Crohn's disease is a chronic inflammatory disease of the digestive tract and it can involve any part of it - from the mouth to the anus. It typically affects the terminal ileum as well as demarcated areas of large bowel, with other areas of the bowel being relatively unaffected. It is often associated with auto-immune disorders outside the bowel, such as aphthous stomatitis and rheumatoid arthritis. Crohn's disease should not be confused with a non-progressive and non-degenerative digestive disorder called irritable bowel syndrome. IBS is not an autoimmune disease. Ulcerative colitis is a sibling autoimmune disease to Crohn's but only impacts the colon while Crohn's can impact any part of the digestive tract. Furthermore, Crohn's tends to impact multiple layers of the bowel lining which can lead to many additional and hard-to-treat complications.
Symptoms
Crohn's patients typically suffer from chronic diarrhea and disrupted digestion, making it difficult for sufferers in the acute phase of the disease to eat and/or digest food. The inflammation can be extremely painful and debilitating. Other common complications of Crohn's include fistulas of the colon, hemorrhoids, lipid absorption problems, and anemia. Bleeding is seen in 20% cases, against 98% cases in ulcerative colitis. Bruising of the shins, varying fever symptoms, indirect minor brain damage, varying levels of pain, and psychological damage is seen in many cases.
