Gastric Ulcer: Causes, Symptoms, and Visual Comparison #3398562 (License: Personal Use)

The image displays two cross-sectional views of the human stomach: the left shows a healthy gastric mucosa with smooth, intact lining, while the right reveals multiple dark, crater-like ulcers penetrating the stomach wall. These ulcers result from erosion of the protective mucosal barrier, often due to H. pylori infection or NSAID overuse. The visual contrast highlights the structural damage associated with chronic gastritis and peptic ulcer disease.

Used in gastroenterology educational content, patient brochures, or health websites explaining peptic ulcer disease; targets users searching for symptoms, diagnosis, or visual anatomy of stomach ulcers.
