Risk of having another child with diabetes type 1

Hello everyone; my son is having DM from the age of 6 and he is the only child, we (me and his mother) are non diabetics. I want to ask what is the percentage or incidence of having another child with diabetes?

The American Diabetes Association and Joslin Diabetes Center have some statistics on this issue. According to Joslin:

If an immediate relative (parent, brother, sister, son or daughter) has type 1 diabetes, one’s risk of developing type 1 diabetes is 10 to 20 times the risk of the general population; your risk can go from 1 in 100 to roughly 1 in 10 or possibly higher, depending on which family member has the diabetes and when they developed it.

If one child in a family has type 1 diabetes, their siblings have about a 1 in 10 risk of developing it by age 50.

As @Boerenkool shows, there’s nothing like having some actual data to work with. OTOH, if you want anecdotal reassurance, you can have a look at this very long-running thread from the old TUD site.

I’m certainly on that list. Out of my very large extended family, including 5 siblings and dozens of aunts and uncles and their offspring, the only other T1 is the daughter of one of my many first cousins.

Thanks For the information.

Thank you, it’s a high percentage 1 in 10 ! We have to think twice before planning for another child. But is there any way to predict it before labour? I think it’s impossible to know that during pregnancy.

Thanks alot .

That’s right and there is no way to predict it after pregnancy either.
