K26.9: Duodenal ulcer : unspecified as acute or chronic, without haemorrhage or perforation
The first part of the small intestine is also called the duodenum. This part is directly connected to the stomach and the lower part of the small intestine. The small intestine is lined with mucous membrane.
Your intestinal mucous membrane is severely damaged in one place. As a result, a deep wound has formed in your intestinal mucous membrane. There can be bleeding from the wound.
There are many reasons for a wound in the first segment of the intestines. For example, the mucous membrane may be damaged by too much gastric acid, pathogens or specific drugs.
Because of the wound, you may have pain in your stomach. It is also possible to feel nauseated and your stomach may feel unpleasantly full. You may feel exhausted. Sometimes you can also have no symptoms at all.
