Crohn's disease (also known as regional enteritis) is a chronic, episodic, inflammatory condition of the gastrointestinal tract characterized by transmural inflammation (affecting the entire wall of the involved bowel) and skip lesions (areas of inflammation with areas of normal lining between). Crohn's disease is a type of inflammatory bowel disease (IBD) and can affect any part of the gastrointestinal tract from mouth to anus; as a result, the symptoms of Crohn's disease vary among afflicted individuals. The main gastrointestinal symptoms are abdominal pain, diarrhea (which may be bloody) or constipation, vomiting and weight loss. Crohn's disease can also cause complications outside of the gastrointestinal tract such as skin rashes, arthritis, and inflammation of the eye. ...

Although the cause of Crohn's disease is not known, it is believed to be an autoimmune disease that is genetically linked. The condition occurs when the immune system contributes to damage of the gastrointestinal tract by causing inflammation.

Unlike the other major type of IBD, ulcerative colitis, there is no known medical or surgical cure for Crohn's disease. Instead, a number of medical treatments are utilized with the goal of putting and keeping the disease in remission.
