When to refer a patient with dyspepsia to a gastroenterologist (GI) specialist?

When to Refer to Gastroenterology for Dyspepsia

Patients with dyspepsia should be referred to gastroenterology when there is diagnostic doubt, severe symptoms, symptoms refractory to first-line treatments, or when the patient specifically requests specialist consultation. 1

Initial Management Before Referral

Immediate Endoscopy Indications (Alarm Features)

• Age ≥55 years with weight loss 1
• Age >40 years from high-risk gastric cancer areas or with family history of gastro-esophageal cancer 1
• Age ≥55 years with treatment-resistant dyspepsia 1
• Age ≥55 years with raised platelet count, nausea, or vomiting 1
• Age ≥60 years with abdominal pain and weight loss (consider urgent abdominal CT to exclude pancreatic cancer) 1
• Other alarm features: recurrent vomiting, dysphagia, bleeding/anemia, jaundice, or palpable mass 2

First-Line Management Algorithm

1. Test for H. pylori using validated non-invasive test in patients without alarm features 1, 2

   • If positive → Provide eradication therapy
   • If negative → Proceed to acid suppression therapy

2. Acid Suppression Trial

   • Proton pump inhibitor (PPI) at lowest effective dose for 4-8 weeks 1, 2
   • Consider histamine receptor antagonists as alternative 1

3. Lifestyle Modifications

   • Regular aerobic exercise (strongly recommended) 1, 2
   • Avoid overly restrictive diets 2

Specific Referral Criteria

Definite Referral Indications

1. Diagnostic uncertainty after initial workup 1
2. Severe symptoms impacting quality of life despite first-line treatments 1
3. Refractory symptoms after:
   • Failed H. pylori test-and-treat strategy
   • Failed 4-8 week trial of PPI therapy
   • Failed trial of alternative medication (different PPI, H2 blocker, or prokinetic) 1, 2
4. Patient request for specialist opinion 1

Additional Considerations for Referral

• Patients with overlapping IBS symptoms who test positive for celiac disease 1
• Patients requiring second-line treatments like tricyclic antidepressants who don't respond or have significant side effects 1, 2
• Need for specialized testing not available in primary care 1

What to Expect After Referral

Patients referred to gastroenterology for functional dyspepsia should ideally be managed in a specialist clinic with:

• Access to an interested gastroenterologist
• Dietetic and lifestyle support
• Access to efficacious medications
• Access to gut-brain behavioral therapies 1

Common Pitfalls to Avoid

• Overuse of endoscopy in young patients without alarm features 2
• Inadequate patient education about H. pylori eradication and realistic expectations 2
• Inappropriate use of opioids in patients with severe or refractory symptoms 2
• Neglecting psychological factors in patients with persistent symptoms 2
• Routine ordering of gastric emptying testing or 24-hour pH monitoring in typical functional dyspepsia (not recommended) 1

By following this algorithm, primary care providers can appropriately manage dyspepsia and refer to gastroenterology when necessary, optimizing patient outcomes while using healthcare resources efficiently.
