For Patients & General Readers

Peptic ulcer disease (PUD) is a common condition where sores, called ulcers, form in the lining of your stomach or the first part of your small intestine. It often affects adults and can cause significant discomfort if left untreated, potentially leading to serious complications.

Clinical Overview

Peptic ulcer disease (PUD) is characterized by a break in the gastric or duodenal mucosa, typically caused by an imbalance between aggressive factors (e.g., H. pylori infection, NSAID use) and protective mechanisms. It presents with epigastric pain and can lead to complications such as bleeding, perforation, and obstruction.

Clinical Presentation

Epigastric pain, often described as burning, gnawing, or aching.
Pain that may be relieved by food or antacids (duodenal ulcers) or worsened by food (gastric ulcers).
Nausea and vomiting.
Bloating and early satiety.
Unexplained weight loss.
Hematemesis (vomiting blood) or melena (black, tarry stools) in cases of bleeding.

Signs & Symptoms

Symptoms (Patient-Reported)

Burning or gnawing pain in the upper abdomen
Pain that gets better after eating or taking antacids
Pain that returns after a few hours
Feeling full quickly
Bloating
Heartburn
Nausea

Signs (Clinician-Observed)

Epigastric tenderness on palpation
Signs of anemia (pallor, tachycardia) in cases of chronic blood loss
Vomiting of blood (hematemesis) or passage of black, tarry stools (melena)
Abdominal distension and rigidity in cases of perforation

Differential Diagnoses

Condition	Distinguishing Feature
Gastritis	Inflammation of the stomach lining, often without a discrete ulcer lesion. Pain may be less localized and more diffuse.
Gastroesophageal Reflux Disease (GERD)	Characterized by heartburn and regurgitation, typically without the deep mucosal erosion seen in PUD. Pain is often retrosternal.
Functional Dyspepsia	Chronic or recurrent indigestion without evidence of organic disease on endoscopy. Symptoms may overlap but lack objective findings of ulceration.
Pancreatitis	Inflammation of the pancreas, often causing severe epigastric pain radiating to the back, accompanied by nausea, vomiting, and elevated pancreatic enzymes.
Biliary Colic	Intermittent, severe right upper quadrant or epigastric pain, often postprandial, associated with gallstones. Pain may radiate to the shoulder.
Malignancy (Gastric Cancer)	Can present with similar symptoms but often associated with progressive weight loss, early satiety, and a palpable mass. Endoscopy with biopsy is crucial for diagnosis.

Red Flags — Seek Immediate Care

Hematemesis or melena (signs of active bleeding)
Severe, intractable abdominal pain, especially with rigidity (suggestive of perforation)
Unexplained weight loss
Difficulty swallowing (dysphagia) or persistent vomiting (suggestive of obstruction)

Key Investigations

Upper endoscopy (esophagogastroduodenoscopy - EGD) with biopsies for histology and H. pylori testing.
Urea breath test, stool antigen test, or serology for Helicobacter pylori infection.
Complete blood count (CBC) to assess for anemia.
Fecal occult blood test (FOBT) if endoscopy is not immediately available and bleeding is suspected.

Management Overview

Management focuses on eradicating H. pylori infection (if present) with antibiotics and acid suppression therapy (e.g., proton pump inhibitors - PPIs) and discontinuing offending agents like NSAIDs. For bleeding ulcers, endoscopic hemostasis and aggressive acid suppression are indicated. Recurrence can be prevented with continued H. pylori eradication and judicious use of acid-suppressing medications.
