Peptic ulcer disease is a condition characterized by defects in the mucous membrane of the gastrointestinal organs, ranging in size from 0.5 cm to 3 cm or more. The most common forms include stomach ulcers or duodenal ulcers, as well as peptic and gastroduodenal ulcers.
Stomach ulcers are more common than duodenal ulcers, though defects may sometimes be found in both organs simultaneously. The disease may be classified as newly diagnosed or recurrent (chronic). Chronic stomach ulcers can lead to complications such as bleeding, perforation of the stomach or intestinal wall, and stenosis. Therefore, it is important to seek medical attention at the first signs of the disease.
