Crohn's disease and ulcerative colitis are the illnesses called inflammatory bowel disease / IBD. These two diseases are very much alike.
In Crohn's disease, inflammation can be found in the lining of the intestine. It can also involve the whole thickness of the bowel wall. Crohn's disease is usually in the lower part of the small intestine, called the ileum. However, it can affect any part of the digestive tract, from where food is taken in (the mouth) to where food comes out (the anus).
Ulcerative colitis only affects the colon. The inflammation can cause pain. It can also make the colon empty often, which causes diarrhea.
Some patients with Crohn's disease have long periods of remission (when symptoms disappear). This may last months or years. However, there is no way to tell when a remission will happen or when disease symptoms will return. There is no cure for Crohn's disease.
About one million Americans have inflammatory bowel disease. People of all age groups can have Crohn's disease, but it usually begins in the late teens and early adulthood. Twenty percent of all Crohn's cases affect children.
The disease affects males and females equally, but Crohn's disease tends to run in families and certain ethnic groups. About 20% of people with Crohn's disease have a blood relative with some type of IBD. For those patients with a family history, it is very likely that Crohn's disease will begin in the teens and twenties.
In a film created by Jesse Dylan, care providers participating in ImproveCareNow discuss how the program's collaborative approach is improving the health of children with Crohn’s disease and ulcerative colitis.
