**Question:** Most common complication of gastric ulcer -

A. Gastric Cancer
B. Gastric Perforation
C. Gastric Stenosis
D. Gastric Variceal Bleeding

**Core Concept:**
Gastric ulcers are lesions that occur in the gastric mucosa due to various factors like H. pylori infection, nonsteroidal anti-inflammatory drug (NSAID) use, or genetic predisposition. They commonly develop into complications depending on the severity and duration of the ulcer. The most common complications arise from the ulcer's direct involvement or secondary to its effects on the surrounding tissues and blood vessels.

**Why the Correct Answer is Right:**
The correct answer is D (Gastric Variceal Bleeding) because gastric ulcers can lead to gastrointestinal bleeding due to the weakening of the mucosa and blood vessels in the affected area. Gastric varices are dilated portal venules that can rupture, causing life-threatening gastrointestinal bleeding. This complication is more likely than gastric cancer (A) as it arises directly from the ulcer's effects on blood vessels, whereas gastric cancer is a separate entity with distinct risk factors and presentation.

**Why Each Wrong Option is Incorrect:**
A. Gastric Cancer (A): Although gastric cancer can occur as a complication of untreated H. pylori infection or NSAID use, it is not the most common complication of gastric ulcers. Gastric cancer is a separate entity with distinct risk factors, symptoms, and imaging findings.

B. Gastric Perforation: Although gastric ulcers can perforate, the correct answer (D) is more common due to the direct involvement of blood vessels by the ulcer. Perforation is a separate complication that occurs due to the ulcer's direct penetration of the gastric wall, whereas D focuses on the indirect effects of the ulcer.

C. Gastric Stenosis: Gastric ulcers can cause stenosis by narrowing the lumen, leading to obstructive symptoms like dyspepsia, vomiting, and weight loss. However, this complication is less common than gastric variceal bleeding (D).

**Clinical Pearl:**
Gastric ulcers should be managed promptly to prevent complications. H. pylori eradication, proton pump inhibitors, and H2-receptor antagonists are the cornerstones of ulcer management. Early detection and treatment can prevent complications like gastric variceal bleeding, gastric perforation, and gastric stenosis.

**Explanation:**

Gastric ulcers are common lesions in the stomach lining that can be caused by various factors, including H. pylori infection, NSAID use, and genetic predisposition. These ulcers can lead to several complications, depending on the ulcer's location, size, and severity.

The most common complication is gastric variceal bleeding (D), which arises due to the ulcer's indirect effects on blood vessels within the stomach wall. Blood vessel damage can lead to the formation of varices, which are dilated blood vessels and can rupture, causing life-threatening gastrointestinal bleeding.
