Translations:Ulkus/2/en

Gastric or duodenal ulcers are circumscribed mucous membrane defects that reach the deeper layers of the stomach and intestinal wall and whose diameter can range from a few millimetres to more than three centimetres. They usually result from an inflammation of the gastric mucosa, the so-called chronic gastritis, which lasts for weeks, months or even years and is always accompanied by a loss of tissue substance.
