Crohn's Disease

What is Crohn's disease?

Crohn's disease is an inflammatory bowel disease (IBD) that is a chronic condition that may recur at various times over a lifetime. It usually involves the small intestine, most often the lower part called the ileum. However, in some cases, both the small and large intestine are affected. Sometimes, inflammation may also affect the entire digestive tract, including the mouth, esophagus, stomach, duodenum, appendix, or anus.

Crohn's disease affects males and females equally. It appears to run in some families, with about 20 percent of people with Crohn's disease having a blood relative with some form of inflammatory bowel disease.

What are the symptoms of Crohn's disease?

The following are the most common symptoms of Crohn's disease. However, each individual may experience symptoms differently. Symptoms may include:

  • Abdominal pain, often in the lower right area
  • Diarrhea, sometimes bloody
  • Rectal bleeding
  • Weight loss
  • Fever
  • Joint pain
  • Rectal fissure
  • Rashes

With treatment and medical care, some people can have long periods of remission, sometimes for years, when they are free of symptoms. There is no way to predict when a remission may occur or when symptoms will return.

The symptoms of Crohn's disease may resemble other medical conditions or problems. Always consult your doctor for a diagnosis.

What causes Crohn's disease?

There are many theories regarding what causes Crohn's disease. One theory suggests that some agent, perhaps a virus or a bacterium, affects the body's immune system and triggers an inflammatory reaction in the intestinal wall. Although there is a lot of evidence that patients with this disease have abnormalities of the immune system, it is not known whether the immune problems are a cause or a result of the disease.
