As with most things, if you are told you are 'Pre Diabetic' that should be a wake up call to change your lifestyle to make sure that you don't develop into full Diabetes.
It's a pity as others have mentioned many don't get told anything other than 'avoid sugars'........if only it was that simple ! As many of us know it is a complicated balancing act to avoid weight gain, Bg levels rising way too high after meals etc.......with the proper advice all of that can be controlled and progression towards Diabetes avoided or delayed for many years.
As for Diabetes being progressive.........no it isn't. You need to have tight control of all areas otherwise it can be. Assuming that it is and will be progressive is a negative thought and should be avoided at all costs. Using tight Bg control can not only improve things but in many cases actually reverse the symptoms, reduce any medications. It is hard work but not impossible.
I myself was on a 'shed load' of medications, then moved onto Byetta.........since then, Meds reduced to just 2 Metformin daily, Byetta reduced to 5ug dose twice daily, eyesight improved to my pre-Diabetic levels so no longer need glasses to drive. Weight lost 5 1/2 stone. Energy and fitness levels vastly improved. Nothing progressive there !!
So, forget all the 'doom and gloom' about it
will get worse........it doesn't have to. It's what YOU make it. Me, I am making it take a back seat, it's always there........but I'm the Driver.
