Ulcerative colitis is a chronic disease of the large intestine, also known as the colon, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers, that produce pus and mucous. The combination of inflammation and ulceration can cause abdominal discomfort and frequent emptying of the colon.
Ulcerative colitis is the result of an abnormal response by your body’s immune system. Normally, the cells and proteins that make up the immune system protect you from infection. In people with IBD, however, the immune system mistakes food, bacteria, and other materials in the intestine for foreign or invading substances. When this happens, the body sends white blood cells into the lining of the intestines, where they produce chronic inflammation and ulcerations.
About half of all patients with ulcerative colitis experience mild symptoms. Be sure to consult your doctor if you experience any of the following symptoms:
People suffering from ulcerative colitis often experience loss of appetite and may lose weight as a result. A feeling of low energy and fatigue is also common. Among younger children, ulcerative colitis may delay growth and development
Ulcerative colitis may affect as many as 907,000 Americans. Men and women are equally likely to be affected, and most people are diagnosed in their mid-30s. The disease can occur at any age and older men are more likely to be diagnosed than older women.
While ulcerative colitis tends to run in families, researchers have been unable to establish a clear pattern of inheritance. Studies show that up to 20 percent of people with ulcerative colitis will also have a close relative with the disease.
Your doctor will make a diagnosis based on your medical history, a physical examination, and a series of tests.
