With a A1c of 6.6 is great, it is below 7. As for the word Prediabetis, really means it is a warning sign that all of us have to take better care of ourselves. I went 6 years before going on any tipe of meds. With the seminars I've been to on Diabetis, the phraze of "Prediabetis" is a scarefull attack to scare everyone which is a great way for us who dont want to believe we have the "BIG D". So please take this time to really sit down and calculate what changes you have to do to take the D and put it in perspective and make the progress slow down so you dont have to go 6.6 to 7.5+ in 60 seconds.
