What is peptic ulcer?

A peptic ulcer is erosion in the lining of the stomach or duodenum (the first part of the small intestine). The word “peptic” refers to pepsin, a stomach enzyme that breaks down proteins. If a peptic ulcer is located in the stomach it is called a gastric ulcer.

Small ulcers may not cause any symptoms. Large ulcers can cause serious bleeding. Most ulcers occur in the first layer of the inner lining. A hole that goes all the way through is called a perforation of the intestinal lining. A perforation is a medical emergency.

Alternative Names:

Ulcer - peptic; Ulcer - duodenal or gastric; Duodenal ulcer
