Ulcerative colitis 


Ulcerative colitis is a form of inflammatory bowel disease (IBD) of the colon. This disease includes characteristic ulcers, or open sores. 
The main symptom of usually constant diarrhea mixed with blood, it's usually gradual onset disease. IBD is often confused with irritable bowel syndrome, a troublesome, but much less serious, condition. Ulcerative colitis has similarities to Crohn's disease, another IBD. Ulcerative colitis is an intermittent disease, with periods of symptoms, and periods that are relatively symptom-free. Although the symptoms of ulcerative colitis can sometimes diminish on their own, the disease usually requires treatment to go into remission. Ulcerative colitis occurs in 35100 people for every 100,000 in the United States.

The disease is more prevalent in northern countries of the world, as well as in northern areas of individual countries or other regions. Although ulcerative colitis has no known cause, there is a presumed genetic component. The disease may be triggered in a susceptible person by environmental factors. Although dietary modification may help in the discomfort of a person with the disease, ulcerative colitis is not thought to be caused by dietary factors. Ulcerative colitis is treated as an autoimmune disease. Treatment is with anti-inflammatory drugs, immunosuppression, and biological therapy targeting specific components of the immune response. Colectomy (partial or total removal of the large bowel through surgery) is occasionally necessary, and is considered to be a cure for the disease.
