Crohn's disease is an
inflammatory bowel disease characterized by severe, chronic inflammation of the intestinal wall or any portion of the gastrointestinal
tract. The lower portion of the small intestine (ileum) and the rectum are most commonly affected by this disorder. Symptoms
may include watery diarrhea, abdominal pain, fever, and weight loss. The symptoms of Crohn's disease can be difficult to manage
and proper diagnosis is often delayed. The exact cause of Crohn's disease is unknown.
