In a 36‑year‑old woman with six months of persistent heartburn despite histamine‑2 receptor antagonist and antacid therapy, and a family history of gastric cancer, what is the most appropriate first step in management?

Avoid NSAIDs and Elevate the Head of Bed

In this 36-year-old woman with persistent heartburn despite H2 blockers and antacids, the most appropriate first step is to escalate to proton pump inhibitor (PPI) therapy while implementing lifestyle modifications—specifically elevating the head of the bed and avoiding NSAIDs—and addressing her family history concern through appropriate risk stratification. 1

Immediate Management: PPI Therapy

• Initiate omeprazole 20 mg (or equivalent PPI) once daily, taken 30–60 minutes before breakfast, for 4–8 weeks. 1, 2, 3 This represents appropriate escalation after H2 blocker failure and is the most effective first-line pharmacological treatment for GERD. 2

• If symptoms persist after 4 weeks of standard once-daily PPI dosing, escalate to twice-daily dosing (one dose before breakfast, one before dinner) for an additional 4–8 weeks. 1, 2

Critical Lifestyle Modifications

A. Elevate Head of Bed – CORRECT ANSWER

• Elevate the head of the bed by 6–8 inches (15–20 cm) using blocks or a wedge for patients with nighttime reflux or regurgitation. 2, 4, 5 This improves esophageal pH profiles and reduces nocturnal acid exposure. 2

• A 20-degree elevation angle has been shown to reduce reflux symptom scores in post-surgical patients and is applicable to GERD management. 5

D. Avoid NSAIDs – CORRECT ANSWER

• Avoid NSAIDs in patients with a history of erosive esophagitis or marginal ulcers, as they increase upper gastrointestinal bleeding risk. 2 While this patient's endoscopic status is unknown, NSAID avoidance is prudent given her refractory symptoms.

• NSAIDs can exacerbate GERD symptoms and delay healing of acid-related mucosal damage. 2

B. Increase Carbs – INCORRECT

• There is no evidence supporting increased carbohydrate intake for GERD management. In fact, limiting fat intake to ≤45 grams per day is recommended as part of an anti-reflux diet. 2

• High-carbohydrate meals, particularly those high in simple sugars, may worsen symptoms in some patients and should not be universally recommended.

C. Decrease Protein – INCORRECT

• There is no guideline recommendation to decrease protein intake for GERD management. 1, 2

• Dietary modifications should focus on identifying and avoiding individual trigger foods (coffee, chocolate, alcohol, spicy foods, citrus, high-fat meals) rather than macronutrient restriction. 2, 4

Additional Essential Lifestyle Measures

• Avoid lying down for 2–3 hours after meals to reduce esophageal acid exposure. 1, 2, 4

• Weight loss if BMI ≥25 kg/m²—this is the single most effective lifestyle intervention for reducing GERD symptoms. 2, 4 A decrease of >3.5 BMI units roughly doubles the odds of symptom resolution. 2

Addressing Family History Concerns

• Her family history of gastric cancer at age 49 warrants consideration for upper endoscopy, particularly if she meets referral criteria. 1

• Referral criteria include: dyspepsia in a patient with a family history of upper gastrointestinal cancer in more than one first-degree relative, or persistent symptoms despite optimized PPI therapy for 8–12 weeks. 1

• Upper endoscopy after 8–12 weeks of optimized twice-daily PPI therapy is indicated when symptoms persist, to identify erosive esophagitis, Barrett's esophagus, strictures, or alternative diagnoses including gastric pathology. 1, 2

• The 2–3-fold elevated cancer risk from family history is modest, but her young age (36 years) and persistent symptoms justify evaluation. 1

Follow-Up Strategy

• Re-evaluate symptom control after the initial 4–8 week PPI trial. 2, 4

• If symptoms remain after 8–12 weeks of optimized twice-daily PPI therapy, perform upper endoscopy to assess for erosive esophagitis, Barrett's esophagus, or gastric pathology. 1, 2

• If endoscopy is normal but symptoms continue, conduct 96-hour wireless pH monitoring off PPI (withhold therapy for 2–4 weeks) to confirm GERD diagnosis. 2

Common Pitfalls to Avoid

• Do not continue empiric PPI therapy indefinitely without objective testing if symptoms persist beyond 3 months of optimized treatment. 2

• Do not assume dietary modification alone will control symptoms—acid suppression with PPIs is essential for documented GERD. 2

• Do not delay endoscopy in patients with alarm features (weight loss, anemia, dysphagia) or those meeting family history criteria for gastric cancer screening. 1, 2
