Top 10 Causes of Colitis

Colitis occurs when your colon and large intestine get swollen or inflamed. It is usually the result of some underlying issues such as autoimmune disease or infection. If left untreated properly, this can be a very serious disease that would trigger many complications. Since the treatments of colitis depend on the cause, it is important to have an exact diagnosis. With that in mind, here are 10 common triggers of colitis.


One of the most common causes of colitis in most people is an infectious disease. Indeed, infectious colitis would result from any form of infection, including parasites, viruses, and bacteria. Children are often at a higher risk of developing due to a weaker immune system. Some common infectious conditions that would trigger colitis include Entamoeba histolytica, cytomegalovirus, and salmonella, shigella, or Escherichia coli. To minimize the risk, it is important to keep your living space always clean and hygienic. Also, make sure to stay away from people with these conditions to prevent the virus or bacteria from spreading and causing disease. [1]
