What are the complications of Crohn's Disease ?
Complications of Crohn's disease can include
                
- bowel obstruction. Crohn's disease can thicken the wall of the intestine. Over time, the thickened areas of the intestine can narrow, which can block the intestine. A partial or complete obstruction, also called a bowel blockage, can block the movement of food or stool through the intestines. A complete bowel obstruction is life threatening and requires immediate medical attention and often surgery.  - fistulasabnormal passages, or tunnels, between two organs, or between an organ and the outside of the body. How a health care provider treats fistulas depends on their type and severity. For some people, fistulas heal with medication and diet changes, while other people will need to have surgery.  - anal fissuressmall tears in the anus that may cause itching, pain, or bleeding. Most anal fissures heal with medical treatment, including ointments, warm baths, and dietary changes.  - ulcers. Inflammation anywhere along the GI tract can lead to ulcers or open sores in a person's mouth, intestines, anus, and perineumthe area between the anus and the sex organs. In most cases, the treatment a health care provider prescribes for Crohn's disease will also treat the ulcers.  - malnutritiona condition that develops when the body does not get the right amount of vitamins, minerals, and nutrients it needs to maintain healthy tissues and organ function. Some people may need IV fluids or feeding tubes to replace lost nutrients and fluids.  - inflammation in other areas of the body. The immune system can trigger inflammation in the      - joints    - eyes    - skin
                
Health care providers can treat inflammation by adjusting medications or prescribing new medications.
                

                
Crohn's Disease and Colon Cancer   People with Crohn's disease in the large intestine may be more likely to develop colon cancer. People who receive ongoing treatment and remain in remission may reduce their chances of developing colon cancer.   People with Crohn's disease should talk with their health care provider about how often they should get screened for colon cancer. Screening can include colonoscopy with biopsies. Such screening does not reduce a person's chances of developing colon cancer. Instead, screening can help diagnose cancer early and improve chances for recovery.
