Crohn's Disease is a chronic disorder that creates inflammation in the digestive tract (also known as the GI tract). It can affect any area from the mouth to the rectum, but most commonly affects the lower part of the small intestine. The disease causes inflammation and swelling deep into the affected area, causing pain that can make the intestines empty frequently, resulting in diarrhea.
Crohn's Disease may be difficult to diagnose because the symptoms, including abdominal pain and diarrhea, are so similar to other intestinal disorders. Bleeding from the rectum, joint pain, weight loss and skin problems are other symptoms.
