Ulcerative colitis causes inflammation of the large intestine. The inflammation caused by ulcerative colitis is located in one continuous portion of the intestine. The cause of ulcerative colitis is unknown though it can be hereditary. Ulcerative colitis also is thought to be the result of the intestine’s immune system malfunctioning, which causes chronic inflammation.
Ulcerative colitis can affect both men and women and can occur at any age; however, ulcerative colitis most likely occurs between the ages of 15 to 30 or 50 to 70. People of Ashkenazi Jewish descent have a high risk of developing ulcerative colitis.
