Peptic Ulcer (Stomach Ulcer)

A peptic ulcer is a sore in the lining of your stomach or upper small intestine. Ulcers form when the protective layer in the lining has broken down, often because of a bacterial infection or frequent use of aspirin or similar medicine.

Peptic ulcers can cause pain in the belly, above the belly button. Ulcers can also bleed.
