What Are the Causes of Colitis?

Colitis is a condition that affects millions of Americans. The term colitis is used to describe any inflammation of the colon and results in abdominal pain, blood in the stool and chronic diarrhea.

Infectious Colitis

Infectious colitis is caused by a virus or bacteria such as Shigella, E Coli or Salmonella. Often this form of colitis can be treated with antibiotics.

Ischemic Colitis

Ischemic colitis occurs when the arteries that provide blood to the colon constrict, causing the colon to become inflamed.

Ulcerative Colitis

Ulcerative colitis is an autoimmune illness that causes the body's immune system to attack the colon, causing it to become inflamed.

Microscopic Colitis

Microscopic colitis is comprised of two different forms of colitis, collagenous and lymphocytic. The layers of the colon wall can trap collagen or lymphocytes, causing it to become inflamed.

Chemical Colitis

Chemical colitis is caused when a chemical is inserted into the colon, which causes the colon to become inflamed. Enemas can sometimes lead to this type of colitis, when harsh chemicals are used.
