Ulcerative Colitis (UC) is a bowel disorder that affects the ability of the gastrointestinal tract to function well. The main cause of ulcerative colitis is inflammation in the linings of the large intestine, rectum, and other parts of the digestive tract. Over time, this inflammation results in tiny sores called ulcers on the lining of the colon. Usually, these sores start in the rectum and spread to the other areas.

The colon makes a part of the digestive system where fluid is extracted from the undigested food, and the remaining part is preserved. But during ulcerative colitis, this inflammation may not allow the fluid to be absorbed well enough. As cells on the surface get destroyed, the sores may develop. As time passes, these ulcers may secret pus, blood, and mucus.

Ulcerative Colitis can affect people of all ages or groups though signs are more familiar between 15 and 35. Besides, it is hard to diagnose ulcerative colitis in men, more than 50.
