Dyspepsia - proven GORD
💡
Exam Tips
- In UK exams, distinguish 'proven GORD' from uninvestigated dyspepsia: proven disease has prior endoscopic classification and is treated with full-dose PPI for healing.
- Severe oesophagitis usually needs 8-week full-dose PPI and often long-term maintenance; non-severe proven GORD usually starts with 4 weeks.
- Do not routinely request H. pylori testing when proven GORD is already established endoscopically.
- Always screen for alarm features and cancer risk triggers before routine reflux management.
- Know Barrett's pathway conceptually: chronic reflux -> intestinal metaplasia -> increased adenocarcinoma risk; this underpins surveillance discussions.
- For visual memory, review a standard textbook diagram of the anti-reflux barrier (lower oesophageal sphincter plus diaphragmatic crura) and an endoscopic image set of Los Angeles oesophagitis grades.
Definition
Proven gastro-oesophageal reflux disease (GORD) is dyspepsia predominantly caused by reflux of gastric contents into the oesophagus, confirmed by prior endoscopic assessment (erosive oesophagitis or endoscopy-negative reflux disease with typical reflux symptoms). It usually presents as a chronic relapsing syndrome of heartburn and acid regurgitation lasting at least 4 weeks, and may also produce extra-oesophageal symptoms such as cough, hoarseness, or dental enamel erosion.
Pathophysiology
GORD results from failure of the anti-reflux barrier at the gastro-oesophageal junction. Key mechanisms include transient lower oesophageal sphincter relaxations, reduced resting sphincter tone, increased intra-gastric pressure (for example obesity, straining, coughing), delayed gastric emptying, and impaired oesophageal acid clearance (reduced peristalsis/saliva buffering). Refluxate (acid, pepsin, sometimes bile) causes mucosal inflammation and erosions in erosive disease; repeated injury-repair can lead to fibrosis (stricture) or intestinal metaplasia (Barrett's oesophagus).
Risk Factors
- Obesity
- Smoking
- Alcohol excess
- Trigger foods (for some patients): coffee, chocolate, fatty meals, spicy foods, tomatoes
- Pregnancy
- Hiatus hernia
- Stress and anxiety
- Family history/genetic susceptibility
- Medicines that reduce LOS tone or irritate oesophagus: nitrates, calcium-channel blockers, anticholinergics, benzodiazepines, beta-blockers, tricyclic antidepressants, theophyllines, alpha-blockers, bisphosphonates, corticosteroids, NSAIDs
Clinical Features
Symptoms
- Heartburn (retrosternal burning, often post-prandial)
- Acid regurgitation/sour taste
- Upper abdominal or retrosternal discomfort
- Symptoms worse after large meals, bending, lying flat, or late-night eating
- Nausea (occasionally vomiting)
- Atypical symptoms: chronic cough, hoarseness, throat clearing, wheeze/asthma exacerbation, dental sensitivity from enamel loss
- Alarm features needing urgent assessment: progressive dysphagia, odynophagia, GI bleeding, weight loss, persistent vomiting, iron-deficiency anaemia
Signs
- Often no abnormal abdominal findings on examination
- Epigastric tenderness may be mild and non-specific
- Dental erosions/halitosis in chronic reflux
- Features of complications: pallor (chronic blood loss), signs of aspiration-related chest infection, evidence of dehydration if persistent vomiting
Investigations
Upper GI endoscopy (already establishes 'proven GORD'):Erosive oesophagitis/ulceration/stricture/Barrett's change, or normal mucosa in endoscopy-negative reflux disease
Full blood count:May show iron-deficiency anaemia if chronic oesophageal blood loss
Ambulatory oesophageal pH-impedance monitoring (if refractory/diagnostic uncertainty):Pathological acid exposure and/or symptom-reflux association
Oesophageal manometry (pre-operative or alternative diagnosis work-up):Assesses motility disorder; helps exclude achalasia before anti-reflux surgery
Management
Lifestyle Modifications
- Weight reduction if overweight/obese
- Stop smoking and reduce alcohol intake to recommended UK limits
- Identify and reduce individual dietary triggers (commonly fatty foods, chocolate, coffee, spicy foods, tomatoes)
- Smaller meals; avoid eating for 3-4 hours before bed
- Raise head end of bed by about 10-20 cm (bed blocks/wedge, not extra pillows)
- Review stress/anxiety contributors and support behavioural strategies
- Medication review to reduce/stop exacerbating drugs where clinically appropriate
Pharmacological Treatment
Proton pump inhibitors (first-line healing therapy)
- Omeprazole 20 mg once daily for 4 weeks (8 weeks if severe oesophagitis)
- Lansoprazole 30 mg once daily for 4 weeks (8 weeks if severe oesophagitis)
- Pantoprazole 40 mg once daily for 4 weeks (8 weeks if severe oesophagitis)
- Esomeprazole 40 mg once daily for 4 weeks (8 weeks if severe oesophagitis)
- Rabeprazole 20 mg once daily for 4 weeks (8 weeks if severe oesophagitis)
For proven severe erosive oesophagitis, continue long-term maintenance PPI (often full dose initially, then lowest effective dose if possible). For proven GORD, routine H. pylori testing is not indicated. Safety: review long-term PPI need periodically; risks include C. difficile infection, hypomagnesaemia, B12 deficiency, fracture risk, and rare acute interstitial nephritis. Interaction caution: avoid omeprazole/esomeprazole with clopidogrel when possible (consider lansoprazole or pantoprazole).
Alginates/antacids (adjunct symptom relief)
- Sodium alginate compound (for example Gaviscon Advance) 5-10 mL after meals and at bedtime, as required
- Simple antacid preparations as needed between PPI doses
Useful for breakthrough symptoms or regurgitation. Check sodium load in patients with heart failure, severe renal disease, or sodium-restricted diets.
Surgical / Interventional
- Laparoscopic fundoplication (for objectively confirmed reflux with persistent symptoms/regurgitation despite optimized medical therapy, or where long-term medication is unsuitable)
- Hiatus hernia repair when anatomically significant and clinically contributory
Complications
- Erosive oesophagitis
- Oesophageal ulceration and haemorrhage
- Chronic iron-deficiency anaemia from occult blood loss
- Peptic oesophageal stricture causing progressive dysphagia
- Aspiration pneumonitis/pneumonia
- Barrett's oesophagus with increased risk of oesophageal adenocarcinoma
- Oral complications: dental erosions, gingivitis, halitosis
Prognosis
GORD is typically chronic and relapsing: untreated recurrence is common (about half recur within 1 year, with high lifetime relapse). Even after good initial response, many patients relapse without maintenance therapy, particularly those with severe oesophagitis. A minority progress to complications such as stricture or Barrett's oesophagus; malignant progression risk is concentrated in Barrett's metaplasia.
