The acid in peptic ulcers can damage stomach tissue.
Explanation:
Ulcers form when the intestine or stomach's protective layer is broken down. When this happens, digestive juices - which contain hydrochloric acid an anzyme called pepsin - can damage the intestine or stomach tissue.
Peptic ulcer disease occurs when open sores, or ulcers, form in the stomach or first part of the small intestine. Many cases of peptic ulcer disease develop because a bacterial infection eats away the protective lining of the digestive system. People who frequently take pain relievers are more likely to develop ulcers.
