Ulcerative colitis causes inflammation in the digestive tract and forms tiny open spores or ulcers in the digestive tract. It happens due to the overresponsive behaviour of the immune system. The immune system fights bacteria and viruses that can damage the body through inflammation. It disappears as the viruses get destroyed. But in Ulcerative colitis, the inflammation does not go away and continues damaging walls of the digestive tract.
Endoscopic procedures accompanied with biopsy are the best diagnostic measures for UC. Stool tests and blood tests help in studying conditions like anaemia or the presence of white blood cells or proteins in stool that indicate ulcerative colitis.
Treatment involves drug therapy or surgery. Medications work on the principle that UC has a period of relapse and remission. Relapse is when bowel flares up, and remission is when the inflammation calms down. Treatment aims to treat relapse, maintain the condition and help the healing of the bowel.
The exact cause of Ulcerative colitis is still under research. However, some theories agree that it results from malfunctioning the immune system. Studies have shown that Ulcerative colitis tends to pass in genes and increase the chances of a person becoming more prone to the disease if he has close relative suffering from the same.
