What is Crohn's Disease?

Answer 1

a decease affecting the gastrointestinal tract

Answer 2

Crohn’s disease is an ongoing disorder that causes inflammation of the digestive tract, also referred to as the gastrointestinal (GI) tract. Crohn’s disease can affect any area of the GI tract, from the mouth to the anus, but it most commonly affects the lower part of the small intestine, called the ileum. The swelling extends deep into the lining of the affected organ. The swelling can cause pain and can make the intestines empty frequently, resulting in diarrhea.

Crohn’s disease is an inflammatory bowel disease, the general name for diseases that cause swelling in the intestines. Because the symptoms of Crohn’s disease are similar to other intestinal disorders, such as irritable bowel syndrome and ulcerative colitis, it can be difficult to diagnose. Ulcerative colitis causes inflammation and ulcers in the top layer of the lining of the large intestine. In Crohn’s disease, all layers of the intestine may be involved, and normal healthy bowel can be found between sections of diseased bowel.

Crohn’s disease affects men and women equally and seems to run in some families. About 20 percent of people with Crohn’s disease have a blood relative with some form of inflammatory bowel disease, most often a brother or sister and sometimes a parent or child. Crohn’s disease can occur in people of all age groups, but it is more often diagnosed in people between the ages of 20 and 30. People of Jewish heritage have an increased risk of developing Crohn’s disease, and African Americans are at decreased risk for developing Crohn’s disease.

Dalziel first described Crohn’s disease in Scotland in isolated cases in 1913. However, in 1932, Crohn and colleagues named the disease Regional Ileitis. This was later changed to Regional Enteritis when, after further work, it was discovered the disease affected other areas of the gut.

It is a chronic inflammatory disease, which can affect the whole of the alimentary tract (digestive tube) from mouth to anus. The inflammation extends through all layers of the gut wall (transmural) and is characteristically patchy in distribution (skip lesions) with areas of normal tissue between.

The most commonly affected sites are the terminal ileum (the lower part of the small intestine), and the large intestine. It frequently affects the anus.

The disease has several characteristics:

1. The course of the disease is chronic with periods of remission, when patients are symptom-free, and relapses, when symptoms flare up.

2. It has a wide range of symptoms.

3. Complications outside the intestine are common.

4. There is a strong tendency for it to recur after surgery.


The symptoms of Crohn's disease vary according to its site, (i.e. small or large intestine) and severity. However, the following features occur in most cases.

1. Diarrhoea - sometimes, but not always, with blood.

2. Abdominal pain and tenderness over the intestine, often more severe in the right iliac fossa.

3. Weight loss, and in children failure to grow.

4. Fever.

5. Tiredness.

6. Sores and abscesses around the anus, which have a discharge. These may be the first signs of the disease in some patients.

7. Other symptoms not involving the intestine may occur:

I. Sore mouth due to ulcers on the tongue or inside the cheek
II. Painful, inflamed eyes (uveitis)
III. Painful, stiff or swollen joints, e.g. arthritis, ankylosing spondylitis
IV. Sore, red lumps on the skin (erythema nodosum)

Answer 5

Crohn's disease is an inflammatory bowel disease (IBD) that causes inflammation or ulceration of the digestive tract. It can affect any part of your digestive tract, but it is most common in the last part of the small intestine (ileum) and the large intestine (colon).

Crohn's disease affects the deepest layers of the lining of the digestive tract, causing deep sores called ulcers.

Crohn's disease and ulcerative colitis (which affects the colon and rectum) are the most common types of inflammatory bowel disease, with ulcerative colitis being more common.
