Which demographic is most likely to be affected by Ulcerative Colitis?

Ulcerative Colitis is a type of inflammatory bowel disease that primarily affects the lining of the large intestine and rectum. The demographic most commonly affected is young adults, particularly those between the ages of 15 and 30. This age group experiences the onset of symptoms more frequently, making them more susceptible to this condition.

The reason for this prevalence in young adults is not entirely understood, but it's believed that genetic, environmental, and immune system factors play a significant role. As the disease primarily manifests during young adulthood, it can significantly impact the quality of life due to its chronic nature and the symptoms experienced, such as abdominal pain and frequent diarrhea.

In contrast, while Ulcerative Colitis can occur in children and older adults, the incidence rates are considerably lower in these groups. Infants are also not typically affected by this condition, as it primarily arises in older children and young adults. Therefore, young adults represent the demographic that is most affected by Ulcerative Colitis.
