Since H. pylori infection is a major cause of PUD, it’s usually checked via:
Urea breath test (non-invasive, very accurate)
Stool antigen test
Serology (less useful now due to inability to distinguish past vs. active infection)
Biopsy with histology, urease testing, or culture (done during endoscopy)
This is the gold standard for diagnosing PUD:
Directly visualizes ulcers in the stomach or duodenum
Allows for biopsy to rule out malignancy (especially for gastric ulcers)
Can test for H. pylori
Used especially when:
Symptoms are severe or persistent
There are alarm features
The patient is older (usually >60) or has risk factors for gastric cancer
Upper GI series with barium swallow can be used if endoscopy is not available, though it is less sensitive and specific.
Occasionally used to detect complications like perforation, penetration, or obstruction.
✅ Initial step: assess symptoms and test for H. pylori
✅ Best diagnostic tool: upper endoscopy
✅ Look for complications: with imaging if needed
Let me know if you want the diagnostic steps based on age, risk factors, or whether you’re approaching this from a primary care or specialist perspective.++++++++++++++++
Yes, endoscopy is indicated in the diagnosis of peptic ulcer disease (PUD), but whether it's done right away depends on the patient's age, symptoms, and risk factors.
Upper endoscopy (EGD) is recommended as the first-line diagnostic test in patients who have:
Alarm symptoms, such as:
Gastrointestinal bleeding (melena, hematemesis)
Unexplained weight loss
Persistent vomiting
Iron-deficiency anemia
Dysphagia or odynophagia
Age ≥ 60 years (some guidelines use ≥ 55 years) with new-onset dyspepsia
Failure of initial treatment or recurrent symptoms despite therapy
High risk for gastric cancer, such as:
Family history of gastric cancer
History of gastric surgery
Immigrants from high-risk regions (e.g., East Asia)
In younger patients (<60 years) without alarm symptoms, initial management can focus on:
Non-invasive testing for H. pylori (urea breath test or stool antigen)
Empiric treatment with proton pump inhibitors (PPIs)
Endoscopy is reserved for those who:
Don’t respond to therapy
Have recurrent symptoms
Develop alarm features later
Direct visualization of ulcers
Ability to biopsy gastric ulcers (to rule out cancer)
Testing for H. pylori via biopsy
Assess for complications (e.g., bleeding, obstruction)
Yes, endoscopy is definitive for diagnosing PUD.
Indicated early if patient is older or has alarm features.
Can be delayed in younger, low-risk patients after empiric therapy and non-invasive H. pylori testing.

A stool antigen test is positive for Helicobacter pylori, and the patient is treated for peptic ulcer disease with eradication therapy.
