What Is It?
Colitis can be defined as the swelling of the inner lining of the colon. There are various sources of this swelling such as infection, inflammatory bowel disease, ischemic colitis, allergic reactions, and microscopic colitis. Also, the disease can be originated from several factors such as heredity, and stress.
Causes of Colitis
1. Heredity: If one has a parent, or sibling with the disease, it’s very likely to develop ulcerative colitis. Scientists suspect that genetic makeup may play a contributing role.
2. Environment: Infection from environment are suspected of triggering the disease in people who have a genetic susceptibility. However, the main trigger has not been reliably proven. The bacteria that usually exist in the colon also have an important role in the development of the disease.
3. Infectious agents or environmental toxins: No particular agent has been associated reliably with either form of inflammatory bowel disease. Viruses have been described in tissue from people with swelling bowel disease, but there is no compelling evidence. Colitis can be severe like E. coli infection or chronic such as ulcerative colitis. Infections, ischemia (poor blood flow), allergy to food, intolerances to food proteins, lack of normal bacterial flora or stool, injury due to radiation, idiopathic are causes of the said disease.
