What are the chances of diabetes type 1 being passed down to a child?

Not big: Having type 1 dm in the family certainly increases risk for your children. Studies done years ago show that a child has a higher risk of developing diabetes if a sibling has it rather than if a parent has it. Environment and diet have a profound affect on us and are more important than genes...So take care of yourself and as a filly eat a healthful diet.

Generally speaking: If mom has type 1, the risk is about 2-4% for any children. If dad has type 1, then the risk is approximately 6-8%.
