What is the initial treatment for Gastroesophageal Reflux Disease (GERD) symptoms?

Initial Treatment for GERD Symptoms

Start with a proton pump inhibitor (PPI) as first-line pharmacological therapy, combined with lifestyle modifications including weight loss for overweight patients and head of bed elevation for nocturnal symptoms. 1, 2

First-Line Pharmacological Treatment

• PPIs are the most effective first-line treatment for GERD, superior to H2-receptor antagonists and placebo for both healing esophagitis and achieving symptomatic relief 1, 2
• Begin with standard-dose PPI once daily: omeprazole 20 mg or lansoprazole 30 mg, taken 30-60 minutes before breakfast to optimally suppress acid production 2, 3, 4
• For patients with typical GERD symptoms (heartburn, regurgitation) without alarm signs (dysphagia, weight loss, anemia, severe pain), empiric PPI therapy is appropriate without initial endoscopy 1, 2
• Assess response after 4 weeks of treatment 1

Essential Lifestyle Modifications

Weight Loss (Strongest Evidence)

• Recommend weight loss for all overweight or obese patients with GERD, as this has the strongest evidence of efficacy and can prevent or delay the need for acid suppression 1, 2
• Weight loss improves both esophageal pH profiles and GERD symptoms 5, 6

Positional Changes

• Elevate the head of the bed by 6-8 inches (15-20 cm) for patients with nighttime heartburn or regurgitation that disturbs sleep 5, 1, 2
• Left lateral decubitus sleeping position improves nocturnal esophageal acid exposure 5
• Avoid lying down for 2-3 hours after meals to reduce esophageal acid exposure by 30-50% 5, 1, 2

Dietary Modifications

• Avoid late evening meals, as food intake before recumbency contributes to reflux 5
• Avoid specific trigger foods on an individualized basis rather than broadly restricting all patients' diets 1, 2
• Common trigger foods include fatty/fried foods, chocolate, coffee, alcohol, citrus, tomatoes, and carbonated beverages, but evidence for universal avoidance is limited 5, 7
• Do not routinely recommend strict avoidance of all potentially refluxogenic foods, as evidence does not support this approach and leads to poor compliance 1

Other Lifestyle Measures

• Smoking cessation and alcohol reduction are recommended, though evidence for symptom improvement is limited 5, 6
• Moderate physical activity is beneficial, but avoid vigorous exercise that increases intra-abdominal pressure 8

Treatment Escalation for Persistent Symptoms

• If symptoms persist after 4 weeks of standard once-daily PPI, escalate to twice-daily PPI dosing (one dose before breakfast, one before dinner) 1, 2
• Consider endoscopy after failed empiric therapy to assess for esophagitis or other pathology 1, 2
• For extraesophageal symptoms (chronic cough, laryngitis, hoarseness) with typical GERD symptoms, start with twice-daily PPI therapy for 8-12 weeks 5, 1
• For extraesophageal symptoms without typical GERD symptoms, consider evaluation for non-GI disorders before initiating PPI therapy 5

Common Pitfalls to Avoid

• Do not add nocturnal H2-receptor antagonist to twice-daily PPI as standard practice, as there is no evidence of improved efficacy with this combination 1
• Do not use metoclopramide as monotherapy or adjunctive therapy due to unfavorable risk-benefit profile, including risk of tardive dyskinesia 1, 2
• Do not use higher than standard PPI doses without first optimizing timing and ensuring twice-daily dosing 1
• Symptom improvement on PPI therapy does not confirm GERD diagnosis, as improvement may result from mechanisms other than acid suppression 5

Long-Term Management

• After initial symptom control, titrate to the lowest effective PPI dose that maintains symptomatic control 1, 2
• Periodically reassess the need for continuous PPI therapy to minimize potential long-term risks 1, 2
• For confirmed erosive esophagitis or Barrett's esophagus, long-term PPI therapy is generally required 2
