Crohn's disease is an inflammatory bowel disease (IBD). It causes inflammation of the lining of your digestive tract, which can lead to abdominal pain, severe diarrhea and even malnutrition. Inflammation caused by Crohn's disease can involve different areas of the digestive tract in different people.
The inflammation caused by Crohn's disease often spreads deep into the layers of affected bowel tissue. Like ulcerative colitis, another common IBD, Crohn's disease can be both painful and debilitating, and sometimes may lead to life-threatening complications.
While there's no known cure for Crohn's disease, therapies can greatly reduce the signs and symptoms of Crohn's disease and even bring about long-term remission. With treatment, many people with Crohn's disease are able to function well.
