Hello I found this information on the national association for crohns and colitis uk I find they have a lot of useful information sheets.
What are the chances of my child having IBD?
Parents with IBD are slightly more likely to have a child who develops IBD. If one parent has IBD, the risk of a child developing IBD is about 2% for Ulcerative Colitis and 5% for Crohn’s Disease, although it may be higher in some population groups. That is, for every 100 people with UC, about 2 of their children might be expected to develop IBD at some time in their lives. For every 100 people with Crohn’s, about 5 of their children might be expected to develop IBD. If both parents have IBD, the risk can rise to 35%. However, we still cannot predict exactly how IBD is passed on. Even with genetic predisposition, other additional factors are needed to trigger IBD.
So from this it seems the statistics are very low but I would like to add neither of my parents and no one in my family have crohns disease but I still have it. I must just have the right combination of genes for me to get the disease so it can happen to anyone.
Wishing you all the best x
