While type 1 diabetes and gestational diabetes cannot be prevented, type 2 and prediabetes can be prevented and even reversed. With the right tools, people with type 1 and type 2 diabetes can still lead healthy lives and minimize their risk of diabetes-related complications. Everyone living with diabetes requires a personalized plan to test, monitor and control their blood glucose levels with insulin or, in the case of type 2 diabetes, oral medication. In all types, a healthy diet is an essential component of diabetes management and prevention plans.
