Why is CD more common than UC in children?

Hi,

Welcome to icliniq.com.

I have read very carefully about your queries.

1. Why Crohn's disease is more common than ulcerative colitis in children?

In the preschool group, ulcerative colitis is more common than Crohn's disease, but in older children, Crohn's disease is more common than ulcerative colitis. In the last few years, the incidence of Crohn's disease is increasing, but the incidence of ulcerative colitis remains unchanged. The exact cause of this difference is still unknown. There are some hypotheses, such as dietary modification, urbanization but nothing is established.

2. Why Crohn's disease occurs in children?

The reason is both genetic and environmental. When genetically susceptible people are exposed to environmental factors, they develop Crohn's disease. But you asked why early in children if they have no family or genetic connection? As mentioned, it needs both components for development. There is some research on the early development of Crohn's disease. Children (genetically susceptible) who are less breastfed, taking more antibiotics, more fatty food, and less fibrous food are more likely to develop early. Besides this, if an affected family member is present, development increases in the early period.

I hope this helps you. If you want to know more, feel free to contact me. Thanks.
