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.
