Disease category
Peptic ulcer disease refers to an ulcer that has formed in the gastric or duodenal mucosa.
Core mechanism
Major related factors are Helicobacter pylori infection and long-term use of NSAIDs such as aspirin and ibuprofen.
Main causes · related factors
Ulcers can form when damage from gastric acid and digestive processes exceeds mucosal defenses.
Representative manifestations
A representative pattern is epigastric burning or gnawing pain that appears between meals or at night.
Individual variation
Symptoms and the risk of complications may vary depending on the cause, the location and size of the ulcer, comorbidities, and medications being taken.
Diagnosis
Pain may last for minutes to hours or recur for days to weeks, and the clinical course differs if accompanied by bleeding, perforation, or obstruction.
Management
Diagnosis is performed based on medical history and medication verification, combining H. pylori testing, upper gastrointestinal endoscopy, or necessary imaging studies.
Treatment/Research Status
H. pylori test results and endoscopic findings must be interpreted along with the timing of the test, recent medications, and whether a biopsy was performed; a single test alone cannot confirm all causes.
Read Evidence
The key to management is correcting the cause, suppressing gastric acid, evaluating symptoms and complications, and controlling exacerbating factors such as smoking and alcohol consumption.
Key Precautions
Treatment involves using medications to reduce gastric acid, and if H. pylori is confirmed, antibiotic therapy for eradication should be considered.

At a Glance

Peptic ulcer disease refers to an ulcer that has formed in the gastric or duodenal mucosa.

A representative pattern is epigastric burning or gnawing pain that appears between meals or at night.

How the disease works

Major related factors are Helicobacter pylori infection and long-term use of NSAIDs such as aspirin and ibuprofen.

Ulcers can form when damage from gastric acid and digestive processes exceeds mucosal defenses.

Variations in presentation among individuals

Symptoms and the risk of complications may vary depending on the cause, the location and size of the ulcer, comorbidities, and medications being taken.

The broad framework of diagnosis and management

Pain may last for minutes to hours or recur for days to weeks, and the clinical course differs if accompanied by bleeding, perforation, or obstruction.

Diagnosis is performed based on medical history and medication verification, combining H. pylori testing, upper gastrointestinal endoscopy, or necessary imaging studies.

Current status of treatment

H. pylori test results and endoscopic findings must be interpreted along with the timing of the test, recent medications, and whether a biopsy was performed; a single test alone cannot confirm all causes.

The key to management is correcting the cause, suppressing gastric acid, evaluating symptoms and complications, and controlling exacerbating factors such as smoking and alcohol consumption.

Treatment involves using medications to reduce gastric acid, and if H. pylori is confirmed, antibiotic therapy for eradication should be considered.

How to read clinical trials

Clinical trial registration only indicates the existence and design of the study; it does not demonstrate efficacy, safety, approval, or status as standard treatment, so results must be interpreted separately from the reporting.

Points to verify during clinical consultations

In clinical practice, pain patterns, signs of bleeding, H. pylori testing/treatment history, medications including NSAIDs, smoking/alcohol consumption, and recurrence status can be confirmed.
