Ulcerative colitis is a severe inflammatory disease that results in the formation of ulcers within the inner lining of vital organs of the digestive system- the large intestine, colon, and rectum. People suffering from this condition have symptoms on and off, which vary among individuals. Although it remains a medical mystery, researchers have made great strides toward uncovering the potential causes of ulcerative colitis. While more research is warranted to explain better what triggers this chronic intestinal disorder, there are some known risk factors that may contribute to its development or progression. In this article, we will explore the possible underlying causes of ulcerative colitis.


How is Ulcerative Colitis Caused?

Listed below are the major risk factors of ulcerative colitis:

  • Autoimmune reactions: When the immune system tries to fight off a viral or bacterial infection, sometimes the immune response becomes irregular and aggravated, attacking its own cells in the digestive tract. White blood cells, which play a role in protection, start attacking gut cells, the normal microflora of the gut, and food, resulting in inflammation and the formation of ulcers.
  • Hereditary genes may also be responsible for the development of the disease.
  • Diet and stress: Previously, diet and stress were considered two factors that led to the development of ulcerative colitis. But now, with research, it has been found that diet and stress aggravate the symptoms of the disease and are not direct causes of ulcerative colitis.


Some other risk factors that can contribute to ulcerative colitis development are:

  • Age: Ulcerative colitis mostly develops either before 30 years or after 60 years of age. However, ulcerative colitis can manifest at any age.
  • Race and ethnicity: people of Ashkenazi Jewish descent are more likely to develop the disease.
  • Family history: People with a family history of this condition are more prone to develop the disease.
