My A1C is 6.6 and my glucose is 139 fasting. I have an appointment with the doctor in two weeks. Will I need medication to lower my `A1C level and glucose, or can I do it with diet and exercise? I know that diabetes 2 is a potentially serious disease, but at this point, am I in the mild range or severe range? Will I ever be able to eat ice cream, cake, cookies on occasion?
