K50.0: Crohn disease of small intestine

You have a disease in which the organs in the digestive tract are repeatedly becoming inflamed. In your case, the small intestine is affected.

The organs in the digestive tract include the mouth, gullet, stomach, small intestine, large intestine and anus. In your case, the organs in the digestive tract are becoming repeatedly inflamed. Various organs can be affected, and what is more, not always the same organ has to be affected. The intestines are usually affected by this disease. It is known as Crohn’s disease. The precise cause of this disorder is unknown.

The organs in the digestive tract can be inflamed to a greater or lesser degree of severity. They may be permanently inflamed or suffer bouts of inflammation. As a result, the symptoms may have a greater or lesser degree of severity. It may also be that the organs in the digestive tract have not been inflamed for a considerable time.

The disorder may cause a variety of symptoms. You may have diarrhea or abdominal pain, for example. An inflammation in the small intestine may result in you no longer being able to absorb nutrients from food so well. As a result, you may lose weight or for instance get a vitamin or iron deficiency as well. A constant inflammation may result in scars developing in the intestines. Passages between the intestines and other areas of the body may also be formed.

With the disease, other areas of the body outside of the digestive tract may also be affected. For example, the joints or skin may also become inflamed.
