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 first symptom of peptic ulcer is usually stomach pain, caused by the ulcer and intensified by stomach acid coming in contact with it. However, it is not uncommon for people to have a peptic ulcer and no symptoms at all. One of the most common symptoms of peptic ulcers is indigestion-like pain.
