What percentage of people pass down Crohns disease to their children?

The risk of a person developing Crohn's disease if a parent has the condition varies and depends on several factors. If one parent has Crohn's disease, the risk of their child developing it is roughly around 5-10%. This means that the majority of children (90-95%) of a parent with Crohn's disease will not inherit the condition.

However, it's essential to consider that genetics is not the only factor that determines if someone develops Crohn's disease. Environmental and lifestyle factors, such as smoking, stress, and diet, can also play a crucial role.

If you have Crohn's disease and are considering having children, it's advisable to consult with a genetic counselor or healthcare professional to assess your specific risk and discuss any concerns you may have.
