How Can an Ulcer Form Inside Your Stomach?

READ THE IMAGE

What the illustration shows

Gold-titled poster asks how an ulcer can form inside the stomach. A small opened-stomach view locates a sore. A dominant layered wall section shows a central crater crossing the lining and its thin basal muscle into shallow submucosa; deeper muscle and the outer wall remain intact. Blue stomach contents lie above a thin pale mucus coat on adjacent intact lining. Leaders identify digestive acid, mucus, mucosa, muscularis mucosae, submucosa and deeper muscle. Two lower panels name H. pylori infection and NSAIDs as common causes that can weaken protection, with a note that neither causes an ulcer in everyone. A qualifier says the image is not a diagnosis or advice to change medicines. Gold AllHumanBody.com branding and the full slogan appear below. The anatomy is illustrative and not to scale.

How to interpret this poster

• Simplified mucus depiction does not exhaust protective mechanisms. Not a perforation, symptom diagnosis or advice to start/stop/change medicines.
• AI-assisted educational illustration; not physician certification, a diagnosis or individualized medical advice.
• Fine annotations require enlargement; preserve the full uncropped illustration and its qualifiers.
