Peptic Ulcer
Alternate Names : Duodenal Ulcer, Ulcer - Duodenal or Gastric, Ulcer - Peptic
Definition
Ulcers are erosions (wearing away or corrosion) in the lining of the stomach or duodenum. (The duodenum is the first part of the small intestines, which connects to the stomach.) An ulcer in the stomach is called a gastric ulcer. An ulcer in the duodenum is called a duodenal ulcer. Together, ulcers of the stomach and duodenum are referred to as peptic ulcers.
Most ulcers are erosions of the first layer of the inner lining. If the hole goes all the way through, this is called a perforation of the intestinal lining. This can cause shock and is a medical emergency.
