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.

People with psoriasis are 2.5 times more likely to have Crohn's disease and 1.6 times more likely to have ulcerative colitis. Psoriasis is associated with a number of digestive disorders.

Crohn's disease is a regional inflammatory bowel disease that can occur in all subjects regardless of gender or age, including children, but most patients with Crohn's disease are between 16-30 and 60-80 years old. The cause of the disease is still not determined with certainty, if not detected early and treated, it can cause many dangerous complications.

Crohn's disease, also known as regional enteritis, is often more difficult to diagnose than other inflammatory bowel diseases. This is because Crohn's is not limited to any one area of the gastrointestinal (GI) tract, appearing anywhere from the mouth to the anus, and has a wider range of symptoms.
