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.
There may be no symptoms of ulcers or the individual may experience: 1  A gnawing or burning pain in the abdomen between the breastbone and the navel. The pain is usually worse a couple of hours after a meal or in the middle of the night when the stomach is empty. 2  Nausea. 3  Vomiting. 4  Loss of appetite. 5  Loss of weight.
