Living With Crohn's Disease?
What is Crohn's disease?
Crohn's disease is a chronic (long-term) condition that causes inflammation of the digestive, or gastrointestinal (GI), tract. It is one of the two main types of inflammatory bowel disease (IBD); the other is ulcerative colitis.
Crohn's can affect any part of the GI tract from the mouth to the anus, but it most often involves the end of the small intestine (the ileum) and the beginning of the large intestine (the colon). The inflammation can extend deep into the layers of the bowel wall, and it often appears in patches, with healthy areas in between inflamed sections.
The exact cause is not fully understood. Crohn's is believed to result from a combination of an overactive immune response, genetics (it can run in families), and environmental factors. It is not caused by anything a person did, and it is not contagious. Diet and stress may worsen symptoms but do not cause the disease.
