What is the initial management for a patient presenting with epigastric fullness?

Initial Management of Epigastric Fullness

The initial management of epigastric fullness requires immediate exclusion of alarm features followed by H. pylori testing and empirical acid suppression therapy, with endoscopy reserved for patients ≥55 years or those with red flag symptoms. 1

Immediate Risk Stratification

Screen for alarm features that mandate urgent investigation:

• Weight loss in patients ≥55 years requires 2-week wait endoscopy 1
• Dysphagia suggests esophageal pathology requiring urgent evaluation 2
• Persistent vomiting excludes functional dyspepsia and mandates investigation for structural disease 3, 4
• Hematemesis suggests bleeding ulcer or malignancy 2
• Anemia on complete blood count warrants urgent endoscopy 4
• Family history of gastro-oesophageal malignancy in patients >40 years requires 2-week wait endoscopy 1

Critical pitfall: Never dismiss cardiac causes—obtain an ECG to exclude myocardial infarction, which can present atypically with epigastric symptoms, particularly in women, diabetics, and elderly patients with mortality rates of 10-20% if missed. 3, 4

Baseline Investigations for All Patients

Order the following tests before initiating empirical therapy:

• Full blood count in patients aged ≥55 years to detect anemia 1
• H. pylori testing via breath or stool testing (not serology) for all patients with epigastric fullness 1, 3
• Coeliac serology if overlap with IBS-type symptoms is present 1

Age-Based Management Algorithm

Patients <55 Years Without Alarm Features

Proceed directly to "test and treat" strategy:

• If H. pylori positive: Initiate triple therapy with omeprazole 20 mg + amoxicillin 1000 mg + clarithromycin 500 mg, all twice daily for 10 days 3
• Network meta-analysis demonstrates this approach ranks first in reducing symptoms at 12 months (RR 0.89; 95% CI 0.78-1.0) 3
• If H. pylori negative or symptoms persist after eradication: Start omeprazole 20 mg once daily before meals for 4-8 weeks 3
• Healing rates are 80-90% for duodenal ulcers and 70-80% for gastric ulcers 3

Patients ≥55 Years

Endoscopy thresholds are lower in this age group:

• 2-week wait endoscopy if weight loss is present 1
• Non-urgent endoscopy for treatment-resistant dyspepsia or raised platelet count 1, 4
• While awaiting endoscopy, initiate H. pylori testing and empirical PPI therapy 3

Symptom-Specific Considerations

Epigastric fullness specifically suggests postprandial distress syndrome:

• This presentation is characterized by early satiety, bloating, and discomfort worse after eating 1, 5
• After PPI trial failure: Consider prokinetic agents, though options are limited due to safety concerns 3
• Symptoms typically worsen with solid foods more than liquids 5

Important distinction: Pain unrelated to defecation favors functional dyspepsia over IBS, while burning sensation radiating to chest suggests GERD rather than functional dyspepsia. 3

Additional Investigations to Consider

Based on clinical presentation:

• Abdominal ultrasound if epigastric pain <1 year with characteristics of biliary colic 1
• Urgent CT scan if abdominal pain with weight loss in patients ≥60 years 1
• CT abdomen with IV contrast is the gold standard when diagnosis is unclear, identifying complications like perforation (showing extraluminal gas in 97% of cases) 3, 4

Patient Education and Engagement

Establish a positive diagnosis of functional dyspepsia after normal investigations:

• Explain the condition in the context of the gut-brain axis 1
• Discuss common symptom triggers including diet, stress, and postinfective changes 1
• Emphasize that normal test results do not mean there is no cause—functional dyspepsia results from issues with two-way communication between the upper gut and brain 1
• An effective and empathic doctor-patient relationship may reduce healthcare utilization and improve quality of life 1

Critical Pitfalls to Avoid

• Do not use H. pylori serology for test-and-treat strategy—use breath or stool testing only, as serology has lower specificity 3
• Do not delay endoscopy in patients with alarm features, as missing gastric cancer or perforated ulcer leads to poor outcomes 3, 4
• Avoid NSAIDs, which worsen peptic ulcer disease and are associated with dyspepsia in multiple population-based studies 3
• Do not attribute persistent vomiting to functional dyspepsia—Rome IV criteria state this suggests another disorder and mandates investigation for structural disease 3, 4
• The yield of endoscopy for detecting cancer in unselected dyspepsia patients is <0.5%, but rises significantly with alarm features present 1
