Question

What is the most common site of a chronic gastric ulcer?

• A. Pyloric antrum
• B. Upper part of lesser curvature
• C. Lower part of lesser curvature
• D. Segment of large intestine

Hint:

Where does H. pylori preferentially colonise the stomach?

Answer 1

The Correct Option is A

Step 1: Chronic gastric ulcers form where the mucosal barrier is most often breached. A major cause (about 60% of gastric and up to 50-75% of duodenal ulcers) is chronic inflammation from Helicobacter pylori, which preferentially colonises the antral mucosa.
Step 2: Because the pyloric antrum bears the brunt of H. pylori colonisation and acid-related injury, it is the most common site of a chronic gastric ulcer, making option (a) correct.
Step 3: The lesser curvature is a recognised site but ranks below the antrum, and the large intestine (option d) is not where a gastric ulcer occurs at all. The answer is option (a), Pyloric antrum.
