A gastric ulcer is a distinct manifestation of peptic ulcer disease characterized by a mucosal break in the stomach wall that penetrates through the muscularis mucosae It develops within the gastrointestinal tract—predominantly affecting adults—when protective mucosal defenses such as prostaglandin synthesis, mucus secretion, and microvascular blood flow are disrupted by aggressive factors like luminal gastric acid and pepsin

Pathophysiologically, the most frequent etiologies are *Helicobacter pylori* infection and the regular use of nonsteroidal anti-inflammatory drugs Patients commonly present with epigastric pain, postprandial dyspepsia, nausea, or early satiety, with severe forms risking complications such as upper gastrointestinal hemorrhage, perforation, or gastric outlet obstruction
