Unfortunately, both type 1 diabetes and type 2 diabetes cannot be cured permanently. That being said, your glucose levels can potentially return to a non-diabetic range with the right care. One of the best ways to encourage better glucose levels is learning how to properly take care of your body. By eating well and exercising daily, your glucose can be lower significantly. Type 1 diabetes requires regular insulin injections, blood sugar level checks, regular physical activity, and a balanced diet. People with type 1 diabetes will need insulin treatment for the rest of their lives to prevent diabetic ketoacidosis.
