Causes of ulcerative colitis:
The cause of ulcerative colitis is unknown. It may affect any age group, although there are peaks at ages 15 - 30 and then again at ages 50 - 70.
The disease usually begins in the rectal area and may eventually extend through the entire large intestine. Repeated swelling (inflammation) leads to thickening of the wall of the intestine and rectum with scar tissue. Death of colon tissue or sepsis may occur with severe disease.
The symptoms vary in severity and may start slowly or suddenly. Many factors can lead to attacks, including respiratory infections or physical stress.
Causes of Crohn's disease: While the exact cause of Crohn's disease is unknown, the condition is linked to a problem with the body's immune system response.
Normally, the immune system helps protect the body, but with Crohn's disease the immune system can't tell the difference between good substances and foreign invaders. The result is an overactive immune response that leads to chronic inflammation. This is called an autoimmune disorder.
There are five different types of Crohn's disease:
Ileocolitis is the most common form. It affects the lowest part of the small intestine (ileum) and the large intestine (colon). Ileitis affects the ileum. Gastroduodenal Crohn's disease causes inflammation in the stomach and first part of the small intestine, called the duodenum. Jejunoileitis causes spotty patches of inflammation in the top half of the small intestine (jejunum). Crohn's (granulomatous) colitis only affects the large intestine.
A person's genes and environmental factors seem to play a role in the development of Crohn's disease. The body may be overreacting to normal bacteria in the intestines.
The inflammation related to Crohn's disease frequently occurs at the end of the small intestine that joins the large intestine, but it may occur in any area of the digestive tract. There can be healthy patches of tissue between diseased areas. The ongoing inflammation causes the intestinal wall to become thick.
