Exam Tips

  • In OSCEs, state that proven peptic ulcer requires endoscopic confirmation and that gastric ulcers need malignancy exclusion strategy.
  • Memorize H. pylori test preparation: stop PPI for 2 weeks and antibiotics for 4 weeks before breath or stool antigen testing.
  • Quote core eradication doses: amoxicillin 1 g BD, clarithromycin 500 mg BD, metronidazole 400 mg BD, with a PPI BD for 7 days.
  • Differentiate patterns: duodenal ulcers classically improve with food then recur; gastric ulcers may worsen with eating and can cause weight loss.
  • Always mention red flags/complications (bleeding, perforation, obstruction, cancer features) and need for urgent referral when present.

Definition

Proven peptic ulcer dyspepsia is upper gastrointestinal symptomatology (typically at least 4 weeks of epigastric pain/discomfort, with possible nausea, heartburn, or reflux) in which endoscopy confirms a gastric or duodenal mucosal break extending through the muscularis mucosae. It is a structural cause of dyspepsia, most commonly linked to Helicobacter pylori infection and/or ulcerogenic drugs such as NSAIDs.

Pathophysiology

Peptic ulcers arise when mucosal defence (mucus-bicarbonate barrier, epithelial restitution, blood flow, prostaglandin-mediated protection) is overwhelmed by acid-peptic injury. H. pylori drives chronic active gastritis; antral-predominant infection can increase gastrin and acid output (classically predisposing to duodenal ulcer), whereas corpus-predominant atrophic change can reduce acid yet impair mucosal integrity and increase gastric ulcer and malignancy risk. NSAIDs and aspirin inhibit COX-mediated prostaglandin synthesis, reducing mucosal protection and increasing bleeding risk; combined NSAID use plus H. pylori further amplifies ulcer risk. See Figure from standard GI pathology texts showing acid-peptic injury versus mucosal defence balance and typical endoscopic ulcer crater appearances.

Risk Factors

  • Helicobacter pylori infection (very common in duodenal ulcer and frequent in gastric ulcer)
  • Current or recent NSAID use, including chronic non-prescription use
  • Aspirin (including low-dose antiplatelet therapy)
  • Other ulcerogenic drugs: corticosteroids, SSRIs, bisphosphonates, potassium supplements
  • Smoking (current or former)
  • Older age and significant comorbidity (also increases complication risk)
  • Anticoagulant use (raises risk of severe bleeding if ulcer occurs)
  • Possible contributors: excess alcohol and psychological stress (association less consistent)
  • Rare hypersecretory states such as Zollinger-Ellison syndrome

Clinical Features

Symptoms

  • Epigastric pain or burning discomfort
  • Postprandial dyspepsia, bloating, early satiety, nausea, occasional vomiting
  • Nocturnal epigastric pain (more typical of duodenal ulcer pattern)
  • Upper GI bleeding symptoms: melaena, haematemesis, fatigue/dizziness from iron deficiency or acute blood loss
  • Features of complications: sudden severe generalized abdominal pain (perforation), persistent vomiting and early satiety (gastric outlet obstruction), unintentional weight loss

Signs

  • Epigastric tenderness (often mild or absent between flares)
  • Pallor or tachycardia in chronic/acute bleeding
  • Hypotension or shock in major haemorrhage
  • Peritonism/rigid abdomen in perforation
  • Visible dehydration or succussion splash in gastric outlet obstruction

Investigations

Upper GI endoscopy (OGD):Confirms gastric or duodenal ulcer crater; enables biopsy of gastric ulcers to exclude malignancy and assess healing where indicated.
H. pylori testing (13C urea breath test or stool antigen):Positive test supports infective aetiology; ensure no PPI for 2 weeks and no antibiotics for 4 weeks pre-test to reduce false negatives.
FBC and ferritin:Iron deficiency anaemia or acute blood loss pattern in bleeding ulcer.
Urea, creatinine, electrolytes:Assesses dehydration/renal impact, especially in vomiting, bleeding, or older patients.
Liver profile, amylase/lipase if diagnostic uncertainty:Helps exclude hepatobiliary or pancreatic causes in dyspeptic/epigastric pain presentations.

