Management of Epigastric Pain (Presumed Dyspepsia)
Initial Risk Stratification and When to Refer for Endoscopy
For patients without alarm features and age <55 years, proceed directly to H. pylori testing and empirical PPI therapy without endoscopy. 1, 2
Urgent endoscopy is required for:
- Patients ≥55 years with dyspepsia AND weight loss 1, 2
- Patients >40 years from high gastric cancer risk areas or with family history of gastro-oesophageal cancer 1, 2
- Any age with dysphagia 1, 2
- Patients ≥60 years with abdominal pain and weight loss require urgent CT scan to exclude pancreatic cancer 1, 2
Non-urgent endoscopy is considered for:
- Patients ≥55 years with treatment-resistant dyspepsia 1, 2
- Patients ≥55 years with dyspepsia plus raised platelet count, nausea, or vomiting 1, 2
Initial Laboratory Testing
Obtain a full blood count in all patients ≥55 years with dyspepsia. 1, 2
Obtain coeliac serology in all patients with overlapping IBS-type symptoms (bloating, altered bowel habits). 1, 2
H. Pylori Testing Strategy
Test all patients with dyspepsia for H. pylori using either 13C-urea breath test (preferred) or stool antigen test—both have >90% sensitivity and specificity. 1, 3, 2
Critical testing considerations:
- Avoid whole blood serological tests as they lack adequate sensitivity and specificity 1
- The urea breath test has 88-95% sensitivity and 95-100% specificity 4
- The stool antigen test has 94% sensitivity and 92% specificity 4
- Testing during acute bleeding may yield false-negatives, requiring repeat testing if initially negative 4
If H. pylori positive:
Provide eradication therapy immediately with standard triple therapy: PPI twice daily + amoxicillin 1000mg twice daily + clarithromycin 500mg twice daily for 14 days. 3, 4
This eliminates peptic ulcer mortality risk and prevents gastric adenocarcinoma, though it may not resolve all dyspeptic symptoms. 1, 3, 2
Confirmation of successful eradication is only necessary in patients at increased risk of gastric cancer. 1
Proton Pump Inhibitor Therapy
For H. pylori-negative patients or persistent symptoms after eradication:
Start standard-dose PPI (omeprazole 20mg or equivalent) once daily, taken 30-60 minutes before a meal, for 4-8 weeks. 1, 3, 2, 5
All commercially available PPIs have similar efficacy for symptom control, and PPIs are superior to H2-receptor antagonists, which are superior to placebo. 3
If symptoms persist after 4-8 weeks of once-daily PPI:
Increase to twice-daily dosing (morning and evening) before meals, and continue for an additional 4-8 weeks. 3
Symptom-based approach:
- For ulcer-like dyspepsia (epigastric pain predominant): Full-dose PPI is first choice, with response confirming acid-related nature 1, 3
- For dysmotility-like symptoms (bloating, fullness, early satiety): Add a prokinetic agent, though availability and side effects limit use 3
Critical PPI prescribing details:
- PPIs must be taken 30-60 minutes before meals for optimal effect 3
- H2-receptor antagonists develop tolerance within 6 weeks, limiting long-term effectiveness 3
- If symptoms persist despite optimized PPI therapy (twice daily for 8 weeks), endoscopy is indicated 3
Long-Term Management
After initial symptom resolution, attempt treatment withdrawal to assess if ongoing therapy is needed. 2
If symptoms recur, restart the successful medication and consider on-demand therapy (taking PPI only when symptoms occur) to minimize long-term exposure. 2, 5
Taper to the lowest effective dose rather than continuing full-dose indefinitely. 2
When to Refer to Gastroenterology
Refer when diagnostic doubt exists, symptoms are severe or refractory to first-line treatments (H. pylori eradication and 8 weeks of optimized PPI therapy), or the patient requests specialist opinion. 1, 2
Ideally, patients should be managed in a specialist clinic with access to dietetic support and gut-brain behavioral therapies. 1
Lifestyle Modifications
Advise all patients to take regular aerobic exercise. 1, 2
There is insufficient evidence to recommend specific dietary therapies, including low-FODMAP diets, for functional dyspepsia. 1, 2
Common Pitfalls to Avoid
- Do not use whole blood H. pylori tests—they lack adequate sensitivity and specificity for reliable test-and-treat strategies 1
- Do not use H2-receptor antagonists as first-line therapy—they are significantly less effective than PPIs and develop tolerance within 6 weeks 3, 4
- Do not forget to take PPIs 30-60 minutes before meals—timing is critical for optimal acid suppression 3
- Do not continue NSAIDs in patients with peptic ulcer disease—they significantly increase recurrence and complication risk 4
- Do not assume H. pylori eradication will resolve all symptoms—many patients require subsequent acid suppression therapy 1, 3
