Ulcerative colitis is a type of inflammatory bowel disease (IBD) that affects the lining of the large intestine (colon) and rectum. Crohn's disease is a related condition.
Inflammatory bowel disease - ulcerative colitis; IBD - ulcerative colitis
Causes, incidence, and risk factors
The cause of ulcerative colitis is unknown. People with this condition have problems with the immune system, but it is not clear whether immune problems cause this illness. Although stress and certain foods can trigger symptoms, they do not cause ulcerative colitis.
Ulcerative colitis may affect any age group, although there are peaks at ages 15 - 30 and then again at ages 50 - 70.
The disease can begin the rectal area, and may involve the entire large intestine over time. It may also start in the rectum and other parts of the large intestine at the same time.
Risk factors include a family history of ulcerative colitis, or Jewish ancestry.
The symptoms vary in severity and may start slowly or suddenly. About half of people only have mild symptoms. Others have more severe attacks that occur more often. Many factors can lead to attacks, including respiratory infections or physical stress.

Other symptoms that may occur with ulcerative colitis include the following:
Signs and tests
Colonoscopy is also used to screen people with ulcerative colitis for colon cancer. Ulcerative colitis increases the risk of colon cancer. If you have this condition, you should be screened with colonoscopy about 8 - 12 years after being diagnosed. You should have a follow-up colonoscopy every 1 - 2 years.
Other tests that may be done to help diagnose this condition include:
The goals of treatment are to:
Hospitalization is often needed for severe attacks. Your doctor may prescribe corticosteroids to reduce inflammation. You may be given nutrients through a vein (intravenous line).
DIET AND NUTRITION
Certain types of foods may worsen diarrhea and gas symptoms, especially during times of active disease. Diet suggestions include:
You may feel worried, embarrassed, or even sad or depressed about having a bowel accident. Other stressful events in your life, such as moving, or losing a job or a loved one can cause digestive problems.
Ask your doctor or nurse for tips on your to manage your stress.
Medicines that may be used to decrease the number of attacks include:
Surgery to remove the colon will cure ulcerative colitis and removes the threat of colon cancer. Surgery is usually recommended if you have:
Most of the time, the entire colon, including the rectum, is removed (total proctocolectomy with ileostomy). Afterwards, you may need a surgical opening in the abdominal wall (ileostomy), or a procedure that connects the small intestine to the anus to gain more normal bowel function.
Social support can often help with the stress of dealing with illness, and support group members may also have useful tips for finding the best treatment and coping with the condition.

Symptoms are mild in about half of people with ulcerative colitis. You are less likely to respond well to medicines if your disease is more severe.
Permanent and complete control of symptoms with medications is unusual. Cure is only possible through complete removal of the large intestine.
The risk of colon cancer increases in each decade after ulcerative colitis is diagnosed.
Repeated swelling (inflammation) leads to thickening of the intestinal wall and rectum with scar tissue. Death of colon tissue or severe infection (sepsis) may occur with severe disease.
Calling your health care provider
Call your health care provider if:
Because the cause is unknown, prevention is also unknown.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may make symptoms worse.
Due to the risk of colon cancer associated with ulcerative colitis, screening with colonoscopy is recommended.
The American Cancer Society recommends having your first screening:
Have follow-up examinations every 1 - 2 years.