Management

Lifestyle Modifications

  • Stop smoking and reduce alcohol to UK recommended limits
  • Weight reduction if overweight, and avoid personal trigger foods (for example fatty/spicy meals, coffee, chocolate, tomato-based foods)
  • Smaller meals and avoid late evening meals (aim 3-4 hours before sleep)
  • Address stress, anxiety, and depression; consider psychological support if symptoms are amplified by psychosocial factors
  • Provide safety-netting: urgent assessment for haematemesis, melaena, syncope, severe sudden abdominal pain, persistent vomiting, dysphagia, or weight loss

Pharmacological Treatment

Acid suppression for ulcer healing (PPI)

  • Lansoprazole 30 mg once daily
  • Omeprazole 20-40 mg once daily
  • Esomeprazole 20 mg once daily
  • Pantoprazole 40 mg once daily
  • Rabeprazole 20 mg once daily

Use full-dose PPI for 4-8 weeks (often 4 weeks duodenal, 8 weeks gastric). If NSAID-associated and H. pylori positive, give full-dose PPI for about 2 months before eradication therapy. Long-term PPI risks include C. difficile infection, hypomagnesaemia, fractures, and rebound acid symptoms on abrupt withdrawal; review ongoing need.

First-line H. pylori eradication (7-day triple therapy)

  • PPI twice daily + amoxicillin 1 g twice daily + clarithromycin 500 mg twice daily
  • PPI twice daily + amoxicillin 1 g twice daily + metronidazole 400 mg twice daily
  • If penicillin allergy: PPI twice daily + clarithromycin 500 mg twice daily + metronidazole 400 mg twice daily

Choose regimen with antimicrobial stewardship in mind, considering prior macrolide/metronidazole exposure. Emphasize strict adherence. Clarithromycin: QT-prolongation/drug-interaction risk (including statins and some antiarrhythmics). Metronidazole: avoid alcohol during treatment and for at least 48 hours after. Amoxicillin contraindicated in true penicillin allergy.

Medication review and gastroprotection

  • Stop NSAID if possible
  • If anti-inflammatory therapy cannot be stopped, co-prescribe a PPI
  • Review need for aspirin, corticosteroids, SSRIs, bisphosphonates, and potassium supplements

Balance thrombotic versus bleeding risk before stopping antiplatelets/anticoagulants; involve relevant specialty if high cardiovascular risk. Avoid prolonged unsupervised antacid/alginates; short-term rescue use is acceptable.

Surgical / Interventional

  • Urgent endoscopic haemostasis for bleeding ulcer (for example adrenaline injection with thermal/mechanical therapy)
  • Laparoscopic or open repair for perforated ulcer (for example omental patch repair) with broad resuscitative management
  • Endoscopic balloon dilatation or surgery for persistent gastric outlet obstruction from chronic scarring/stenosis

Complications

  • Upper GI haemorrhage (acute life-threatening bleed or chronic occult blood loss causing iron deficiency anaemia)
  • Perforation with peritonitis and sepsis
  • Gastric outlet obstruction due to pyloric/duodenal inflammation and fibrosis
  • Ulcer recurrence, especially if H. pylori persists or NSAID exposure continues
  • Increased risk of gastric malignancy in H. pylori-associated gastric ulcer disease

Prognosis

With appropriate PPI therapy, duodenal ulcers usually heal within about 4 weeks and gastric ulcers within about 8 weeks. Eradication of H. pylori markedly lowers lifetime recurrence risk (from around 60% to 5% for gastric ulcer and from around 80% to 5% for duodenal ulcer). Prognosis worsens with older age, comorbidity, NSAID/anticoagulant exposure, and complications: bleeding and perforation still carry substantial mortality in UK practice, particularly in older adults.
