K63.3: Ulcer of intestine
You have an open sore in the mucous membrane of your small intestine.
The small intestine is the longest section of the digestive tract. It consists of 3 sections. The 1st section begins immediately after the stomach and is called the duodenum. The gallbladder and the pancreas secrete the digestive juices in this section. The jejunum and ileum sections come next. The nutrients are absorbed into the blood from the food in the small intestine. The small intestine is followed by the large intestine.
The intestines are lined with mucous membrane. The mucous membrane can become inflamed and thus damaged. If the mucous membrane is severely damaged, an open sore can then be formed.
If the mucous membrane in the small intestine is damaged, this may for instance cause bleeding in the intestines. You may then see blood in your feces, or the feces will have a black appearance. You may also have pain in your abdomen. It is also possible that you will feel nauseated.
