• A shortage of red blood cells (anemia). Some patients with Crohn's disease develop anemia because of low iron levels in the blood caused by bleeding stools or intestinal inflammation itself.

• Ulcers. Crohn's disease begins with small areas, scattered on the surface of the bowel. These areas evolves painful ulcers that penetrate deep - and sometimes Drill - bowel walls.

-Other symptoms:
Patients with severe Crohn's disease symptoms may have fever and fatigue, as well as other problems that occur outside the digestive tract, including arthritis, eye inflammation, skin diseases and liver inflammation or common bile duct channel.
-Risk Factors:

• Age. Crohn's disease can occur at any age but is more likely to do in youth. Most patients diagnosed with Crohn's disease are between 15 and 35 years;

• ethnic origin. Whites had the highest risk;

• Family history. Have a greater risk if a close relative, for example a parent, sibling or child has the disease. If a brother or sister has Crohn's disease, your risk of contracting the disease is 30 times higher than the general population;

• Where you live. If you live in an urban area or in an industrialized country, is more likely to contract Crohn's disease;

• Smoking.
-Factors that may cause exacerbation of Crohn's disease symptoms include:

• Medications

• Infections

• Hormonal changes

• Lifestyle changes, including increased stress

• Smoking.

-Diagnosis:
Crohn's disease is suspected in patients with fever, abdominal pain and uncomfortable sensations, diarrhea with or without bleeding and anal diseases.

To confirm the diagnosis, you may have to make the following analysis:

• blood analysis. The doctor might suggest blood tests to check for anemia or signs of infection.

• Colonoscopy. Direct visualization of the rectum and large intestine can be made flexible viewing tube (colonoscopy). Colonoscopy is more accurate than barium radiography in detecting small ulcers or small areas of inflammation of the colon and terminal ileum area. This is the most sensitive diagnostic test for Crohn's disease. It enables the doctor to see the entire colon using a thin tube, flexible lighting with a camera attached. During the procedure, your doctor may take a piece of tissue (biopsy) for laboratory analysis, which can help confirm the diagnosis. If there are groups of inflammatory cells called granulomas, for example, is likely to have Crohn's disease because granulomas do not occur in ulcerate colitis.



• flexible sigmoidoscopy. In this procedure, the doctor uses a thin tube, flexible lighting, to examine the sigmoid, the last half a meter of the colon. The analysis takes a few minutes. It is somewhat uncomfortable, and there is a risk colon wall penetration. May also not show and other problems that may exist above the colon or small intestine.
