Stomach ulcers are the most visible sign of peptic ulcer disease. They occur when the thick layer of mucus that protects your stomach from digestive juices is reduced, thus enabling the digestive acids to eat away at the lining tissues of the stomach.
The most common symptom of peptic ulcers is abdominal pain. 1  The pain is usually in the upper middle part of the abdomen, above the belly button (navel) and below the breastbone. 2  The ulcer pain can feel like burning, or gnawing, and it may go through to the back. 3  Pain often comes several hours after a meal when the stomach is empty.
