What is a stomach ulcer?

A stomach ulcer, also called a gastric ulcer, is an open sore that develops in your stomach lining. You can also get one in your duodenum, the first part of the small intestine that your stomach feeds into. Duodenal ulcers and stomach ulcers are both types of peptic ulcers. They’re named for pepsin, one of the digestive juices that are found in the stomach and that sometimes leak into the duodenum. These juices are a contributing factor in peptic ulcer disease.

Peptic ulcers occur when the protective mucous lining in your stomach and duodenum has been eroded, allowing gastric acids and digestive enzymes to eat away at your stomach and duodenal walls. This eventually results in open sores that are continually irritated by the acid. If left untreated, they can begin to cause serious complications, such as internal bleeding. Over time, they can even wear a hole all the way through. This is a medical emergency.
