractory cases 1
Long-term Management
- After initial healing, titrate to lowest effective PPI dose
- Consider periodic attempts at discontinuation
- For patients requiring long-term PPI therapy (>12 months), obtain objective confirmation of GERD
- Surveillance endoscopy every 3-5 years for patients with Barrett's esophagus 1
Common Pitfalls to Avoid
- Misdiagnosis: Not all heartburn is GERD; consider functional disorders, eosinophilic esophagitis, and cardiac disease
- Inadequate PPI dosing: PPIs should be taken 30-60 minutes before meals for optimal effect
- Premature discontinuation: Symptoms may recur if therapy is stopped too soon
- Overlooking lifestyle factors: Dietary and behavioral modifications are essential components of therapy
- Prolonged empiric therapy: Patients with persistent symptoms despite PPI therapy should undergo diagnostic testing rather than continued empiric treatment 2, 9
