Crohn's disease is a nonspecific inflammatory disease that affects the small intestine, large intestine, and can even affect any part of the digestive tract from the mouth to the colon and the anus. The disease is familial, usually in children.

Crohn's disease is an inflammatory bowel disease with symptoms of abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition. The inflammation caused by Crohn's disease often spreads deep into the layers of intestinal tissue, which is both painful and debilitating, and can sometimes lead to life-threatening complications.
