Clinical Information
  • A chronic transmural inflammation that may involve any part of the digestive tract from mouth to anus, mostly found in the ileum, the cecum, and the colon. In crohn disease, the inflammation, extending through the intestinal wall from the mucosa to the serosa, is characteristically asymmetric and segmental. Epithelioid granulomas may be seen in some patients.
  • A condition in which the gastrointestinal tract is inflamed over a long period of time. Crohn disease usually affects the small intestine and colon. Symptoms include fever, diarrhea, stomach cramps, vomiting, and weight loss. Crohn disease increases the risk of colorectal cancer and small intestine cancer. It is a type of inflammatory bowel disease (ibd).
  • A gastrointestinal disorder characterized by chronic inflammation involving all layers of the intestinal wall, noncaseating granulomas affecting the intestinal wall and regional lymph nodes, and transmural fibrosis. Crohn disease most commonly involves the terminal ileum; the colon is the second most common site of involvement.
  • Chronic inflammation of the gastrointestinal tract, most commonly the bowel. Crohn's disease increases the risk for colon cancer.
  • Crohn's disease causes inflammation of the digestive system. It is one of a group of diseases called inflammatory bowel disease. The disease can affect any area from the mouth to the anus. It often affects the lower part of the small intestine called the ileum. Crohn's disease seems to run in some families. It can occur in people of all age groups but is most often diagnosed in young adults. Common symptoms are pain in the abdomen and diarrhea. Bleeding from the rectum, weight loss, joint pain, skin problems and fever may also occur. Children with the disease may have growth problems. Other problems can include intestinal blockage and malnutrition.treatment may include medicines, nutrition supplements, surgery or a combination of these options. Some people have long periods of remission, when they are free of symptoms.
  • Gastrointestinal disorder characterized by chronic inflammatory infiltrates, fibrosis affecting all layers of the serosa, and development of noncaseating granulomas; most common site of involvement is the terminal ileum with the colon as the second most common.
