You cannot prevent type 1 diabetes in your child. At this time, there is no known way to prevent or cure type 1 diabetes, and its exact cause remains unclear. While type 1 diabetes currently cannot be prevented, research is working to develop treatments to prevent or delay the condition. Nothing a parent or child does causes it. It is no one’s fault. Lifestyle and behavior factors, such as diet or physical activity, do not influence the risk of developing type 1 diabetes. There are also currently no proven treatment methods that can prevent progression from early stage to clinical type 1 diabetes in 100% of people. However, there are some new medications that slow down the progression of type 1 diabetes.
