The American Gastroenterological Association recommends ensuring proper medication timing (30-60 minutes before meals) to maximize efficacy of current omeprazole therapy 1
The American Gastroenterological Association suggests verifying patient compliance with current regimen before making changes 2
Increasing omeprazole from standard once-daily dosing (20mg) to twice-daily dosing is recommended if symptoms persist after 4-8 weeks of properly timed once-daily therapy, with a strength of evidence based on clinical guidelines 2, 1
Consider switching to a more effective acid suppressive agent if symptoms persist despite dose optimization, as recommended by the American Gastroenterological Association 2

The American College of Chest Physicians recommends implementing an antireflux diet with ≤45g fat per 24 hours 3
Eliminating common trigger foods such as coffee, tea, soda, chocolate, mints, citrus products, and alcohol is suggested by the American College of Chest Physicians 3
Discontinuing smoking and limiting vigorous exercise that increases intraabdominal pressure is recommended by the American College of Chest Physicians 3
Elevating the head of bed and avoiding constricting clothing is suggested by the American College of Chest Physicians 4
Maintaining weight loss efforts for overweight or obese patients is recommended by the American College of Cardiology 1

Adding alginate antacids as needed for breakthrough symptoms is recommended by the American Gastroenterological Association 2
Adding an H2-receptor antagonist at bedtime to address nocturnal acid breakthrough is suggested by the American College of Chest Physicians and the American Gastroenterological Association 3, 2
Considering baclofen for regurgitation or belch-predominant symptoms is recommended by the American Gastroenterological Association 2
Adding a prokinetic agent for symptoms suggesting gastroparesis is suggested by the American Gastroenterological Association 2

Considering endoscopy to assess for erosive disease or Barrett's esophagus if symptoms persist despite 8-12 weeks of optimized therapy is recommended by the American Gastroenterological Association and the American College of Gastroenterology 2, 1
Considering 24-hour pH monitoring to confirm GERD diagnosis and assess severity is suggested by the American Gastroenterological Association and the American College of Gastroenterology 2, 1
Evaluating for non-acid reflux which may not respond to acid suppression alone is recommended by the American College of Gastroenterology 1

Considering referral for antireflux surgery or magnetic sphincter augmentation for patients with confirmed GERD who fail optimized medical therapy is recommended by the American Gastroenterological Association 2
Considering transoral incisionless fundoplication as an effective endoscopic option for carefully selected patients is suggested by the American Gastroenterological Association 2
Roux-en-Y gastric bypass can be an effective anti-reflux intervention for obese patients with GERD, as recommended by the American Gastroenterological Association 2

Patients with comorbidities like obstructive sleep apnea may have more difficult-to-control GERD, as noted by the American College of Chest Physicians 3
Certain medications can worsen GERD and should be modified if possible, according to the American College of Chest Physicians 3
Considering neuromodulators or referral for behavioral therapy for patients with functional heartburn or reflux hypersensitivity is recommended by the American Gastroenterological Association 2

Reassessing response to therapy after 4-8 weeks of optimized treatment is recommended by the American Gastroenterological Association 2
Considering step-down to the lowest effective dose once symptoms are controlled is suggested by the American College of Cardiology 1
Periodic reassessment of the need for continued treatment is recommended for patients requiring long-term therapy, as noted by the American College of Cardiology 1
