Ileitis is inflammation in the ileum, which is part of the small intestine. It is most commonly caused by Crohn’s disease, but sometimes, other conditions, like infections or ischemia can cause it. Overuse of over-the-counter pain medications may also cause ileitis in some people.

It is possible to recover from an acute episode of ileitis, but if this condition occurs with Crohn’s disease, it is likely to be chronic. Crohn’s is an inflammatory bowel disease that typically involves periods of remission and relapse. Treatment can make symptoms of Crohn’s disease manageable, but it is possible to experience serious complications with this condition. 

While Crohn’s disease is the most common cause of ileitis, it is possible to experience ileitis without having Crohn’s disease. For example, an intestinal infection or irritation may cause a temporary bout of ileitis.

Treatment for ileitis depends upon the cause. A doctor may perform an X-ray to examine the small intestine and determine the cause of ileitis and the best course of treatment. If ileitis occurs through the course of Crohn’s disease, you will likely require medications to treat it. Many people with Crohn’s disease also require surgery at some point.
