Crohns disease is a chronic, inflammatory disease of the gastrointestinal tract most often in the ileum and large intestine. Inflammation can lead to abscesses and ulcers, and chronic symptoms may result in fibrosis, stenosis and bowel obstruction.
In Our Own Words
Crohns disease is an inflammatory gastrointestinal disease of unknown cause that affects the bowels. Most commonly, people with Crohns disease are affected with diarrhea, abdominal pain, weight loss and fever. Inflammation and ulcers are most common at the end of the small intestine (ileum) and in the large intestine, but can occur in other areas.
Crohns disease has similarities to ulcerative colitis, and both diseases are considered inflammatory bowel diseases, but the two entities are distinct with different patterns of involvement. Genetics and the environment have been linked to this condition. In addition to affecting the gastrointestinal (GI) tract, Crohns also causes joint pain and fatigue. Patients may experience periodic remissions.
