When this happens, digestive juices-which contain hydrochloric acid and an enzyme called pepsin-can damage the intestine or stomach tissue. Treatment cures most ulcers. And symptoms usually go away quickly. Peptic ulcers that form in the stomach are called gastric ulcers. Those that form in the upper small intestine are called duodenal (say doo-uh-DEE-nul or doo-AW-duh-nul) ulcers.
